Matrix Completion is a method for recovering lost information. It originates from machine learning and usually deals with highly sparse matrices. Missing or unknown data is estimated using the low-rank matrix of the known data.

CayleyNets: Graph Convolutional Neural Networks with Complex Rational Spectral Filters

amoliu/CayleyNet 22 May 2017

The rise of graph-structured data such as social networks, regulatory networks, citation graphs, and functional brain networks, in combination with resounding success of deep learning in various applications, has brought the interest in generalizing deep learning models to non-Euclidean domains.

Estimating Missing Data in Temporal Data Streams Using Multi-directional Recurrent Neural Networks

WenjieDu/PyPOTS 23 Nov 2017

Existing methods address this estimation problem by interpolating within data streams or imputing across data streams (both of which ignore important information) or ignoring the temporal aspect of the data and imposing strong assumptions about the nature of the data-generating process and/or the pattern of missing data (both of which are especially problematic for medical data).

Compressed sensing of low-rank plus sparse matrices

svary/lrps-recovery 18 Jul 2020

This manuscript develops similar guarantees showing that $m\times n$ matrices that can be expressed as the sum of a rank-$r$ matrix and a $s$-sparse matrix can be recovered by computationally tractable methods from $\mathcal{O}(r(m+n-r)+s)\log(mn/s)$ linear measurements.

A regularized deep matrix factorized model of matrix completion for image restoration

lizhemin15/zmtools 29 Jul 2020

In this work, we propose a Regularized Deep Matrix Factorized (RDMF) model for image restoration, which utilizes the implicit bias of the low rank of deep neural networks and the explicit bias of total variation.

Inductive Matrix Completion Using Graph Autoencoder

swtheing/imc-gae 25 Aug 2021

However, without node content (i. e., side information) for training, the user (or item) specific representation can not be learned in the inductive setting, that is, a model trained on one group of users (or items) cannot adapt to new users (or items).
