JAWAHARLAL NEHRU TECHNOLOGICAL UNIVERSITY HYDERABAD

Course Objective

The objective of this lab is to get an overview of the various machine learning

techniques and can able to demonstrate them using python.

Course Outcomes

After the completion of the course the student can able to:

• 1. understand complexity of Machine Learning algorithms and their limitations;
• 2. understand modern notions in data analysis-oriented computing;
• 3. be capable of confidently applying common Machine Learning algorithms in practice and implementing their own;
• 4. Be capable of performing experiments in Machine Learning using real-world data.

List of Experiments

• 1. The probability that it is Friday and that a student is absent is 3 %. Since there are 5 school days in a week, the probability that it is Friday is 20 %. What is theprobability that a student is absent given that today is Friday? Apply Baye’s rule in python to get the result. (Ans: 15%)
• 2. Extract the data from database using python
• 3. Implement k-nearest neighbours classification using python
• 4. Given the following data, which specify classifications for nine combinations of VAR1 and VAR2 predict a classification for a case where VAR1=0.906 and VAR2=0.606, using the result of k- means clustering with 3 means (i.e., 3 centroids) VAR1 VAR2 CLASS 1.713 1.586 0 0.180 1.786 1 0.353 1.240 1 0.940 1.566 0 1.486 0.759 1 1.266 1.106 0 1.540 0.419 1 0.459 1.799 1 0.773 0.186 1
