One-hot encoding Previously, we introduced a quick note for one-hot encoding. It is a representation of categorical variables as binary vectors. It is a group of bits among which the legal combinations of values are only those with a single high (1) […]

This post introduces a python script to process the movie lens datasets, generate a negative sample, and transforms the datasets into SVM light format. The format is also known as libfm format used in many factorization machines. Movie Lens datasets MovieLens is a web-based recommender system and virtual […]
