a) Tom has a dataset regarding housing in San Antonio. This set of data contains one thousand features. Tom aims to use fewer features in his regression model. He plans on using ridge regression in orderto identify which are the important features and which are not. Is this a correct or incorrect practice? b) Harold knows that it is very time-consuming to find the best subset of features for a regression model. He chooses to implement the forward stepwise algorithm, considerably decreasing the runtime without compromising on finding a good enough set of features. Is this a correct or incorrect practice
