Hi,
I’m trying to create a textual classifier. The goal is to categorize different sentences of a wikipedia page into a set of classes. I have 4 different classes which I named “other”,“eats”,“habitat” and “lifespan”. I was wondering how these labels can be turned into integers. I have a word to index dictionary that maps each word in my training wikipedia text to a unique index. Should I encode the labels with the same word to index dictionary or can I just label them 0,1,2,3( which is what I’m currently doing) . The problem I’m facing with this scheme is that my loss becomes NAN after an epoch. I’m not sure if the labeling is the problem it’s just a hunch. Please tell me if I am going wrong anywhere else.
