Text Mining with TF-IDF & Cosine Similarity

A simple python repository for developing perceptron based text mining involving dataset linguistics preprocessing for text classification and extracting similar text for a given query.

New Implementation: Added PyTorch based optimization handling buggy loading of sparse 'csr_matrix' to cuda tensor.
