Our government spends substantial amount of resources in educating our children. Additionally several welfare schemes are introduced aimed especially at underprivileged children to ensure that all of them complete a basic level of education. In spite of these measures many students do not complete their basic education.
The aim of this project is to formulate a Supervised Learning Algorithm that will aid in identifying such students who have a higher likelihood of not completing their education.
To perform this task the algorithm will perform Logistic Regression Analysis on historical data of students from a given school. The historical data includes basic background information (features) such as gender, community, number of siblings etc. It must be noted that the historical data also contains information on whether the student completed his/her education, which is the outcome we are interested in. Typically a student finishing education will be denoted using a value of 1 and a student not finishing will be denoted with a value of 0.
Based on the training (historical) data a logistic classifier can be built. Such a classifier after learning from the training set will develop specific weightages for each of the features. These weightages can then be extrapolated into an equation that can be used for prediction.
That is we can apply the equation on a current student (whose background we already know) to calculate the probability that he/she will complete his/her education.
Such an algorithm will be beneficial to government agencies since it can serve as an early warning system using which they can take more proactive action to prevent a student from dropping out. Policy makers can also use it as a tool to identify schools that are more vulnerable and direct their resources and energies to help them.

Discovering Student Dropout Prediction through Deep Learningijtsrd
There have been increased incidences of dropout that have been noticed in the universities in the recent years. These increased reports have been instrumental in introducing the graduation rate of the course completion rate for majority of universities all over the globe. Dropouts are highly undesirable and are an indication of some underlying inconsistencies that have been plaguing the course since a long time. Therefore, an effective system for the purpose of prediction of the dropout rate is the need of the hour. To reach these goals this research article has utilized machine learning approaches. The proposed methodology utilizes the K Nearest Neighbor, Fuzzy Artificial Neural Network and Decision Tree. This approach has been illustrated in utmost detail in this research article, highlighting the execution of the various important modules of the methodology. The experimentation has been performed to achieve the performance of the approach which has yielded highly accurate results.

Unique to ORION, students BEGIN by taking a quick diagnostic
for any chapter. This will determine each student’s baseline
proficiency on each topic in the chapter. Students see their
individual diagnostic report to help them decide what to do next
with the help of ORION’s recommendations.
Students can easily access ORION from multiple places within WileyPLUS. It does not require any additional
registration, and there will not be any additional charge for students using this adaptive learning system.
ABOUT THE ADAPTIVE ENGINE
ORION includes a powerful algorithm that feeds questions to students based on their responses to the
diagnostic and to the practice questions. Students who answer questions correctly at one difficulty level
will soon be given questions at the next difficulty level. If students start to answer some of those questions
incorrectly, the system will present questions of lower difficulty. The adaptive engine also takes into account
other factors, such as reported confidence levels, time spent on each question, and changes in response
options before submitting answers.
The questions used for the adaptive practice are numerous and are not found in the WileyPLUS assignment
area. This ensures that students will not be encountering questions in ORION that they may also encounter
in their WileyPLUS assessments.
ORION also offers a number of reporting options available for instructors, so that instructors can easily monitor
student usage and performance.
For each topic, students can either STUDY, or PRACTICE. Study directs students to the
specific topic they choose in WileyPLUS, where they can read from the e-textbook or
use the variety of relevant resources available there. Students can also practice, using
questions and feedback powered by ORION’s adaptive learning engine. Based on
the results of their diagnostic and ongoing practice, ORION will present students with
questions appropriate for their current level of understanding, and will continuously adapt
to each student to help build proficiency.
ORION includes a number of reports and ongoing recommendations for students to help
them MAINTAIN their proficiency over time for each topic.

A survey was also administered to understand pain points.
A Public Cloud Based SOA Workflow for Machine Learning Based Recommendation A...Ram G Athreya
Over the past decade the field of Cloud Computing has been the focus of intensive research. In this paper we propose a framework that will simulate the architectural setup of a cloud environment and examine how it can leverage Apriori and Sequential Pattern based recommendation algorithms through R. Furthermore, we present a multi layered application encompassing its backend architecture, user interface built using the responsive web design technique and its development workflow. The proposed system was also exhaustively load tested using Apache JMeter to ensure its reliability at scale and the experimental results are presented.
Semi-Automated Security Testing of Web applicationsRam G Athreya
Market research survey on Internet attacks reports that more than 70% of the attacks are on the application layer. This is because 1. More valuable information (electronic money details) is at the application level and 2. Relatively there are more unaddressed vulnerabilities. Considering the fact that there are still inadequate adoption of security development practices across the numerous application development communities, the security testing of the web applications becomes highly critical and rigorous.
In our project we have created a penetration testing tool (Black Box Testing Tool) that will check for vulnerabilities in a semi – automated fashion on a target web application. We have tested and demonstrated the functionality and effectiveness of our tool by running this tool on 1. On a target vulnerable web application created by us and 2. On live web sites of a customer organization. The results have been revealing and have been documented appropriately in the following report. We have also provided recommendations as part of corrective action against the discovered vulnerabilities and statements of best practices based on ISO27002 and such other organizations as a preventive action in order to avoid recurrence of such vulnerabilities.

