MDF-Net for abnormality detection by fusing X-rays with clinical data

1 code implementation26 Feb 2023 Chihcheng Hsieh, Isabel Blanco Nobre, Sandra Costa Sousa, Chun Ouyang, Margot Brereton, Jacinto C. Nascimento, Joaquim Jorge, Catarina Moreira

In this work, we propose a novel architecture consisting of two fusion methods that enable the model to simultaneously process patients' clinical data (structured data) and chest X-rays (image data).

Benchmarking Counterfactual Algorithms for XAI: From White Box to Black Box

1 code implementation4 Mar 2022 Catarina Moreira, Yu-Liang Chou, Chihcheng Hsieh, Chun Ouyang, Joaquim Jorge, João Madeiras Pereira

This study investigates the impact of machine learning models on the generation of counterfactual explanations by conducting a benchmark evaluation over three different types of models: decision-tree (fully transparent, interpretable, white-box model), a random forest (a semi-interpretable, grey-box model), and a neural network (a fully opaque, black-box model).

DiCE4EL: Interpreting Process Predictions using a Milestone-Aware Counterfactual Approach

no code implementations19 Jul 2021 Chihcheng Hsieh, Catarina Moreira, Chun Ouyang

We design an extension of DiCE, namely DiCE4EL (DiCE for Event Logs), that can generate counterfactual explanations for process prediction, and propose an approach that supports deriving milestone-aware counterfactual explanations at key intermediate stages along process execution to promote interpretability.
