[introductory] Learning from Data Streams: Challenges, Issues, and Opportunities

Summary

In this tutorial we will discuss the problem of learning from data streams generated by evolving nonstationary processes. It will overview the advances of techniques, methods, and tools that are dedicated to manage, exploit and interpret data streams generated from time-evolving environments. In particular, the tutorial will examine the problems of learning classification and regression models from high-speed streams of non-stationary data. How to design the experimental setup and evaluate those models. We will also discuss issues related to concept drift, change detection, and novelty detection. Auto-ML for data streams.
