报告题目：Interpretability and credibility in Machine Learning: A Perspective of Granular Computing

内容简介：Over the recent years, we have been witnessing numerous and far-reaching developments and applications of Machine Learning (ML). Efficient and systematic design of their architectures is important. The two factors that are of paramount relevance to the successes of ML and its broad acceptance by the society involve endowing such ML models with tangible facets of their interpretability/explainability and credibility. Interpretability and explainability are the crucial capability of the model to deliver the results in a comprehended format easily understood by the user. The credibility of ML models is of concern to any application, especially the one exhibiting a high level of criticality commonly encountered in autonomous systems. With this regard, there are a number of burning questions that need to be posed and addressed: how to quantify the quality of a result produced by the ML model?  What is its credibility?  How to equip the models with some self-awareness mechanism so careful guidance for additional supportive experimental evidence could be triggered?

Proceeding with a conceptual and algorithmic pursuits, we advocate that these quests could be posed and formalized in the settings of Granular Computing. With regard to explainability, it is shown that interpretability entails results coming in the form of information granules, which support comprehension of findings. In terms of credibility, we note that any numeric result can be augmented by the associated information granules and the quality of the results is expressed in terms of the characteristics of information granules such as coverage and specificity.  Different directions are covered including confidence/ prediction intervals, granular embedding of ML models, and granular Gaussian Process models.

Several representative approaches are discussed within the realm of rule-based computing.
