**NPTEL Introduction To Machine Learning – IITKGP Assignment 6 Answers 2022 [July-Dec]**:- In this post, We have provided answers to NPTEL Introduction to Machine Learning – IITKGP Assignment 6 Week 6. We provided answers here only for reference. Please, do your assignment to your own knowledge.

## About Introduction To Machine Learning – IITKGP

This course provides a concise introduction to the fundamental concepts of machine learning and popular machine learning algorithms. We will cover the standard and most popular supervised learning algorithms including linear regression, logistic regression, decision trees, k-nearest neighbour, an introduction to Bayesian learning and the naïve Bayes algorithm, support vector machines and kernels and neural networks with an introduction to Deep Learning. We will also cover the basic clustering algorithms. Feature reduction methods will also be discussed.

We will introduce the basics of computational learning theory. In the course, we will discuss various issues related to the application of machine learning algorithms. We will discuss hypothesis space, overfitting, bias and variance, tradeoffs between representational power and learnability, evaluation strategies and cross-validation. The course will be accompanied by hands-on problem-solving with programming in Python and some tutorial sessions.**CRITERIA TO GET A CERTIFICATE**

Average assignment score = 25% of the average of the best 6 assignments out of the total 8 assignments given in the course.

Exam score = 75% of the proctored certification exam score out of 100

Final score = Average assignment score + Exam score

YOU WILL BE ELIGIBLE FOR A CERTIFICATE ONLY IF YOUR AVERAGE ASSIGNMENT SCORE >=10/25 AND YOUR

**EXAM SCORE >= 30/75. If one of the 2 criteria is not met, you will not get the certificate even if the Final score >= 40/100.**
