Revealing and modeling the hidden state-space of dynamical systems is a fundamental problem in signal processing, control theory, and learning. Classical approaches to this problem include hidden Markov models, reinforcement learning, and various system identification algorithms. More recently, the problem has been approached by such modern machine learning techniques as kernel methods, Bayesian and Gaussian processes, latent variables, and the information bottleneck. Moreover, dynamic state-space learning is the key mechanism in the way organisms cope with complex stochastic environments, i.e., biological adaptation. One familiar example of a complex dynamic system is the authorship system in the NIPS community. Such a system can be described by both internal variables, such as links between NIPS authors, and external environment variables, such as other research communities. This complex system, which generates a vast number of papers each year, can be modeled and investigated using various parametric and non-parametric methods. In this workshop we intend to review and confront different approaches to dynamical system learning, with various applications in machine learning and neuroscience. In addition, we hope this workshop will familiarize the machine learning community with many real-world examples and applications of dynamical system learning. Such examples will also serve as the basis for the discussion of such systems in the workshop.

Naftali Tishby (The Hebrew University Jerusalem)

Naftali Tishby, is a professor of computer science and the director of the Interdisciplinary Center for Neural Computation (ICNC) at the Hebrew university of Jerusalem. He received his Ph.D. in theoretical physics from the Hebrew University and was a research staff member at MIT and Bell Labs from 1985 to 1991. He was also a visiting professor at Princeton NECI, the University of Pennsylvania and the University of California at Santa Barbara. Dr. Tishby is a leader of machine learning research and computational neuroscience. He was among the first to introduce methods from statistical physics into learning theory, and dynamical systems techniques in speech processing. His current research is at the interface between computer science, statistical physics and computational neuroscience and concerns the foundations of biological information processing and the connections between dynamics and information.
