Naive Bayes Classifier - Revisited

During the last week, I’ve been following up work with a side project to do machine learning with Urbanesia’s comprehensive data. A lot of late night reading and fiddling with foreign codes were the highlights of my last week. Wanted to elaborate my implementations and how several kinds of technologies affect benchmarks particularly with classification performance. The repo for the codes is at Github here. During time span of the first batch of codes until now, I have made lots of changes to the codes and also the data store. [Read More]