End-to-end pipeline agility - Berlin Buzzwords 2024Lars Albertsson
We describe how we achieve high change agility in data engineering by eliminating the fear of breaking downstream data pipelines through end-to-end pipeline testing, and by using schema metaprogramming to safely eliminate boilerplate involved in changes that affect whole pipelines.
A quick poll on agility in changing pipelines from end to end indicated a huge span in capabilities. For the question "How long time does it take for all downstream pipelines to be adapted to an upstream change," the median response was 6 months, but some respondents could do it in less than a day. When quantitative data engineering differences between the best and worst are measured, the span is often 100x-1000x, sometimes even more.
A long time ago, we suffered at Spotify from fear of changing pipelines due to not knowing what the impact might be downstream. We made plans for a technical solution to test pipelines end-to-end to mitigate that fear, but the effort failed for cultural reasons. We eventually solved this challenge, but in a different context. In this presentation we will describe how we test full pipelines effectively by manipulating workflow orchestration, which enables us to make changes in pipelines without fear of breaking downstream.
Making schema changes that affect many jobs also involves a lot of toil and boilerplate. Using schema-on-read mitigates some of it, but has drawbacks since it makes it more difficult to detect errors early. We will describe how we have rejected this tradeoff by applying schema metaprogramming, eliminating boilerplate but keeping the protection of static typing, thereby further improving agility to quickly modify data pipelines without fear.
Enhanced Enterprise Intelligence with your personal AI Data Copilot.pdfGetInData
Recently we have observed the rise of open-source Large Language Models (LLMs) that are community-driven or developed by the AI market leaders, such as Meta (Llama3), Databricks (DBRX) and Snowflake (Arctic). On the other hand, there is a growth in interest in specialized, carefully fine-tuned yet relatively small models that can efficiently assist programmers in day-to-day tasks. Finally, Retrieval-Augmented Generation (RAG) architectures have gained a lot of traction as the preferred approach for LLMs context and prompt augmentation for building conversational SQL data copilots, code copilots and chatbots.
In this presentation, we will show how we built upon these three concepts a robust Data Copilot that can help to democratize access to company data assets and boost performance of everyone working with data platforms.
Why do we need yet another (open-source ) Copilot?
How can we build one?

Global Situational Awareness of A.I. and where its headedvikram sood
You can see the future first in San Francisco.
Over the past year, the talk of the town has shifted from $10 billion compute clusters to $100 billion clusters to trillion-dollar clusters. Every six months another zero is added to the boardroom plans. Behind the scenes, there’s a fierce scramble to secure every power contract still available for the rest of the decade, every voltage transformer that can possibly be procured. American big business is gearing up to pour trillions of dollars into a long-unseen mobilization of American industrial might. By the end of the decade, American electricity production will have grown tens of percent; from the shale fields of Pennsylvania to the solar farms of Nevada, hundreds of millions of GPUs will hum.
The AGI race has begun. We are building machines that can think and reason. By 2025/26, these machines will outpace college graduates. By the end of the decade, they will be smarter than you or I; we will have superintelligence, in the true sense of the word. Along the way, national security forces not seen in half a century will be un-leashed, and before long, The Project will be on. If we’re lucky, we’ll be in an all-out race with the CCP; if we’re unlucky, an all-out war.
Everyone is now talking about AI, but few have the faintest glimmer of what is about to hit them. Nvidia analysts still think 2024 might be close to the peak. Mainstream pundits are stuck on the wilful blindness of “it’s just predicting the next word”. They see only hype and business-as-usual; at most they entertain another internet-scale technological change.
Before long, the world will wake up. But right now, there are perhaps a few hundred people, most of them in San Francisco and the AI labs, that have situational awareness. Through whatever peculiar forces of fate, I have found myself amongst them. A few years ago, these people were derided as crazy—but they trusted the trendlines, which allowed them to correctly predict the AI advances of the past few years. Whether these people are also right about the next few years remains to be seen. But these are very smart people—the smartest people I have ever met—and they are the ones building this technology. Perhaps they will be an odd footnote in history, or perhaps they will go down in history like Szilard and Oppenheimer and Teller. If they are seeing the future even close to correctly, we are in for a wild ride.
Let me tell you what we see.
ViewShift: Hassle-free Dynamic Policy Enforcement for Every Data LakeWalaa Eldin Moustafa
Dynamic policy enforcement is becoming an increasingly important topic in today’s world where data privacy and compliance is a top priority for companies, individuals, and regulators alike. In these slides, we discuss how LinkedIn implements a powerful dynamic policy enforcement engine, called ViewShift, and integrates it within its data lake. We show the query engine architecture and how catalog implementations can automatically route table resolutions to compliance-enforcing SQL views. Such views have a set of very interesting properties: (1) They are auto-generated from declarative data annotations. (2) They respect user-level consent and preferences (3) They are context-aware, encoding a different set of transformations for different use cases (4) They are portable; while the SQL logic is only implemented in one SQL dialect, it is accessible in all engines.

