We consider learning an undirected graphical model from sparse data.

Converting ADMM to a Proximal Gradient for Efficient Sparse Estimation

1 code implementation22 Apr 2021 Ryosuke Shimmura, Joe Suzuki

In sparse estimation, such as fused lasso and convex clustering, we apply either the proximal gradient method or the alternating direction method of multipliers (ADMM) to solve the problem.

A Theoretical Analysis of the BDeu Scores in Bayesian Network Structure Learning

no code implementations15 Jul 2016 Joe Suzuki

In Bayesian network structure learning (BNSL), we need the prior probability over structures and parameters.
