WebSep 4, 2024 · The parameter ‘C’ of the Logistic Regression model affects the coefficients term. When regularization gets progressively looser or the value of ‘C’ decreases, we get more coefficient values as 0. One must keep in mind to keep the right value of ‘C’ to get the desired number of redundant features. A higher value of ‘C’ may ...
