Online Bayesian Goal Inference for Boundedly Rational Planning Agents

no code implementations NeurIPS 2020 Tan Zhi-Xuan, Jordyn Mann, Tom Silver, Josh Tenenbaum, Vikash Mansinghka

These models are specified as probabilistic programs, allowing us to represent and perform efficient Bayesian inference over an agent's goals and internal planning processes.

Deep Involutive Generative Models for Neural MCMC

no code implementations26 Jun 2020 Span Spanbauer, Cameron Freer, Vikash Mansinghka

We introduce deep involutive generative models, a new architecture for deep generative modeling, and use them to define Involutive Neural MCMC, a new approach to fast neural MCMC.

Bayesian causal inference via probabilistic program synthesis

no code implementations30 Oct 2019 Sam Witty, Alexander Lew, David Jensen, Vikash Mansinghka

This approach makes it straightforward to incorporate data from atomic interventions, as well as shift interventions, variance-scaling interventions, and other interventions that modify causal structure.

Real-time Approximate Bayesian Computation for Scene Understanding

no code implementations22 May 2019 Javier Felip, Nilesh Ahuja, David Gómez-Gutiérrez, Omesh Tickoo, Vikash Mansinghka

The underlying generative models are built from realistic simulation software, wrapped in a Bayesian error model for the gap between simulation outputs and real data.

CrossCat: A Fully Bayesian Nonparametric Method for Analyzing Heterogeneous, High Dimensional Data

1 code implementation3 Dec 2015 Vikash Mansinghka, Patrick Shafto, Eric Jonas, Cap Petschulat, Max Gasner, Joshua B. Tenenbaum

CrossCat infers multiple non-overlapping views of the data, each consisting of a subset of the variables, and uses a separate nonparametric mixture to model each view.

Automatic Inference for Inverting Software Simulators via Probabilistic Programming

no code implementations31 May 2015 Ardavan Saeedi, Vlad Firoiu, Vikash Mansinghka

Models of complex systems are often formalized as sequential software simulators: computationally intensive programs that iteratively build up probable system configurations given parameters and initial conditions.
