Theory and example about Naive Bayes Classifier

Hi , I was wondering if there might be a miscalculation with Naive Bayes in lesson 5 nlp notebook ? I tried out what I think as the right way to do it following the steps in excel spreadsheet and I’ve noticed a slight improvement (since calculations are deterministic it might be worth noticing).

Again, I am also not a fan of paying very much attention to Naive Bayes compared to embeddings or RNNs but still it’s good to know the intuition of it. Please correct if I am thinking wrong with calculation (code) changes.

Thanks !
