Probabilistic Circuits with Constraints via Convex Optimization

no code implementations19 Mar 2024 Soroush Ghandi, Benjamin Quost, Cassio de Campos

This work addresses integrating probabilistic propositional logic constraints into the distribution encoded by a probabilistic circuit (PC).

Probabilistic Integral Circuits

no code implementations25 Oct 2023 Gennaro Gala, Cassio de Campos, Robert Peharz, Antonio Vergari, Erik Quaeghebeur

In contrast, probabilistic circuits (PCs) are hierarchical discrete mixtures represented as computational graphs composed of input, sum and product units.

Probabilistic Multi-Dimensional Classification

1 code implementation10 Jun 2023 Vu-Linh Nguyen, Yang Yang, Cassio de Campos

We propose a formal framework for probabilistic MDC in which learning an optimal multi-dimensional classifier can be decomposed, without loss of generality, into learning a set of (smaller) single-variable multi-class probabilistic classifiers and a directed acyclic graph.

Continuous Mixtures of Tractable Probabilistic Models

1 code implementation21 Sep 2022 Alvaro H. C. Correia, Gennaro Gala, Erik Quaeghebeur, Cassio de Campos, Robert Peharz

Meanwhile, tractable probabilistic models such as probabilistic circuits (PCs) can be understood as hierarchical discrete mixture models, and thus are capable of performing exact inference efficiently but often show subpar performance in comparison to continuous latent-space models.

Bayesian Kernelised Test of (In)dependence with Mixed-type Variables

no code implementations9 May 2021 Alessio Benavoli, Cassio de Campos

A fundamental task in AI is to assess (in)dependence between mixed-type variables (text, image, sound).

Towards Robust Classification with Deep Generative Forests

1 code implementation11 Jul 2020 Alvaro H. C. Correia, Robert Peharz, Cassio de Campos

Decision Trees and Random Forests are among the most widely used machine learning models, and often achieve state-of-the-art performance in tabular, domain-agnostic datasets.

Joints in Random Forests

1 code implementation NeurIPS 2020 Alvaro H. C. Correia, Robert Peharz, Cassio de Campos

Decision Trees (DTs) and Random Forests (RFs) are powerful discriminative learners and tools of central importance to the everyday machine learning practitioner and data scientist.

On Pruning for Score-Based Bayesian Network Structure Learning

1 code implementation23 May 2019 Alvaro H. C. Correia, James Cussens, Cassio de Campos

Many algorithms for score-based Bayesian network structure learning (BNSL), in particular exact ones, take as input a collection of potentially optimal parent sets for each variable in the data.
