Probabilistic DAG Search
Julia Grosse, Cheng Zhang, Philipp Hennig
Exciting contemporary machine learning problems have recently been phrased in the classic formalism of tree search -- most famously, the game of Go. Interestingly, the state-space…
A data-driven and model-based accelerated Hamiltonian Monte Carlo method for Bayesian elliptic inverse problems
Sijing Li, Cheng Zhang, Zhiwen Zhang +1
In this paper, we consider a Bayesian inverse problem modeled by elliptic partial differential equations (PDEs). Specifically, we propose a data-driven and model-based approach to…
Variational Bayesian Supertrees
Michael Karcher, Cheng Zhang, Frederick A Matsen
Given overlapping subsets of a set of taxa (e.g. species), and posterior distributions on phylogenetic tree topologies for each of these taxon sets, how can we infer a posterior di…
Estimating -Rank by Maximizing Information Gain
Tabish Rashid, Cheng Zhang, Kamil Ciosek
Game theory has been increasingly applied in settings where the game is not known outright, but has to be estimated by sampling. For example, meta-games that arise in multi-agent e…
Improved Variational Bayesian Phylogenetic Inference with Normalizing Flows
Cheng Zhang
Variational Bayesian phylogenetic inference (VBPI) provides a promising general variational framework for efficient estimation of phylogenetic posteriors. However, the current diag…
Non-bifurcating phylogenetic tree inference via the adaptive LASSO
Cheng Zhang, Vu Dinh, Frederick A. Matsen
Phylogenetic tree inference using deep DNA sequencing is reshaping our understanding of rapidly evolving systems, such as the within-host battle between viruses and the immune syst…
