ABCpy, a machine learning library developed by teams at the University of Oxford, Warwick University, Harvard University, and others has used γ-ABC, a python package proposed by our researchers* in the Imperfect Information Learning Team in RIKEN AIP and others as a part of their research paper titled “γ-ABC: Outlier-Robust Approximate Bayesian Computation based on A Robust Divergence Estimator” **accepted at AISTATS-21 this year.

In this paper, Fujisawa et al.(2021) propose a robust Approximate Bayesian Computation (ABC) that can achieve high accuracy even under contaminated data with a lot of noise or outliers. ABC is an inference scheme for models to simulate complex phenomena and is used in a wide range of scientific research fields, e.g., cosmology, genetics, and biology.

The integration of this method will allow many researchers and data analysts around the world working in a variety of scientific fields to use this method without implementation and to perform highly reliable simulations quickly.
