I think this is true to a great extent, and it motivates including standard techniques, where they are well-defined and tricky to DIY. I also think it is unfortunate to some extent, and we need to increasingly encourage users to think of scikit-learn as an API, and to help them find high-quality API compliant implementations. I don't think we're doing that enough yet.\r\n\r\nIf definition of these forward selection techniques is clear / relatively undisputed, I'd be okay to see them contributed.\r\n"}}
