Our PhD student Mara Graziani discussed the topic of defining machine learning interpretability at CIBM<\/a> (Center for Biomedical Imaging, Switzerland). She also presented our latest applications to the histopathology domain. In particular, she covered our recent work on the “Evaluation and Comparison of CNN Visual Explanations for Histopathology”. She then explained how interpretability can be used in a proactive way to improve model performance.

Title: <\/strong>A myth-busting attempt for DL interpretability: discussing taxonomies, methodologies and applications to medical imaging.<\/p>\n\n\n\n

Abstract: <\/strong><\/p>\n\n\n\n

Deep Learning (DL) models report almost perfect accuracy on some medical tasks, though this seems to plunge in real-world practices [1]. Started in 2009 as the generation of deep visualizations [2, 3], the field of interpretability has grown and developed over the years, with the intent of understanding why such failures happen and discovering hidden and erroneous behaviors. Several interpretability techniques were then developed to address the fundamentally incomplete problem of evaluating DL models on the sole task performance [4]. <\/p>\n\n\n\n

While defining the key terms used in the field, I will try to bust some myths on DL interpretability: are explainable and interpretable the same thing? Is a \u201ctransparent\u201d model an \u201cinterpretable\u201d model? Besides, within the application in the field of medical imaging, I will describe the risk of confirmation bias and present our work on evaluating the reliability of interpretability methods. Finally, I will bring examples from our previous works on how interpretable AI can be used to improve model performance and reduce the distance between the clinical and the DL ontologies. <\/p>\n\n\n\n
