Solving Marginal MAP Exactly by Probabilistic Circuit Transformations

AISTATS 2022poster

Probabilistic circuits (PCs) are a class of tractable probabilistic models that allow efficient, often linear-time, inference of queries such as marginals and most probable explanations (MPE). However, marginal MAP, which is central to many decision-making problems, remains a hard query for PCs unle…

A Compositional Atlas of Tractable Circuit Operations for Probabilistic Inference

NeurIPS 2021oral

Circuit representations are becoming the lingua franca to express and reason about tractable generative and discriminative models. In this paper, we show how complex inference scenarios for these models that commonly arise in machine learning---from computing the expectations of decision tree ensem…

Group Fairness by Probabilistic Modeling with Latent Fair Decisions

AAAI 2021technical

Machine learning systems are increasingly being used to make impactful decisions such as loan applications and criminal justice risk assessments, and as such, ensuring fairness of these systems is critical. This is often challenging as the labels in the data are biased. This paper studies learning f…

On Tractable Computation of Expected Predictions

NeurIPS 2019poster

Computing expected predictions of discriminative models is a fundamental task in machine learning that appears in many interesting applications such as fairness, handling missing values, and data analysis. Unfortunately, computing expectations of a discriminative model with respect to a probability…
