Kai Puolamäki: Explainable and robust AI for the VILMA virtual laboratory

Abstract: I will provide an overview of our new Virtual Laboratory for Molecular Level Atmospheric Transformations (VILMA) Centre of Excellence and discuss why explainable AI (XAI) and quantifying uncertainties is essential for us. As an example of our ongoing work, I will describe SLISEMAP, a supervised manifold visualisation method, a technique for XAI developed by us that finds local explanations for all data items. SLISEMAP produces (typically) two-dimensional global visualisation of the black box model such that data items with similar local explanations will be embedded nearby.
