Distributed Bayesian Matrix Factorization with Limited Communication

no code implementations2 Mar 2017 Xiangju Qin, Paul Blomstedt, Eemeli Leppäaho, Pekka Parviainen, Samuel Kaski

Bayesian matrix factorization (BMF) is a powerful tool for producing low-rank representations of matrices and for predicting missing values and providing confidence intervals.

Sparse group factor analysis for biclustering of multiple data sources

no code implementations29 Dec 2015 Kerstin Bunte, Eemeli Leppäaho, Inka Saarinen, Samuel Kaski

Motivation: Modelling methods that find structure in data are necessary with the current large volumes of genomic data, and there have been various efforts to find subsets of genes exhibiting consistent patterns over subsets of treatments.

Bayesian multi-tensor factorization

no code implementations15 Dec 2014 Suleiman A. Khan, Eemeli Leppäaho, Samuel Kaski

We introduce Bayesian multi-tensor factorization, a model that is the first Bayesian formulation for joint factorization of multiple matrices and tensors.
