Black Box Model Explanations and the Human Interpretability Expectations -- An Analysis in the Context of Homicide Prediction

1 code implementation19 Oct 2022 José Ribeiro, Níkolas Carneiro, Ronnie Alves

Intending to shed light on the explanations generated by XAI measures and their interpretabilities, this research addresses a real-world classification problem related to homicide prediction, duly endorsed by the scientific community, replicated its proposed black box model and used 6 different XAI measures to generate explanations and 6 different human experts to generate what this research referred to as Interpretability Expectations - IE.

Explanations Based on Item Response Theory (eXirt): A Model-Specific Method to Explain Tree-Ensemble Model in Trust Perspective

2 code implementations18 Oct 2022 José Ribeiro, Lucas Cardoso, Raíssa Silva, Vitor Cirilo, Níkolas Carneiro, Ronnie Alves

In recent years, XAI researchers have been formalizing proposals and developing new methods to explain black box models, with no general consensus in the community on which method to use to explain these models, with this choice being almost directly linked to the popularity of a specific method.

Prediction of Homicides in Urban Centers: A Machine Learning Approach

1 code implementation16 Aug 2020 José Ribeiro, Lair Meneses, Denis Costa, Wando Miranda, Ronnie Alves

This research presents a machine learning model to predict homicide crimes, using a dataset that uses generic data (without study location dependencies) based on incident report records for 34 different types of crimes, along with time and space data from crime reports.
