Certifying Fairness of Probabilistic Circuits

1 code implementation5 Dec 2022 Nikil Roashan Selvam, Guy Van Den Broeck, YooJung Choi

In this paper, we propose an algorithm to search for discrimination patterns in a general class of probabilistic models, namely probabilistic circuits.

Solving Marginal MAP Exactly by Probabilistic Circuit Transformations

no code implementations8 Nov 2021 YooJung Choi, Tal Friedman, Guy Van Den Broeck

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).

A Compositional Atlas of Tractable Circuit Operations for Probabilistic Inference

1 code implementation NeurIPS 2021 Antonio Vergari, YooJung Choi, Anji Liu, Stefano Teso, Guy Van Den Broeck

Circuit representations are becoming the lingua franca to express and reason about tractable generative and discriminative models.

On Tractable Computation of Expected Predictions

1 code implementation NeurIPS 2019 Pasha Khosravi, YooJung Choi, Yitao Liang, Antonio Vergari, Guy Van Den Broeck

In this paper, we identify a pair of generative and discriminative models that enables tractable computation of expectations, as well as moments of any order, of the latter with respect to the former in case of regression.

Learning Fair Naive Bayes Classifiers by Discovering and Eliminating Discrimination Patterns

1 code implementation10 Jun 2019 YooJung Choi, Golnoosh Farnadi, Behrouz Babaki, Guy Van Den Broeck

As machine learning is increasingly used to make real-world decisions, recent research efforts aim to define and ensure fairness in algorithmic decision making.

What to Expect of Classifiers? Reasoning about Logistic Regression with Missing Features

1 code implementation5 Mar 2019 Pasha Khosravi, Yitao Liang, YooJung Choi, Guy Van Den Broeck

While discriminative classifiers often yield strong predictive performance, missing feature values at prediction time can still be a challenge.

On Robust Trimming of Bayesian Network Classifiers

1 code implementation29 May 2018 YooJung Choi, Guy Van Den Broeck

To this end, we propose a closeness metric between Bayesian classifiers, called the expected classification agreement (ECA).
