Graph Convolutional Matrix Completion

riannevdberg/gc-mc 7 Jun 2017

We consider matrix completion for recommender systems from the point of view of link prediction on graphs.

Matrix Completion and Low-Rank SVD via Fast Alternating Least Squares

iskandr/fancyimpute 9 Oct 2014

The matrix-completion problem has attracted a lot of attention, largely as a result of the celebrated Netflix competition.

Hybrid Recommender System based on Autoencoders

fstrub95/Autoencoders_cf 24 Jun 2016

A standard model for Recommender Systems is the Matrix Completion setting: given partially known matrix of ratings given by users (rows) to items (columns), infer the unknown ratings.

Sequence-Aware Recommender Systems

taylorhawks/RNN-music-recommender 23 Feb 2018

In this work we review existing works that consider information from such sequentially-ordered user- item interaction logs in the recommendation process.

Unsupervised Metric Learning in Presence of Missing Data

rsonthal/MRMissing.jl 19 Jul 2018

Here, we present a new algorithm MR-MISSING that extends these previous algorithms and can be used to compute low dimensional representation on data sets with missing entries.

Inductive Matrix Completion Based on Graph Neural Networks

muhanzhang/IGMC ICLR 2020

Under the extreme setting where not any side information is available other than the matrix to complete, can we still learn an inductive matrix completion model?

Matrix Completion on Graphs

kushagramahajan/GraphRegMC-scRNAseq 7 Aug 2014

Our main goal is thus to find a low-rank solution that is structured by the proximities of rows and columns encoded by graphs.

Collaborative Filtering with Graph Information: Consistency and Scalable Methods

rofuyu/exp-grmf-nips15 NeurIPS 2015

Low rank matrix completion plays a fundamental role in collaborative filtering applications, the key idea being that the variables lie in a smaller subspace than the ambient space.

Low-Rank Inducing Norms with Optimality Interpretations

LowRankOpt/LRINorm 9 Dec 2016

A posteriori guarantees on solving an underlying rank constrained optimization problem with these convex relaxations are provided.

Geometric Matrix Completion with Recurrent Multi-Graph Neural Networks

fmonti/mgcnn NeurIPS 2017

Matrix completion models are among the most common formulations of recommender systems.
