“Historically, the run time of implicit mechanics has been dominated by the time required to solve a large sparse linear system. The default solver is a multifrontal sparse matrix factorization, which will reliably solve ill conditioned, indefinite problems. The multifrontal method turns a sparse matrix factorization into a directed acyclic graph of smaller, dense “frontal”…

“Machine learning (ML), particularly deep learning, is being used everywhere. However, not always is used well, ethically and scientifically. In this talk we first do a deep dive in the limitations of supervised ML and data, its key component. We cover small data, datification, bias, predictive optimization issues, evaluating success instead of harm, and pseudoscience,…

“The acquisition of features for patient diagnostics, treatment planing and monitoring purposes is costly. Moreover, when patients with chronic diseases are called to used mobile health apps, they are also called to interact with the app in a regular way; the willingness to do so may wane with time. In this talk, we see forms…

“The talk will discuss Concept Relevance Propagation (CRP) and Prototypical Concept Explanation (PCX), two next-generation Explainable AI (XAI) methods, which explain individual predictions of an AI model in terms of human understandable concepts and allow to systematically investigate global model behaviors. Furthermore, the talk will present the potential of these novel methods to provide deep…
