Priors on the Variance in Sparse Bayesian Learning; the demi-Bayesian Lasso [PDF]
We explore the use of proper priors for variance parameters of certain sparse Bayesian regression models. This leads to a connection between sparse Bayesian learning (SBL) models (Tipping, 2001) and the recently proposed Bayesian Lasso (Park and Casella,

Incremental Sparse Bayesian Ordinal Regression [PDF]
Ordinal Regression (OR) aims to model the ordering information between different data categories, which is a crucial topic in multi-label learning. An important class of approaches to OR models the problem as a linear combination of basis functions that ...

Iterative Reweighted Algorithms for Sparse Signal Recovery with Temporally Correlated Source Vectors [PDF]
Iterative reweighted algorithms, as a class of algorithms for sparse signal recovery, have been found to have better performance than their non-reweighted counterparts.

EM-based parameter iterative approach for sparse Bayesian channel estimation of massive MIMO system
One of the main challenges for a massive multi-input multi-output (MIMO) system is to obtain accurate channel state information despite the increasing number of antennas at the base station.

Collaborative Deep Learning for Recommender Systems [PDF]
Collaborative filtering (CF) is a successful approach commonly used by many recommender systems. Conventional CF-based methods use the ratings given to items by users as the sole source of information for learning to make recommendation.