Natural Language Processing (NLP), RAG and its applications .pptxfkyes25
1. In the realm of Natural Language Processing (NLP), knowledge-intensive tasks such as question answering, fact verification, and open-domain dialogue generation require the integration of vast and up-to-date information. Traditional neural models, though powerful, struggle with encoding all necessary knowledge within their parameters, leading to limitations in generalization and scalability. The paper "Retrieval-Augmented Generation for Knowledge-Intensive NLP Tasks" introduces RAG (Retrieval-Augmented Generation), a novel framework that synergizes retrieval mechanisms with generative models, enhancing performance by dynamically incorporating external knowledge during inference.

ABSTRACT
Our government spends substantial amount of resources in educating our
children. Additionally several welfare schemes are introduced aimed especially at
underprivileged children to ensure that all of them complete a basic level of
education. In spite of these measures many students do not complete their basic
education.
The aim of this project is to formulate a Supervised Learning Algorithm
that will aid in identifying such students who have a higher likelihood of not
completing their education.
To perform this task the algorithm will perform Logistic Regression
Analysis on historical data of students from a given school. The historical data
includes basic background information (features) such as gender, community,
number of siblings etc. It must be noted that the historical data also contains
information on whether the student completed his/her education, which is the
outcome we are interested in. Typically a student finishing education will be
denoted using a value of 1 and a student not finishing will be denoted with a value
of 0.
Based on the training (historical) data a logistic classifier can be built. Such
a classifier after learning from the training set will develop specific weightages for
each of the features. These weightages can then be extrapolated into an equation
that can be used for prediction.
That is we can apply the equation on a current student (whose background
we already know) to calculate the probability that he/she will complete his/her
education.
6. vi
Such an algorithm will be beneficial to government agencies since it can
serve as an early warning system using which they can take more proactive action
to prevent a student from dropping out. Policy makers can also use it as a tool to
identify schools that are more vulnerable and direct their resources and energies to
help them.

