make_classification question
by Anna Jenul Aug. 12, 2020

Aug. 12, 2020

Hi! I am generating own datasets with sklearn.datasets.make_classification. Unfortunately, I cannot figure out which of the generated features are the informative ones. In my example I generate "n_features=1000" and "n_informative=20". Is there any possibility to get the informative features after the dataset is generated? Thanks, Anna

Tikhonov regularization
by David Kleiven Aug. 12, 2020

Aug. 12, 2020

Hi, I was looking at docs for Ridge regression and it states that it minimizes ||y - Xw||^2 + alpha*||w||^2 I would like to minimize the function ||y-Xw||^2 + ||Tx||^2, where T is a matrix, in order to impose certain properties on the solution vectors, but I haven't found any way to achieve that in scikit-learn. Is this type of regularisation supported in scikit-learn? More details on the ||Tx||^2 regularisation can be found here https://en.wikipedia.org/wiki/Tikhonov_regularization Best, David
