What is the purpose of fitting a classifier in regression training and testing?

Monday, 07 August 2023 by EITCA Academy

Fitting a classifier in regression training and testing serves a important purpose in the field of Artificial Intelligence and Machine Learning. The primary objective of regression is to predict continuous numerical values based on input features. However, there are scenarios where we need to classify the data into discrete categories rather than predicting continuous values.
