An R package for efficient estimation of generalized matrix factorization (GMF) models [1,2,3]. The package implements the adaptive stochastic gradient descent with block- and coordinate-wise sub-sampling strategies proposed in [4]. Additionally, sgdGMF implements the alternated iterative re-weighted least squares [1,3] and diagonal-Hessian quasi-Newton [1] algorithms.
