LassoNet-Unsupervised Feature Selection

zhangyunz opened this issue a year ago · comments

Hi,

I would like to use lassonet as an unsupervised feature selection algorithm, and I have made some attempts. However, it seems that I didn't get the correct outcome.

My use case:

I have an input matrix without labels, and I want to have a new reduced matrix with only several important features. I also want to know which features have been selected.

Hi, what is the problem? If it is that the number of features decreases too fast, you could try a smaller path_multiplier.
