Factorization Machines with Theano
A Factorization Machine (FM) is a predictive model that can be used for regression and classification (Rendle 2010). FMs efficiently incorporate pairwise interactions by using factorized parameters. PyFactorizationMachines is a Theanobased Python implementation of factorization machines. Update 4/20/2017: The library is now … Continue reading
Matrix Factorization with Theano
Matrix factorization algorithms factorize a matrix D into two matrices P and Q, such that D ≈ PQ. By limiting the dimensionality of P and Q, PQ provides a lowrank approximation of D. While singular value decomposition (SVD) can also be … Continue reading
Anchor Graph Hashing in Python
I was recently collaborating on a project that relied on hashing (where I’m referring to “hashing” the same way it’s used in locality sensitive hashing, as opposed to its more conventional usage). One of my contributions was an implementation of Anchor … Continue reading