CHAPTER 1
INTRODUCTION
1.1 OVERVIEW OF THE PROJECT
Dropout is a universal phenomenon of the education system in India, which is
spread across all levels of education, in all parts of the country, and across socio-economic
groups the dropout rates are much higher for educationally backward
states and districts. Girls in India tend to have higher dropout rates than boys.
Similarly, children belonging to the socially disadvantaged groups like Scheduled
Castes and Scheduled Tribes have the higher dropout rates in comparison to the
general population.
There are also regional and location wise differences and the children living in
rural areas are more likely to drop out of school. In order to reduce wastage and
improve the efficiency of education system, educational planners need to
understand and identify the social groups that are more susceptible to dropout and
the reasons for their dropping out.
Keeping the above context in perspective, it would be helpful to develop a
system or an algorithm that can systematically identify such vulnerable students
who have a higher likelihood of dropping out from school. The goal of this project
is to develop such an algorithm or system.
Hopefully such an algorithm or system could assist educational planners and
administrative staff of educational institutions to better allocate resources and
make better decisions, which could curb this growing dropout problem.
16. 2
1.2 LITERATURE SURVEY
The literature survey covers existing research and studies with respect to the
dropout problem. They are grouped into three broad categories:
1 Research Papers
2 Surveys
3 Govt Reports
The detailed list of resources researched during the literature survey is
provided in the references section.
1.3 PROPOSED SYSTEM
The proposed system will implement an algorithm that will take in student
data as input and learn from it. This learned function, otherwise called as the
hypothesis will serve as an approximate explanation of the data. Error metrics and
validation techniques will be used to determine the accuracy of the hypothesis.
The best hypothesis that fits the data will then be used for prediction. The final
goal of the algorithm is to make reasonably accurate predictions of new unlabeled
data. Unlabeled data is data for which the outcome is unknown.
This system will be implemented in such a way that it can be operated from a
web interface where the user can upload datasets as well as make predictions
based on learned data.
1.4 SCOPE
17. 3
The algorithm developed is an exploratory proof – of – concept system that
uses machine learning and statistical techniques to make predictions based on
student data. The validity of the results is entirely dependent on the accuracy of
the data and how the algorithm processes it.
Since comprehensive student data was not available for making the algorithm
as best as possible, this iteration of the system can only serve as a proof – of –
concept on what is possible and cannot be directly used in the real world, in its
present form, as a decision making or policy making tool.

CHAPTER 2
REQUIREMENT SPECIFICATION
2.1 INTRODUCTION
A software requirements specification (SRS) defines the requirements of a
software system. It is a description of the behavior of a system to be developed
and may include a set of use cases. In addition it also contains non-functional
requirements. Non-functional requirements impose constraints on the design or
implementation (such as performance requirements, quality standards, or design
constraints).
This project requires storage and processing of medium to large volumes of
data/datasets. Such datasets will be passed through the algorithm initially during a
training phase, during this time the algorithm will learn using the training data.
After training is completed the algorithm would then be required to make
predictions for new unlabeled data based on what it learned from the training data.
Additionally it would be helpful it the algorithm can be operated from a
Web User Interface which will be more user friendly than issuing commands from
the command line.
2.2 OVERALL DESCRIPTION
This section will outline a holistic description of the project, which includes
different perspectives, constraints, functional and non – functional requirements of
the project.
19. 5
2.2.1 PRODUCT PERSPECTIVE
The system has 4 main tasks that are
Data Collection
Modeling
Validation
Prediction
In the data collection phase the data required for the
algorithm is gathered converted into a suitable form and supplied to
the system for learning.
In the modeling phase the algorithm tries to generate models
that try to explain the data that has been gathered. Machine Learning
techniques are used in this phase to generate multiple models of
which the best gets chosen in later stages.
In the validation phase the different models are evaluated
based on performance and the best among them is chosen as the
candidate algorithm that can be used for prediction
Finally in the prediction phase the chosen model is used for
making actual real world predictions.
2.2.2 PRODUCT FUNCTIONS
The system has two main functions that are
Training
20. 6
Prediction
In the training phase the dataset is supplied to the algorithm using
which the best model is developed for prediction
In the prediction phase the learnt algorithm can be actually put to
use that is it can be used to make predictions for unlabeled data.
How these processes are implemented is explained in detail in
subsequent sections.

CHAPTER 3
PROJECT REQUIREMENTS
The project requirement is to develop an algorithm that can classify
students on whether they would complete education or not (dropout). To achieve
this a system needs to be created that can be operated from a web user interface
that will supply data for training or can make predictions based on already trained
data.
3.1 SOFTWARE REQUIREMENTS
The software requirements for this project are:
R – R is a free software programming language and software
environment for statistical computing and graphics.
Node.js - Node.js is a cross-platform runtime environment and a
library for running applications written in JavaScript outside the
browser (for example, on the server)
Netbeans - NetBeans is an integrated development
environment (IDE) for developing primarily with Java, but also with
other languages, in particular PHP, C++, Node.js & HTML5

