| Summary : Collective Matrix Factorization for Recommender Systems
|
Description :
Collective matrix factorization (a.k.a. multi-view or multi-way
factorization, Singh, Gordon, (2008) < doi:10.1145/1401890.1401969>)
tries to approximate a (potentially very sparse or having many missing
values) matrix \'X\' as the product of two low-dimensional matrices,
optionally aided with secondary information matrices about rows and/or
columns of \'X\', which are also factorized using the same latent
components. The intended usage is for recommender systems,
dimensionality reduction, and missing value imputation. Implements
extensions of the original model (Cortes, (2018) < arXiv:1809.00366>)
and can produce different factorizations such as the weighted
\'implicit-feedback\' model (Hu, Koren, Volinsky, (2008)
< doi:10.1109/ICDM.2008.22>), the \'weighted-lambda-regularization\'
model, (Zhou, Wilkinson, Schreiber, Pan, (2008)
< doi:10.1007/978-3-540-68880-8_32>), or the enhanced model with
\'implicit features\' (Rendle, Zhang, Koren, (2019) < arXiv:1905.01395>),
with or without side information. Can use gradient-based procedures or
alternating-least squares procedures (Koren, Bell, Volinsky, (2009)
< doi:10.1109/MC.2009.263>), with either a Cholesky solver, a faster
conjugate gradient solver (Takacs, Pilaszy, Tikk, (2011)
< doi:10.1145/2043932.2043987>), or a non-negative coordinate descent
solver (Franc, Hlavac, Navara, (2005) < doi:10.1007/11556121_50>),
providing efficient methods for sparse and dense data, and mixtures
thereof. Supports L1 and L2 regularization in the main models, offers
alternative most-popular and content-based models, and implements
functionality for cold-start recommendations and imputation of 2D data.
