Introduction
The Masters in Predictive Analytics program at Northwestern University offers
graduate courses that cover predictive modeling using several software products
such as SAS, R and Python. The Predict 410 course is one of the core courses and
this section focuses on using Python.
Predict 410 will follow a sequence in the assignments. The first assignment will ask
you to perform an EDA(See Ratner1 Chapters 1&2) for the Ames Housing Data
dataset to determine the best single variable model. It will be followed by an
assignment to expand to a multivariable model. Python software for boxplots,
scatterplots and more will help you identify the single variable. However, it is easy
to get lost in the programming and lose sight of the objective. Namely, which of
the variable choices best explain the variability in the response variable?
(You will need to be familiar with the data types and level of measurement. This
will be critical in determining the choice of when to use a dummy variable for model
building. If this topic is new to you review the definitions at Types of Data before
reading further.)
This report will help you become familiar with some of the tools for EDA and allow
you to interact with the data by using links to a software product, Shiny, that will
demonstrate and interact with you to produce various plots of the data. Shiny is
located on a cloud server and will allow you to make choices in looking at the plots
for the data. Study the plots carefully. This is your initial EDA tool and leads to
your model building and your overall understanding of predictive analytics.
Single Variable Linear Regression EDA

Top 40 Data Science Interview Questions and Answers 2022.pdfSuraj Kumar
1 – What is F1 score?
F1 score is a measure of the accuracy of a model. It is defined as the harmonic mean of precision and recall.
F1 score is one of the most popular metrics for assessing how well a machine learning algorithm performs on predicting a target variable. F1 score ranges from 0 to 1, with higher values indicating better performance.
The F1 score is used to evaluate the performance of a machine learning algorithm by considering how many times it has classified correctly and how many times it has misclassified.
The higher the F1 score, the better the performance of an algorithm.
2 – What is pickling and unpickling?
Pickling is the process of converting an object into a string representation. It can be used to store the object in a file, send it over a network, or save it to disk.
Unpickling is the inverse process of pickling. It converts an object from its string representation back into an object.
Pickling and unpickling can be done with machine learning by using an algorithm that converts the input to the output.
3 – Difference between likelihood and probability?
Probability is a measure of the likelihood of an event happening under certain conditions. The event can be a machine learning algorithm predicting the probability that a person will buy a product or not.
Likelihood is the probability that an event will happen, based on evidence and knowledge about the world. For example, if you see someone who looks like they are going to rob you and you know that they have robbed other people in the past, your likelihood of being robbed is high.
4 – Which machine learning algorithm known as a lazy learner?
KNN is a machine learning algorithm known as a lazy learner. K-NN is a lazy learner because it doesn’t learn any machine learnt values or variables from the training data but dynamically calculates distance every time it wants to classify, hence memorizes the training dataset instead.
5 – How to fix multicollinearity?
Multicollinearity is a statistical problem that arises when two or more independent variables are highly correlated.
One way to fix multicollinearity is to use a different variable that has less correlation with the other variables. If there are not any other variables available, one can use a transformation on the original variable and then re-run the regression.
6 – Significance of gamma and Regularization in SVM?
The significance of gamma and regularization in SVM is that they are used to control the trade-off between the training error and the generalization error. In other words, these two parameters are used to balance the bias-variance trade-off.
Regularization is a technique to reduce overfitting by penalizing models with more complexity than necessary. The goal of regularization is to find a model that has good generalization performance, which means it can correctly predict new data points with high accuracy. On the other hand, gamma is a parameter that controls how much weight should be given to each training ex

