cm-tpm 1.0.2

A Python package for data imputation using Continuous Mixtures of Tractable Probabilistic Models

cm-tpm (Continuous Mixtures of Tractable Probabilistic Models) is a Python package designed for efficient and scalable data imputation using probabilistic circuits. The package provides a flexible and user-friendly API, making it easy to integrate into data preprocessing pipelines. The package is distributed under the MIT licence.

The project was started in 2025 by Hakim Agni, under the supervision of Thomas Krak at Eindhoven University of Technology, as part of a Master's Thesis. It implements the data imputation method described in the paper Continuous Mixtures of Tractable Probabilistic Models, by Alvaro Correia, Gennaro Gala, Erik Quaeghebeur, Cassio de Campos and Robert Peharz.
