Leveraging Self-Consistency for Data-Efficient Amortized Bayesian Inference

no code implementations6 Oct 2023 Marvin Schmitt, Desi R. Ivanova, Daniel Habermann, Ullrich Köthe, Paul-Christian Bürkner, Stefan T. Radev

We propose a method to improve the efficiency and accuracy of amortized Bayesian inference by leveraging universal symmetries in the joint probabilistic model of parameters and data.

CO-BED: Information-Theoretic Contextual Optimization via Bayesian Experimental Design

1 code implementation27 Feb 2023 Desi R. Ivanova, Joel Jennings, Tom Rainforth, Cheng Zhang, Adam Foster

We formalize the problem of contextual optimization through the lens of Bayesian experimental design and propose CO-BED -- a general, model-agnostic framework for designing contextual experiments using information-theoretic principles.

Differentiable Multi-Target Causal Bayesian Experimental Design

1 code implementation21 Feb 2023 Yashas Annadani, Panagiotis Tigas, Desi R. Ivanova, Andrew Jesson, Yarin Gal, Adam Foster, Stefan Bauer

We introduce a gradient-based approach for the problem of Bayesian optimal experimental design to learn causal models in a batch setting -- a critical component for causal discovery from finite data where interventions can be costly or risky.

Efficient Real-world Testing of Causal Decision Making via Bayesian Experimental Design for Contextual Optimisation

no code implementations12 Jul 2022 Desi R. Ivanova, Joel Jennings, Cheng Zhang, Adam Foster

In this paper we introduce a model-agnostic framework for gathering data to evaluate and improve contextual decision making through Bayesian Experimental Design.

Implicit Deep Adaptive Design: Policy-Based Experimental Design without Likelihoods

1 code implementation NeurIPS 2021 Desi R. Ivanova, Adam Foster, Steven Kleinegesse, Michael U. Gutmann, Tom Rainforth

We introduce implicit Deep Adaptive Design (iDAD), a new method for performing adaptive experiments in real-time with implicit models.

Deep Adaptive Design: Amortizing Sequential Bayesian Experimental Design

1 code implementation3 Mar 2021 Adam Foster, Desi R. Ivanova, Ilyas Malik, Tom Rainforth

We introduce Deep Adaptive Design (DAD), a method for amortizing the cost of adaptive Bayesian experimental design that allows experiments to be run in real-time.
