Prof. Shuvra S. Bhattacharyya, University of Maryland, USA: "Design and Implementation of Adaptive Stream Mining Systems using Lightweight Dataflow Graphics"

Host: Prof. Johan Lilius, Åbo Akademi University

Abstract: With the increasing need for accurate mining and classification from multimedia data content, and the growth of such multimedia applications in mobile and distributed architectures, stream mining systems require increasing amounts of flexibility, extensibility, and adaptivity for effective deployment. In this talk, I will present a novel approach to address this challenge. This approach rigorously integrates foundations of dataflow modeling for high-–level signal processing system design, and adaptive stream mining based on dynamic topologies of classifiers. In particular, I will introduce a new design environment, called the lightweight dataflow for dynamic data driven adaptive systems (LiD4E) environment. LiD4E provides formal semantics, rooted in dataflow principles, for design and implementation of a broad class of multimedia stream mining topologies. I will demonstrate the utility of these new design methods on an energy–constrained, multi–mode stream mining system for face detection.
