A High-Performance Implementation of Bayesian Matrix Factorization with Limited Communication

no code implementations6 Apr 2020 Tom Vander Aa, Xiangju Qin, Paul Blomstedt, Roel Wuyts, Wilfried Verachtert, Samuel Kaski

We show that the combination of the two methods gives substantial improvements in the scalability of BMF on web-scale datasets, when the goal is to reduce the wall-clock time.

Scalable Bayesian Non-linear Matrix Completion

no code implementations31 Jul 2019 Xiangju Qin, Paul Blomstedt, Samuel Kaski

Matrix completion aims to predict missing elements in a partially observed data matrix which in typical applications, such as collaborative filtering, is large and extremely sparsely observed.
