Hi all,
I have a LogisticRegression model I'm training in a 3-class scenario. I'd
like to examine the coefficients for the models. As the default for
LogisitcRegression is to do one-vs-all classification, my clf.coef_ array
is shape 3 x nfeat.
My question is how to interpret the sign of the coefficients. I take each
nfeat vector to be the coefficients for the A vs all, B vs all, C vs all
models. In this case, are positive coefficients in the first nfeat vector
those weighing the classification towards "A" and the negative coefficients
those weighing the model towads "all"? Or is it the other way around?
Cheers,
Michael
