Value Function Decomposition for Iterative Design of Reinforcement Learning Agents

no code implementations24 Jun 2022 James Macglashan, Evan Archer, Alisa Devlic, Takuma Seno, Craig Sherstan, Peter R. Wurman, Peter Stone

These value estimates provide insight into an agent's learning and decision-making process and enable new training methods to mitigate common problems.

Linear dynamical neural population models through nonlinear embeddings

no code implementations NeurIPS 2016 Yuanjun Gao, Evan Archer, Liam Paninski, John P. Cunningham

A body of recent work in modeling neural activity focuses on recovering low-dimensional latent features that capture the statistical structure of large-scale neural populations.

Black box variational inference for state space models

no code implementations23 Nov 2015 Evan Archer, Il Memming Park, Lars Buesing, John Cunningham, Liam Paninski

These models have the advantage of learning latent structure both from noisy observations and from the temporal ordering in the data, where it is assumed that meaningful correlation structure exists across time.

Bayesian Entropy Estimation for Countable Discrete Distributions

2 code implementations2 Feb 2013 Evan Archer, Il Memming Park, Jonathan Pillow

The Pitman-Yor process, a generalization of Dirichlet process, provides a tractable prior distribution over the space of countably infinite discrete distributions, and has found major applications in Bayesian non-parametric statistics and machine learning.

Bayesian estimation of discrete entropy with mixtures of stick-breaking priors

no code implementations NeurIPS 2012 Evan Archer, Il Memming Park, Jonathan W. Pillow

We consider the problem of estimating Shannon's entropy H in the under-sampled regime, where the number of possible symbols may be unknown or countably infinite.
