[scikit-learn] Project Contribution

2018-05-02 Thread prince jha
Hello everyone, I am also willing to contribute to scikit-learn open source project but since I have never contributed to any open-source projects earlier, so I don't have any idea regarding where to start from. So I will be thankful if any of you could help me in this so that I could also start co

By the linear nature of the problem the targets are always separately treated (even if there was a matrix-variate normal prior indicating covariance between target columns, you could do that adjustment before or after fitting). As for different alpha parameters, I think you can specify a different

Thanks, Bertrand - very helpful. Needed to consolidate this. Peter On 2 May 2018 at 13:07, bthirion wrote: > The alpha parameter is shared for all problems; If you wnat to use > differnt parameters, you probably want to perform seprate fits. > Best, > > Bertrand > > On 02/05/2018 13:08, Peer No

Hi all, I am struggling to understand the following: Scikit-learn offers a multiple output version for Ridge Regression, simply by handing over a 2D array [n_samples, n_targets], but how is it implemented? http://scikit-learn.org/stable/modules/generated/sklearn.linear_model.Ridge.html Is it co
