Workshop
Hierarchical Organization of Behavior: Computational, Psychological and Neural Perspectives (Part 2)

Sat Dec 08 09:00 AM -- 06:00 PM (PST) @ Westin: Callaghan

The aim of this workshop is to discuss current ideas from computer science, psychology and neuroscience regarding learning and control of hierarchically structured behavior. Psychological research has long emphasized that human behavior is hierarchically structured. Indeed, a hierarchical organization of human behavior that matches the hierarchical structure of real-world problems has been the focus of much empirical and theoretical research, and has played a pivotal role in research on organized, goal-directed behavior. Behavioral hierarchy has been of longstanding interest within neuroscience as well, where it has been considered to relate closely to prefrontal cortical function. The prefrontal cortex, which, with its high cognitive functions, remains the most poorly understood area of the brain, has been repeatedly implicated in supporting and executing hierarchical learning and control. In yet a third field, recent developments within machine learning have led to the emergence of 'hierarchical reinforcement learning'. This line of research has begun investigating in depth how optimal control can learn, and make use of, hierarchical structures, specifically, how hierarchies of skills (also termed options, macros or temporally abstract actions) could by learned and utilized optimally. The workshop will bring together front-line researchers from each of these fields, with the aim of gleaning new insights from the integration of knowledge from these somewhat disparate areas of active research.

Yael Niv received her MA in psychobiology from Tel Aviv University and her PhD from the Hebrew University in Jerusalem, having conducted a major part of her thesis research at the Gatsby Computational Neuroscience Unit in UCL. After a short postdoc at Princeton she became faculty at the Psychology Department and the Princeton Neuroscience Institute. Her lab's research focuses on the neural and computational processes underlying reinforcement learning and decision-making in humans and animals, with a particular focus on representation learning. She recently co-founded the Rutgers-Princeton Center for Computational Cognitive Neuropsychiatry, and is currently taking the research in her lab in the direction of computational psychiatry.