23. 9
CHAPTER 4
SYSTEM DESIGN
System design is the process of defining the architecture, components,
modules, interfaces and data for a system to satisfy specified requirements. System
design encompasses activities such as systems analysis, systems architecture and
systems engineering.
4.1 METHODOLOGY
A software development methodology or system development methodology
in software engineering is a framework that is used to structure, plan and control
the process of developing a software system.
This project consists of four distinct phases that are
Data Collection
Modeling
Validation
Prediction
4.2 ALGORITHM
The system will use a Logistic Regression Classifier, which is a Supervised
Machine Learning Algorithm. This algorithm will take student data as input and
predict an outcome. Outcomes are typically binary that is either a TRUE or
FALSE. A TRUE value indicates that a student will dropout while FALSE means
the student will not dropout.
24. 10
Since the algorithm will return only one of two possible outcomes it can
also be called as a binary/binomial classifier.
4.2.1 SUPERVISED LEARNING
Supervised learning is the machine-learning task of inferring a
function from labeled training data. The training data consist of a set of
training examples. Typically the training data for this project will consist of
data about students based on features that will be defined later in this
document.
In supervised learning, each example is a pair consisting of an input
object (typically a vector) and a desired output value (also called the
supervisory signal). A supervised learning algorithm analyzes the training
data and produces an inferred function, which can be used for mapping new
examples. New examples are usually unlabeled data that we need to predict.
An optimal scenario will allow for the algorithm to correctly determine the
class labels for unseen instances. This requires the learning algorithm to
generalize from the training data to unseen situations in a "reasonable" way.
In order to solve a given problem of supervised learning, the system
has to perform the following steps:
1. Determine the type of training examples : The kind of data that is
to be used as the training set needs to be determined first. In the case
of handwriting analysis, for example, this might be a single
handwritten character, an entire handwritten word, or an entire line
of handwriting
2. Gather a training set : The training set needs to be representative
of the real-world use of the function. Thus, a set of input objects is
25. 11
gathered and corresponding outputs are also gathered, either from
human experts or from measurements
3. Determine the input feature representation of the learned
function: The accuracy of the learned function depends strongly on
how the input object is represented. Typically, the input object is
transformed into a feature vector, which contains a number of
features that are descriptive of the object. The number of features
should not be too large; but should contain enough information to
accurately predict the output.
4. Determine the learning algorithm : The correct learning algorithm
that models the available data should be identified and applied. For
example the learning algorithm may be support vector machines or
decision trees
5. Complete the design : Run the learning algorithm on the gathered
training set. Some supervised learning algorithms require certain
control parameters. These parameters may be adjusted by optimizing
performance on a subset (called a validation set) of the training set,
or via cross-validation.
6. Evaluate the accuracy of the learned function : After parameter
adjustment and learning, the performance of the resulting function
should be measured on a test set that is separate from the training
set.
4.2.2 CLASSIFICATION
In machine learning and statistics, classification is the problem of
identifying to which of a set of categories (sub-populations) a new
observation belongs, on the basis of a training set of data containing
observations (or instances) whose category membership is known. The
26. 12
individual observations are analyzed into a set of quantifiable properties,
known as various explanatory variables, features, etc. These properties may
variously be categorical (e.g. "A", "B", "AB" or "O", for blood type),
ordinal (e.g. "large", "medium" or "small"), integer-valued (e.g. the number
of occurrences of a part word in an email) or real-valued (e.g. a
measurement of blood pressure). Some algorithms work only in terms of
discrete data and require that real-valued or integer-valued data be
discretized into groups (e.g. less than 5, between 5 and 10, or greater than
10). An example would be assigning a given email into "spam" or "non-spam"
classes or assigning a diagnosis to a given patient as described by
observed characteristics of the patient (gender, blood pressure, presence or
absence of certain symptoms, etc.).
An algorithm that implements classification, especially in a concrete
implementation, is known as a classifier. The term "classifier" sometimes
also refers to the mathematical function, implemented by a classification
algorithm, that maps input data to a category.
In the terminology of machine learning, classification is considered
an instance of supervised learning, i.e. learning where a training set of
correctly identified observations is available. The corresponding
unsupervised procedure is known as clustering or cluster analysis, and
involves grouping data into categories based on some measure of inherent
similarity (e.g. the distance between instances, considered as vectors in a
multi-dimensional vector space).
In statistics, where classification is often done with logistic
regression or a similar procedure, the properties of observations are termed
explanatory variables (or independent variables, regressors, etc.), and the
27. 13
categories to be predicted are known as outcomes, which are considered to
be possible values of the dependent variable. In machine learning, the
observations are often known as instances, the explanatory variables are
termed features (grouped into a feature vector), and the possible categories
to be predicted are classes. There is also some argument over whether
classification methods that do not involve a statistical model can be
considered "statistical".
4.2.3 LOGISTIC REGRESSION
In statistics, logistic regression, or logit regression, is a type of
probabilistic statistical classification model. It is also used to predict a
binary response from a binary predictor, used for predicting the outcome of
a categorical dependent variable (i.e., a class label) based on one or more
predictor variables (features). That is, it is used in estimating the parameters
of a qualitative response model. The probabilities describing the possible
outcomes of a single trial are modeled, as a function of the explanatory
(predictor) variables, using a logistic function. Logistic Regression is used
to refer specifically to the problem in which the dependent variable is
binary—that is, the number of available categories is two, while problems
with more than two categories are referred to as multinomial logistic
regression.
Logistic regression measures the relationship between a categorical
dependent variable and one or more independent variables, which are
usually (but not necessarily) continuous, by using probability scores as the
predicted values of the dependent variable.

