Description:
Quite often, when performing classification, we must deal with data (target/label) variable where the classes defined are lobsided e.g. out of 100 credit card transactions we might have 99 transactions that are not fraudulent, and only 1 transaction is fraudulent.

Course Outline:
Quite often, when performing classification, we must deal with data (target/label) variable where the classes defined are lobsided e.g. out of 100 credit card transactions we might have 99 transactions that are not fraudulent, and only 1 transaction is fraudulent. Models built using such data might give great accuracy – but is that model great? How can we handle such an imbalanced dataset? In this session, we are going to learn different techniques to generate synthetic data to overcome such imbalances.
We will perform hands-on labs to understand the following:
Training Material provided: Yes (Digital format)
Hands-on Lab: Labs will be performed using Google Colaboratory (or on personal machine)
