I did a quick search for a neural network analysis tool for pytorch, but did not find much.
To start of I want to compare the importance of input variables for the test result. Later on I might want to do more, but this is what I want to start with.
Is it a function, feature, or tool - with Pytorch thank can help me find the importance of input variables of the NN?
Or is it better to use PCA, Boosted Tree algorithm, etc. - before hand - to find the importance of variables?
