A library for factorization machines and polynomial networks for classification and regression in Python.
Factorization machines and polynomial networks are machine learning models that can capture feature interaction (co-occurrence) through polynomial terms. Because feature interactions can be very sparse, it’s common to use low rank, factorized representations; this way, we can learn weights even for feature co-occurrences that haven’t been observed at training time.
Factorization machines are popular for recommender systems, as they are a generalization of matrix completion models.
