Title: A Neuro-Symbolic Explainer for Rare Events
Abstract
Learning from data streams is a hot topic in machine learning and data mining. This talk presents two problems and discusses streaming techniques to solve them. The first problem is the application of data stream techniques to predictive maintenance. We propose a two-layer neuro-symbolic approach to explain black-box models. The explanations are oriented toward equipment failures. For the second problem, we present a streaming algorithm for online hyperparameter tuning. The Self hyper-parameter Tuning (SPT) algorithm is an optimisation algorithm for online hyper-parameter tuning from non-stationary data streams. SPT is a wrapper over any streaming algorithm and can be used for classification, regression, and recommendation.
