In a world of data explosion, the rate of data generation and consumption is on the increasing side, there comes the buzzword - Big Data.
Big Data is the concept of fast-moving, large-volume data in varying dimensions (sources) and
highly unpredicted sources.
The 4Vs of Big Data
● Volume - Scale of Data
● Velocity - Analysis of Streaming Data
● Variety - Different forms of Data
● Veracity - Uncertainty of Data
With increasing data availability, the new trend in the industry demands not just data collection,
but making ample sense of acquired data - thereby, the concept of Data Analytics.
Taking it a step further to further make a futuristic prediction and realistic inferences - the concept
of Machine Learning.
A blend of both gives a robust analysis of data for the past, now and the future.
There is a thin line between data analytics and Machine learning which becomes very obvious
when you dig deep.
This document discusses classification and prediction techniques for data analysis. Classification predicts categorical labels, while prediction models continuous values. Common algorithms include decision tree induction and Naive Bayesian classification. Decision trees use measures like information gain to build classifiers by recursively partitioning training data. Naive Bayesian classifiers apply Bayes' theorem to estimate probabilities for classification. Both approaches are popular due to their accuracy, speed and interpretability.

Study and Analysis of K-Means Clustering Algorithm Using RapidminerIJERA Editor
Institution is a place where teacher explains and student just understands and learns the lesson. Every student has his own definition for toughness and easiness and there isn’t any absolute scale for measuring knowledge but examination score indicate the performance of student. In this case study, knowledge of data mining is combined with educational strategies to improve students’ performance. Generally, data mining (sometimes called data or knowledge discovery) is the process of analysing data from different perspectives and summarizing it into useful information. Data mining software is one of a number of analytical tools for data. It allows users to analyse data from many different dimensions or angles, categorize it, and summarize the relationships identified. Technically, data mining is the process of finding correlations or patterns among dozens of fields in large relational database. Cluster analysis or clustering is the task of grouping a set of objects in such a way that objects in the same group (called a cluster) are more similar (in some sense or another) to each other than to those in other groups (clusters).This project describes the use of clustering data mining technique to improve the efficiency of academic performance in the educational institutions .In this project, a live experiment was conducted on students .By conducting an exam on students of computer science major using MOODLE(LMS) and analysing that data generated using RapidMiner(Datamining Software) and later by performing clustering on the data. This method helps to identify the students who need special advising or counselling by the teacher to give high quality of education.
Supervised learning is a machine learning approach that's defined by its use of labeled datasets. These datasets are designed to train or “supervise” algorithms into classifying data or predicting outcomes accurately.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UPRAHUL
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

24. Supervised Learning:-Learning from the
known label data to create a model then
predicting target class for the given input
data
25.
26. 1. Linear regression & multiple linear
regression
2. Logistic Regression
3. Polynomial Regression
4. Decision trees
5. Support Vector Machine(SVM)
6. K-nearest Neighbors (KNN)
7. Naive Bays
8. Random Forest
27. It is a basic and commonly used type of
Predictive analysis .The relationship between
variable (Y) and one or more independent
variable.
Simple Linear Regression:- There is only one
input variable (x).
Multiple Linear Regression :- There are
input variables (e.g. x1, x2, etc.) then this
would be called multiple regression.
28. It is called the sigmoid function was
developed by statisticians to describe
properties of population growth in ecology,
rising quickly and maxing out at the carrying
capacity of the environment.
It is used to find the Probability of event
success and event failure.
29. Minimized in the same way as linear
regression
For example cubic fit with one feature x:
h()=+x+x2+x3
Generate new feature by squaring cubing the
original feature
30. It is mostly used in classification.
Types of Decision tree:-
1. Categorical variable decision tree:- It has
categorical target variable then it called as
categorical .
2. Continuous variable decision tree:- It has
continuous target variable then it is called as
variable decesion tree.
31. Easy to understand
Useful in data exploration
Less data cleaning required
Data type is not constraint
Non parametric method
32. It is supervised learning algorithm.
It is mostly used for classification problems
There are two types classifiers
1. Linear svm
2. Non linear svm
33. In linear svm the data points are separated by
an apparent gap.
It predicts a straight hyper plane dividing 2
classes.
The hyper plane is called as a maximum
margin hyper plane
34. In non linear svm data points plotted in
higher dimensional space .
Here kernel trick used for maximum margin
hyper plane.
35. Allows use of relatively small parameter
algorithms to redirect a chaotic system to the
target.
Reduces waiting time for chaotic systems.
Maintains the performance of systems.

