Title: Multi-scale Human Behavior Modeling with Heterogeneous Data

Abstract:
In this era of big data, massive data are generated from heterogeneous resources every day, which provides an unprecedented opportunity for deepening our understanding of complex human behaviors. Modeling human behaviors requires robust computational methods that can not only capture semantics and useful insights from sparse and heterogeneous data, but also unravel sophisticated human behaviors at different scales. Besides, the enormous data velocity and the unparalleled scale of deep models also pose significant challenges to efficiency. In this talk, I will demonstrate a collection of research results that systematically improve the ecosystem of human behavior modeling based on representation learning. I will present practical representation learning for heterogeneous data in various settings, and show how these representation learning methods actually fill a niche to comfortably model different behaviors with atomic, compositional, and explainable operations. Finally, I will discuss how the theory of human behaviors may conversely benefit machine learning algorithms.
