The result will improve with higher number of iterations. Training a Word2Vec model with phrases is very similar to training a Word2Vec model with single words. Finally, instead of directly saving the flipped strings into a feature vector, a hash value of each string is computed using Python’s built-in hash function and is saved. Association rule mining research typically focuses on positive association rules (PARs), generated from frequently occurring itemsets. The most famous topic model is undoubtedly latent Dirichlet allocation (LDA), as proposed by David Blei and his colleagues.