The document classification solution should significantly reduce the manual human effort in the HRM. It
should achieve a higher level of accuracy and automation with minimal human intervention
Abstract:
A resume is a brief summary of your skills and experience. Companies recruiters and HR teams have a tough time scanning
thousands of qualified resumes. Spending too many labor hours segregating candidates resume's manually is a waste of a
company's time, money, and productivity. Recruiters, therefore, use resume classification in order to streamline the resume
and applicant screening process. NLP technology allows recruiters to electronically gather, store, and organize large
quantities of resumes. Once acquired, the resume data can be easily searched through and analyzed.
Resumes are an ideal example of unstructured data. Since there is no widely accepted resume layout, each resume may have
its own style of formatting, different text blocks and different category titles. Building a resume classification and gathering
text from it is no easy task as there are so many kinds of layouts of resumes that you could imagine
3. I N T R O D U C T I O N :
In this project we dive into building a Machine learning model for Resume Classification using Python and basic Natural language
processing techniques. We would be using Python's libraries to implement various NLP (natural language processing) techniques like tokenization,
lemmatization, parts of speech tagging, etc.
A resume classification technology needs to be implemented in order to make it easy for the companies to process the huge number of
resumes that are received by the organizations. This technology converts an unstructured form of resume data into a structured data format. The
resumes received are in the form of documents from which the data needs to be extracted first such that the text can be classified or predicted based
on the requirements. A resume classification analyzes resume data and extracts the information into the machine readable output. It helps
automatically store, organize, and analyze the resume data to find out the candidate for the particular job position and requirements. This thus helps
the organizations eliminate the error-prone and time-consuming process of going through thousands of resumes manually and aids in improving the
recruiters’ efficiency.
The basic data analysis process is performed such as data collection, data cleaning, exploratory data analysis, data visualization,
and model building. The dataset consists of two columns, namely, Role Applied and Resume, where ‘role applied’ column is the domain field of
the industry and ‘resume’ column consists of the text extracted from the resume document for each domain and industry.
The aim of this project is achieved by performing the various data analytical methods and using the Machine Learning models and
Natural Language Processing which will help in classifying the categories of the resume and building the Resume Classification Model.

14. Text pre-processing includes converting to lowercase, removing spaces, html links, emails, symbols, numbers,
stop-words, tokenization and lemmatization.
Removing All Unwanted Character’s
Word Tokenization - Tokenization is essentially splitting a phrase, sentence, paragraph, or an entire text document into
smaller units, such as individual words or terms. Each of these smaller units are called tokens.
Removing Stop-words - A stop word is a commonly used word (such as “the”, “a”, “an”, “in”) that a search engine has been
programmed to ignore, both when indexing entries for searching and when retrieving them as the result of a search query.

Problems with imbalanced data classification
If explained it in a very simple manner, the main problem with imbalanceddataset prediction is how accurately are we actually predicting both
majorityand minority class?
•SMOTE: Synthetic Minority Oversampling Technique
SMOTE is an oversampling technique where the synthetic samples are generated for the minority class. This algorithm helps to
overcome the overfitting problem posed by random oversampling. It focuses on the feature space to generate new instances with
the help of interpolation between the positive instances that lie together.
30. T R A I N T E S T S P L I T :
Problems with Random Data Splitting
If explained it in a very simple manner, the main problem is random splitting the data the ratio of the classes does not reflect on training and
testing. Due to random splitting one class can be heavily sampled in training and creating majorityand minority class issue ( ImbalancedData)
which will give rise to bad scores on test data and overall performance and misclassification.
•Stratified Samling:
In stratifiedSampling the ratio of all the classes is maintained on both training and testing data thus this type of Split results in good accuracy
and overall model building performance.
31. F E A T U R E E N G I N E E R I N G :
Before Oversampling After Oversampling
Sometimes when the records of a certain class are much more than the other class, our classifier may get biased towards the
prediction. Thus our traditional approach of classification and model accuracy calculation is not useful in the case of the
imbalanced dataset
32. F E A T U R E E N G I N E E R I N G :
Sometimes when the records of a certain class are much more than the other class, our classifier may get biased towards the
prediction. In this case, the confusion matrix for the classification problem shows how well our model classifies the target
classes and we arrive at the accuracy of the model from the confusion matrix.
33. M O D E L B U I L D I N G :
If we do random sampling to split the dataset into training set and test set. Then we might get a
majority of one of the class in training and minority of other in testing. If we train our model
obviously we will be getting bad evaluation scores.
Stratified sampling is the solution to maintain the ratio of all classes in both training as well as in
testing data
34. M O D E L B U I L D I N G :
The solution for the first problem where we were able to get different accuracy scores for different
random state parameter values is to use K-Fold Cross-Validation. But K-Fold Cross Validation also
suffers from the second problem i.e. random sampling.
The solution for both the first and second problems is to use Stratified K-Fold Cross-Validation.
Stratified k-fold cross-validation is the same as just k-fold cross-validation, But Stratified k-fold cross-
validation, it does stratified sampling instead of random sampling.
