Special Guest Lecturer

Nonlinear Filtering and Sequential Analysis for Hidden Markov ModelsProf. B.L. Rozovsky
Professor of Mathematics and Aerospace and Mechanical Engineering Center for Applied Mathematical SciencesUSC I will discuss some new statistical algorithms that proved to be efficient in a range of emerging applications. These include: computer vision, target tracking in a video-stream, intrusion detection in high speed computer networks, etc.
The first part of the talk is concerned with recent progress in theory and applications of nonlinear filtering. I will argue that banks of interacting (nonlinear) Bayesian matched filters can be successfully utilized to handle dim and acutely maneuvering targets.
The potential range of applications of the developed spatial-temporal tracking algorithms includes a new generation of tracking systems for missile defense, terrestrial reconnaissance, machine vision systems, and certain medical imaging applications.
In the second part of the talk I will discuss an efficient anomaly detection system that detects denial-of-service attacks at multi-gigabit speeds with minimal detection delay for a given low false alarm rate. The proposed constant false alarm rate detector utilizes ideas of sequential statistical analysis. The algorithm is computationally simple and self-learning, it adapts well to various network loads and usage patterns. Biography:Dr. Boris Rozovsky is Professor of Mathematics and Aerospace and Mechanical Engineering at the University of Southern California.
