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).