where :
F(x) is the output

e is Euler’s number
It must be noted that 퐹(푥) can have a value only between 0 to 1 for
any value of x that may be between (−∞, ∞) . Using the above equation we
can define a value 푘 휖 (0, 1) such that all values of 퐹(푥) ≥ 푘 is true while
those lesser are false or vice versa, thereby classifying the data into two
distinct parts.

4.3 DATA COLLECTION
4.3.1 FEATURE DETECTION
Based on the literature survey six features have been identified as
major observable factors that can affect the final outcome regarding the
education fulfillment of a student.
The six features can be grouped into three categories that are:
1. Personal Features
2. Environmental Features
3. School Features
4.3.1.1 PERSONAL
Personal features are those features that are based on the
characteristics of the student or his/her parents, family background
etc. The personal features that are being considered by the algorithm
are:
1. Gender: Values can be Male or Female
2. Poverty: Values can be Yes or No
3. Community: Values can be General, OBC, SC, ST
4.3.1.2 ENVIRONMENTAL
Environmental features are those features that are based on
the student’s environment, locality, geography etc. The
30. 16
environmental features that are being considered by the algorithm
are:
1. Rural: Values can be Yes or No
4.3.1.3 SCHOOL
School features are those features that are based on the
characteristics of the school where the student studies. The school
features that are being considered by the algorithm are:
Pupil Teacher Ratio: Pupil–teacher ratio is the number of students
who attend a school or university divided by the number of teachers
in the institution. For example, a pupil–teacher ratio of 10:1
indicates that there are 10 students for every one teacher. The term
can also be reversed to create a teacher–pupil ratio.
Student Classroom Ratio: Student – classroom ratio is the number
of students per classroom in an education institution. For example, a
student – classroom ratio of 40:1 indicates that there are 40 students
for every classroom.
1. Pupil Teacher Ratio: Values can be Low (1 Teacher :
<30 Students), Medium (1 Teacher : 30 – 40 Students) and
High (1 Teacher : 40+ Students)
2. Student Classroom Ratio: Values can be Low (1
Classroom : <30 Students), Medium (1 Classroom: 30 –
40 Students) and High (1 Classroom: 40+ Students)
4.3.2 DATASET GENERATION

Based on statistics derived from the literature survey and the features
mentioned above the dataset for modeling is generated. The tables given
below extrapolate statistical findings compiled from the literature survey:
Feature Value Distribution Dropout Chance
Gender Male 52% 39%
Gender Female 48% 41%
Poverty Yes 22% 80%
Poverty No 78% 27%
Rural Yes 75% 45%
Rural No 25% 20%
Community General 30% 10%
Community OBC 40% 48%
Community SC 20% 64%
Community ST 10% 69%
PTR Low 20% 15%
PTR Medium 30% 35%
PTR High 50% 55%
SCR Low 18% 22%
SCR Medium 33% 25%
SCR High 49% 60%
Table 4.1 : Sample Dataset
The above table shows the distribution of each feature in the student
population and the corresponding dropout chance of each feature within
that population. For example when considering 100 students there are 52
32. 18
male students and 42 female students and the chance that a female student
drops out is 41%.
Overall Dropout Percentage was found to be 40%. That is 40% of
the student population dropout of school. Using the above statistics a
dataset can be generated for further analysis.

