WitrynaLogistic regression with built-in cross validation. Notes The underlying C implementation uses a random number generator to select features when fitting the model. It is thus not uncommon, to have slightly different results for the same input data. If that happens, try with a smaller tol parameter. WitrynaLogistic regression is a binary classifier. Logistic regression is the application of a logit function on the output of a usual regression approach. Logit function turns $(-\infty, +\infty)$ to $[0,1]$. I think it is just for historical reasons that it keeps that name. Saying something like "I did some regression to classify images.
