Normalizing Flows for Knockoff-free Controlled Feature Selection

1 code implementation3 Jun 2021 Derek Hansen, Brian Manzo, Jeffrey Regier

To circumvent the need to enforce the swap property, FlowSelect uses a novel MCMC-based procedure to directly compute p-values for each feature.

Flows Succeed Where GANs Fail: Lessons from Low-Dimensional Data

1 code implementation17 Jun 2020 Tianci Liu, Jeffrey Regier

Normalizing flows and generative adversarial networks (GANs) are both approaches to density estimation that use deep neural networks to transform samples from an uninformative prior distribution to an approximation of the data distribution.

Decision-Making with Auto-Encoding Variational Bayes

2 code implementations NeurIPS 2020 Romain Lopez, Pierre Boyeau, Nir Yosef, Michael. I. Jordan, Jeffrey Regier

To make decisions based on a model fit with auto-encoding variational Bayes (AEVB), practitioners often let the variational distribution serve as a surrogate for the posterior distribution.

A joint model of unpaired data from scRNA-seq and spatial transcriptomics for imputing missing gene expression measurements

3 code implementations6 May 2019 Romain Lopez, Achille Nazaret, Maxime Langevin, Jules Samaran, Jeffrey Regier, Michael. I. Jordan, Nir Yosef

Building upon domain adaptation work, we propose gimVI, a deep generative model for the integration of spatial transcriptomic data and scRNA-seq data that can be used to impute missing genes.

Rao-Blackwellized Stochastic Gradients for Discrete Distributions

1 code implementation10 Oct 2018 Runjing Liu, Jeffrey Regier, Nilesh Tripuraneni, Michael. I. Jordan, Jon McAuliffe

We wish to compute the gradient of an expectation over a finite or countably infinite sample space having $K \leq \infty$ categories.

Information Constraints on Auto-Encoding Variational Bayes

no code implementations NeurIPS 2018 Romain Lopez, Jeffrey Regier, Michael. I. Jordan, Nir Yosef

We show how to apply this method to a range of problems, including the problems of learning invariant representations and the learning of interpretable representations.

Approximate Inference for Constructing Astronomical Catalogs from Images

1 code implementation28 Feb 2018 Jeffrey Regier, Andrew C. Miller, David Schlegel, Ryan P. Adams, Jon D. McAuliffe, Prabhat

We present a new, fully generative model for constructing astronomical catalogs from optical telescope image sets.

Cataloging the Visible Universe through Bayesian Inference at Petascale

1 code implementation31 Jan 2018 Jeffrey Regier, Kiran Pamnany, Keno Fischer, Andreas Noack, Maximilian Lam, Jarrett Revels, Steve Howard, Ryan Giordano, David Schlegel, Jon McAuliffe, Rollin Thomas, Prabhat

We construct an astronomical catalog from 55 TB of imaging data using Celeste, a Bayesian variational inference code written entirely in the high-productivity programming language Julia.

Stochastic Cubic Regularization for Fast Nonconvex Optimization

no code implementations NeurIPS 2018 Nilesh Tripuraneni, Mitchell Stern, Chi Jin, Jeffrey Regier, Michael. I. Jordan

This paper proposes a stochastic variant of a classic algorithm---the cubic-regularized Newton method [Nesterov and Polyak 2006].

A deep generative model for gene expression profiles from single-cell RNA sequencing

2 code implementations7 Sep 2017 Romain Lopez, Jeffrey Regier, Michael Cole, Michael Jordan, Nir Yosef

We also extend our framework to account for batch effects and other confounding factors, and propose a Bayesian hypothesis test for differential expression that outperforms DESeq2.

Fast Black-box Variational Inference through Stochastic Trust-Region Optimization

no code implementations NeurIPS 2017 Jeffrey Regier, Michael. I. Jordan, Jon McAuliffe

We introduce TrustVI, a fast second-order algorithm for black-box variational inference based on trust-region optimization and the reparameterization trick.
