Current Trends in Learning from Data StreamsSpeaker: João Gama – Porto, Portugal

AbstractLearning from data streams is a hot topic in machine learning and data mining. In this talk, we present three different problems and discuss streaming techniques to solve them. The first problem is the application of data stream techniques to telecommunications fraud detection. We propose an algorithm for the interconnected by-pass fraud problem. This real-world problem requires processing high-speed telecommunications data and providing fraud alarms in real-time. For the second problem, we present an architecture to explain black-box models for predictive maintenance. The explanations are oriented toward equipment anomalies. For the third problem, we present one of the first algorithms for online hyper-parameter tuning for streaming data. The Self hyper-Parameter Tunning (SPT) algorithm is an optimization algorithm for online hyper-parameter tuning from non-stationary data streams. SPT works as a wrapper over any streaming algorithm and can be used for classification, regression, and recommendation.
