How to get intermediate alpha(a) when solving dual logistic regression

[Ouimoi]

Hi there, I am wondering how I can get the intermediate alpha(a) when solving dual logistic regression, with L2 regularizer for example.

I am using Python interface but it seems the output model doesn't contain alpha information anymore.
Really appreciate any kind of help here.

Yes the reason is the only the final model w vector is needed. I think you can print it if needed

Thank you for your prompt response. Then I will check if any parameter can be passed to print alpha or I need to build from modified source codes.

Hey @Ouimoi did you manage to print the alphas? Or could @cjlin1 point me to where I should modify the code to do so?

You can find them in linear.cpp and write them to disk.