4.4 MODELING
Data modeling in software engineering is the process of creating a data
model for an information system by applying formal data modeling techniques.
33. 19
Fig 4.3 : Modeling
4.4.1 HYPOTHESIS DEVELOPMENT
A Hypothesis (plural hypotheses) is a proposed explanation for a
phenomenon. A working hypothesis is a provisionally accepted hypothesis
proposed for further research. In the context of Machine Learning the
hypotheses is also called as the Learned Function.
In the context of this project the learned function is a working
hypothesis that tries to explain the training dataset of students. Based on the
observations/outcomes of the training dataset the learned algorithm will
develop weightages for each of the features that have been selected. These
weightages will then be used for predicting outcomes in a future dataset.
4.4.2 GENERALIZATION ERROR
The generalization error of a machine-learning model is a function
that measures how well a learning machine generalizes to unseen data. It is
34. 20
measured as the distance between the error on the training set and the test
set and is averaged over the entire set of possible training data that can be
generated after each iteration of the learning process. It has this name
because this function indicates the capacity of a machine that learns with
the specified algorithm to infer a rule (or generalize).
The theoretical model assumes a probability distribution of the
examples, and a function giving the exact target. The model can also
include noise in the example (in the input and/or target output). The
generalization error is usually defined as the expected value of the square of
the difference between the learned function and the exact target (mean-square
error)
The performance of a machine learning algorithm is measured by
plots of the generalization error values through the learning process and are
called learning curves.
4.5 VALIDATION
In statistics, model validation is the process of deciding whether the
numerical results quantifying hypothesized relationships between variables,
obtained from machine learning analysis, are in fact acceptable as descriptions of
the data.
The validation process can involve analyzing the goodness of fit of the
model, analyzing whether the model residuals are random, and checking whether
the model's predictive performance deteriorates substantially when applied to data
that were not used in model estimation.
35. 21
4.5.1 DATASET PARTITIONING
In model validation for assessing the results of statistical analysis the
dataset is generally partitioned into two separate datasets. They are :
1. Training Dataset
2. Cross – Validation(CV) Dataset
The model is typically trained on the training dataset and then tested
on the cross – validation dataset that contains examples that are
independent of the training data. The actual training, cross – validation split
is upto the person doing the analysis. Usually ranges between 80-20%
(training – cv) or 70-30% is preferred so that the model has enough
examples for training the model.
Fig 4.4 : Dataset Partitioning
4.5.1.1 TRAINING DATASET
36. 22
A training set is a set of data used in various areas of
information science to discover potentially predictive relationships.
Training sets are used in artificial intelligence, machine learning,
genetic programming, intelligent systems, and statistics. In all these
fields, a training set has much the same role and is often used in
conjunction with a test set.
Fig 4.5 : Developing Multiple Models
4.5.1.2 CV DATASET
Cross-validation, sometimes called rotation estimation, is a
model validation technique for assessing how the results of a
statistical analysis will generalize to an independent data set. It is
mainly used in settings where the goal is prediction, and one wants
to estimate how accurately a predictive model will perform in
practice. In a prediction problem, a model is usually given a dataset
of known data on which training is run (training dataset), and a
dataset of unknown data (or first seen data) against which the model
is tested (testing dataset). The goal of cross validation is to define a
37. 23
dataset to "test" the model in the training phase (i.e., the validation
dataset), in order to limit problems like overfitting, give an insight
on how the model will generalize to an independent data set (i.e., an
unknown dataset, for instance from a real problem), etc.
One round of cross-validation involves partitioning a sample
of data into complementary subsets, performing the analysis on one
subset (called the training set), and validating the analysis on the
other subset (called the validation set or testing set). To reduce
variability, multiple rounds of cross-validation are performed using
different partitions, and the validation results are averaged over the
rounds.

