Variational Combinatorial Sequential Monte Carlo Methods for Bayesian Phylogenetic Inference

1 code implementation31 May 2021 Antonio Khalil Moretti, Liyi Zhang, Christian A. Naesseth, Hadiah Venner, David Blei, Itsik Pe'er

Bayesian phylogenetic inference is often conducted via local or sequential search over topologies and branch lengths using algorithms such as random-walk Markov chain Monte Carlo (MCMC) or Combinatorial Sequential Monte Carlo (CSMC).

Accurate Protein Structure Prediction by Embeddings and Deep Learning Representations

Particle Smoothing Variational Objectives

1 code implementation20 Sep 2019 Antonio Khalil Moretti, Zizhao Wang, Luhuan Wu, Iddo Drori, Itsik Pe'er

We apply SVO to three nonlinear latent dynamics tasks and provide statistics to rigorously quantify the predictions of filtered and smoothed objectives.

Smoothing Nonlinear Variational Objectives with Sequential Monte Carlo

no code implementations ICLR Workshop DeepGenStruct 2019 Antonio Moretti, Zizhao Wang, Luhuan Wu, Itsik Pe'er

The task of recovering nonlinear dynamics and latent structure from a population recording is a challenging problem in statistical neuroscience motivating the development of novel techniques in time series analysis.

Parkinson's Disease Digital Biomarker Discovery with Optimized Transitions and Inferred Markov Emissions

1 code implementation11 Nov 2017 Avinash Bukkittu, Baihan Lin, Trung Vu, Itsik Pe'er

These observations were modeled as a cycle of hidden states with randomness allowing deviation from a canonical pattern of transitions and emissions, under the hypothesis that the averaged features of hidden states would serve to informatively characterize classes of patients/controls.