Generalized predictive control(GPC)
37. It is used for both classification and
regression predictive problems.
It widely used in classification industry.
It is to predict the target label by finding the
nearest neighbor class . The closest class will
be identified using the distance measures like
Euclidean distance.
38. By using cross validation technique we can
test KNN algorithm with Different Values of K.
A small value of K means that noise will have
higher influence on the result i.e the
probability of over fitting is very high.
A large value of K makes it computationally
expensive and defeats the basic idea behind.
39. KNN classifier is very simple classifier that
works well on basic recognition problems.
40. It is a straight forward and powerful
algorithm for the classification task.
It works on Bayes theorem of probability to
predict the class of unknown data set.
It is applicable for discrete data.
41. It is used for continuous values.
In this classifier continuous values associated
with each feature are assumed to be
distributed according to a Gaussian
Distribution and it also called normal
distribution.
It gives a bell shaped curve which symmetric
about mean if the featured values.
42. It is used for both classification and
regression kind of problem.
This algorithm creates the forest with a
number of decision trees.
More trees in the forest the more robust the
forest looks like .Like this the higher the
number of trees in the forest gives the high
accuracy results.
44. Example: decision trees tools that create
rules
Prediction of future cases: Use the rule to
predict the output for future inputs
Knowledge extraction: The rule is easy to
understand
Compression: The rule is simpler than the
data it explains
Outlier detection: Exceptions that are not
covered by the rule, e.g., fraud
45. Unsupervised Learning:- Learning from the
known unlabeled data to differentiating the
given input data.
46. Learning “what normally happens”
No output
Clustering: Grouping similar instances
Other applications: Summarization,
Association Analysis
Example applications
◦ Customer segmentation in CRM
◦ Image compression: Color quantization
◦ Bioinformatics: Learning motifs

Getting ready
Step 1 - collecting and describing data
Step 2 - exploring data
Step 3 - data cleaning
Step 4 - visualizing cleaned data
Step 5 - building the model and visualizing it
52. It is unsupervised learning , which is used
when you have unlabeled data.
The goal of this algorithm is to find groups
in the data ,with the number of groups
represented by the variable K.
The centroids of the K clusters , which can
be label new data
53. Assuming we have inputs X1,X2,X3……Xn
and value of K
Step-1:-Pick random points as cluster centers
called centroids
Step-2:-Assign each xi to nearest cluster by
calculating its distance to each other.
Step-3:-Find new cluster center by taking the
average of the assigned points.
Step-4:-Repeat step-2 and step-3 until none
of the cluster assignments change.

55. Hierarchical clustering is a widely used data
analysis tool.
The idea is to build a binary tree of the data
that successively merges similar groups of
points.
Visualizing this tree provides a useful
summary of the data.
Hierarchical clustering only requires a
measure of similarity between groups of
data points.
56.
57. 1. Let X = {x1, x2, x3, ..., xn} be the set of data points.
2. Begin with the disjoint clustering having level L(0) = 0 and
sequence number m = 0.
3. Find the least distance pair of clusters in the current clustering,
say pair (r), (s), according to d[(r),(s)] = min d[(i),(j)] where the
minimum is over all pairs of clusters in the current clustering.
4. Increment the sequence number: m = m +1.Merge clusters (r)
and (s) into a single cluster to form the next clustering m. Set
the level of this clustering to L(m) = d[(r),(s)].
5. Update the distance matrix, D, by deleting the rows and
columns corresponding to clusters (r) and (s) and adding a row
and column corresponding to the newly formed cluster. The
distance between the new cluster, denoted (r,s) and old
cluster(k) is defined in this way: d[(k), (r,s)] = min (d[(k),(r)],
d[(k),(s)]).
6. If all the data points are in one cluster then stop, else repeat
from step 2).Divisive Hierarchical clustering - It is just the
reverse of Agglomerative Hierarchical approach.
58.
59. 1) No a prior information about the number
of clusters required.
2) Easy to implement and gives best result in
some cases.
60. 1. Algorithm can never undo what was done previously.
2. Time complexity of at least O(n2 log n) is required,
where ‘n’ is the number of data points.
3. Based on the type of distance matrix chosen for
merging different algorithms can suffer with one or
more of the following:
4. i) Sensitivity to noise and outliers
5. ii) Breaking large clusters
6. iii) Difficulty handling different sized clusters and
convex shapes
7. No objective function is directly minimized
8. Sometimes it is difficult to identify the correct
number of clusters by the dendrogram.
61.
62. Labeled data is used to help identify that there are
specific groups of webpage types present in the
data .
The algorithm is then trained on unlabeled data to
define the boundaries of those webpage types and
may even identify new types of webpages that
were unspecified in the existing human-inputted
labels.
Semi-supervised learning falls
between unsupervised learning (without any
labeled training data) and supervise learning (with
completely labeled training data).

65. In reinforcement learning, the learner is a decision-
making agent that takes actions in an environment
and receives reward (or penalty)for its actions in
trying to solve a problem.
After a set of trial-and error runs, it should learn the
best policy, which is the sequence of actions that
maximize the total reward.
66. Topics:
◦ Policies: what actions should an agent take in a particular
situation
◦ Utility estimation: how good is a state (used by policy)
No supervised output but delayed reward
Credit assignment problem (what was responsible for
the outcome)
Applications:
◦ Game playing
◦ Robot in a maze
◦ Multiple agents, partial observability, ...