4.5.2 COST FUNCTION
In mathematical optimization, statistics, decision theory and machine
learning, a cost function or loss function is a function that maps an event or
values of one or more variables onto a real number intuitively representing
38. 24
some "cost" associated with the event. An optimization problem seeks to
minimize a loss function. An objective function is either a loss function or
its negative (sometimes called a reward function or a utility function), in
which case it is to be maximized.
In statistics, typically a loss function is used for parameter
estimation, and the event in question is some function of the difference
between estimated and true values for an instance of data.
The cost function is expressed as :
퐽(휃) =
1
2푚
푚
Σ(ℎ휃 (푥(푖)) − 푦(푖))2
푖=1
Eq 4.2 : Cost Function or Error Function
where :
J is the Cost
m is the number of training examples
h(x) is the hypothesis
y is the actual value or the result vector
4.5.3 ERROR METRICS
Error metrics are systematic benchmarking measures that are used
for calculating the accuracy or effectiveness of the system. The cost
function is described above is a good example of an error metric. The
following error metrics are used for validation of the generated models and
in choosing the best among them:
39. 25
Training and CV Error
F1 Score
W – Score
4.5.3.1 TRAINING AND CV ERROR
Training error is cost function error of the trained model on
the training set. That is after training the model the training dataset is
supplied again to the model as input to make predictions. These
predictions made by the model are compared against the actual
outcomes in the dataset and the error between the two is calculated
using the cost function formula. The resulting value is the cost
function error.
The cross – validation error is similar to the training error
except it is calculated on the cross – validation set. The benefit here
is that the cross – validation set is new data and has none of the
training examples of the training set and thus can be a better estimate
of the accuracy of the system. Ideally the system’s cross – validation
error should be similar to the training error in which case the model
is a good estimate of the underlying data.
4.5.3.2 F1 Score
In statistical analysis of binary classification, the F1 score
(also F-score or F-measure) is a measure of a test's accuracy. It
considers both the precision p and the recall r of the test to compute
the score: p is the number of correct results divided by the number of
all returned results and r is the number of correct results divided by
40. 26
the number of results that should have been returned. The F1 score
can be interpreted as a weighted average of the precision and recall,
where an F1 score reaches its best value at 1 and worst score at 0.

4.5.3.3 W – Score
The W-Score is a combination of the training, cross
validation errors using which the best model gets chosen. The best
model that gets chosen will have the least W – Score. The W – Score
is expressed as :
푊 = (1 − 푓1).

4.5.4 LEARNING CURVES
Fig 4.7 : Single Subject Learning Fig 4.8 : Learning from Experience
Fig 4.9 : Score & Learning Time vs Experience
42. 28
A learning curve is a graphical representation of the increase of learning
(vertical axis) with experience (horizontal axis). Although the curve for a single
subject may be erratic (Fig 4.7), when a large number of trials are averaged, a
smooth curve results, which can be described with a mathematical function (Fig
4.8). Depending on the metric used for learning (or proficiency) the curve can
either rise or fall with experience (Fig 4.9).
Within the context of the project the horizontal axis will be training
examples, which is basically derived from experience, and the vertical axis is the
cost function error. Ideally the cost function error should decrease with increase in
training examples.
But there are two types of errors, that is the training error and the cross –
validation error. With increase in training examples the training error would
increase gradually so as to prevent overfitting and since the training dataset has to
explain a diverse spectrum of examples. But it should not increase exponentially.
Also if the model is efficient then it should perform just as good on new data as it
does on the training dataset. So the cross – validation error must decrease with
increase in training examples.
Thus the ideal model will have a small increase in training error with
increase in training examples and the cross – validation error should decrease with
increase in training examples and the two errors must converge as shown in (Fig
4.10).

Fig 4.11 : Choosing the Best Model
4.6 PREDICTION
Prediction is the final step in the process. After selecting the best model that
fits the given dataset the model can be put to use on actual real world unlabeled
data. That is it can be used to predict data for which the outcomes are not known.
44. 30
The prediction process begins with the algorithm being supplied unlabeled student
data using which it predicts an outcome, which is whether the student will dropout
or not.

k = 1;
for(i in p){
if(r <= i){
break;
}
k = k + 1;
}
return(k);
}
#Generate Vector
result <- factor(list$data);
for(i in 1:n) {
index <- getIndex(p, runif(1));
value <- list$data[index];
result[i] = value;
}

CONCLUSIONS
The advent of Information Technology and the Internet has lead to vast
amounts of data being gathered and stored in multiple formats by multiple sources.
Thus both big corporations as well as Government Agencies are attempting to tap
into these vast troves of data for making better decisions and creating eff icient
processes. Several techniques such as Machine Learning, Neural Networks etc,
which are commonly termed as Big Data, are trying to revolutionize the way we
analyze information and are adding real value.
This project was inspired by such technologies. The aim was to create an
objective mechanism for solving the dropout problem that could be used for policy
making. This algorithm could provide an objective solution by identifying
vulnerable students who truly need help and thereby improve retention and
completion rates in schools.
Personally, it was a great opportunity for me to discover an area of
programming that I had wanted to learn for some time now. At the same time
getting a chance to solve a real world problem that is vital to our society made it
all the more worthwhile. I humbly admit that the algorithm developed is in no way
perfect but it was a determined attempt from my end to prove what is possible.
Hopefully people after me would take this up and extend it to such a point that it
can be of use to Government Agencies and provide real value to students who are
the final beneficiaries of this system and the future of our nation.
