NPTEL IITKGP Introduction to Machine Learning

ABOUT THE COURSE :

This course provides a concise introduction to the fundamental concepts in 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.

This course can have Associate in Nursing unproctored programming communication conjointly excluding the Proctored communication, please check announcement section for date and time. The programming communication can have a weightage of twenty fifth towards the ultimate score.

Final score = Assignment score + Unproctored programming exam score + Proctored Exam score
  • Assignment score = 25% of average of best 8 assignments out of the total 12 assignments given in the course.
  • ( All assignments in a particular week will be counted towards final scoring – quizzes and programming assignments). 
  • Unproctored programming exam score = 25% of the average scores obtained as part of Unproctored programming exam – out of 100
  • Proctored Exam score =50% of the proctored certification exam score out of 100
YOU WILL BE ELIGIBLE FOR A CERTIFICATE ONLY IF ASSIGNMENT SCORE >=10/25 AND
UNPROCTORED PROGRAMMING EXAM SCORE >=10/25 AND PROCTORED EXAM SCORE >= 20/50. 
If any one of the 3 criteria is not met, you will not be eligible for the certificate even if the Final score >= 40/100.

2. In AdaBoost, we give more weights to ponts having been misclassified in previous iterations. Now, if we introduced a limit or cap on the weight that any point can take (for example, say we introduce a restriction that prevents any point’s weight from exceeding a value of 10). Which among the following would be an effect of such a modification?

A) We nmay observe the performance of the classıfier reduce as the number of stagesincrease.
B) It makes the final classifier robust to outliers.
C) It may result in lower overall performance.
D) None of these.

3. Which among the following are some of the differences between bagging and boosting?

A) In bagging we use the same classification algorithm for training on each sample of the data, whereas in boosting, we use different classification algorithms on the different training data samples.
B) Bagging 1s easy to parallelize whereas boosting 1s inherently a sequential process.
C) In bagging we typically use sampling with replacement whereas in boosting, we typically use weighted sampling techniques.
D) In comparison with the performance of a base classifier on a particular dataset, bagging will generally not increase the error whereas as boosting may leadto an increase in the error.

Answer:- b, c, d
4. What is the VC-dimension of the class of sphere in a 3-dimensional plane?

A) 3
B) 4
C) 5
D) 6

Answer:- a
5. Considering the AdaBoost algorithm, which among the following statements is true?

A)In each stage, we try to train a classifier which makes accurate predictions on anysubset of the data points where the subset size is at least half the size of the data et.
B) In each stage, we try to tran a classifier which makes accurate predictions on a subset of the data points where the subset contains more of the data points whichwere misclassified in earlier stages.
C) The weight assigned to an undividual classifier depends upon the number of data points correctly classified by the classifier.
D) The weight assigned to an individual classifier depends upon the weighted sumerror of misclassified ponts for that classifier.

Answer:- b, d
