[PhD] An integrated experimental and modeling approach to gaze orientation and learning
by Laurent Perrinet 20 Jun '14

20 Jun '14

An opening is available for a PhD project focusing on an integrated experimental and modeling approach to gaze orientation and learning. Please note that candidates should apply before July 15th, 2014. Cheers, Laurent Call for candidates for one PhD fellowship at the Institut de Neurosciences de la Timone CNRS & Aix-Marseille University (AMU) Gaze orientation and learning: an integrated experimental and modeling approach PhD supervisors: Anna Montagnini and Laurent Perrinet (InViBe team) How do we maintain the accuracy of our movements despite changes occurring in our environment or within the organism? Our research project is to shed a new light on this question within a unified theoretical framework centred on reinforcement learning. We will study visually driven, voluntary eye movements as a model for motor learning. Indeed, these provide an ideal experimental preparation to probe sensorimotor decisions across different time-scales, processing levels (from sensory encoding to the final categorical choice) and movement repertoire (e.g. smooth pursuit vs saccades). In addition, a remarkable flexibility of simple oculomotor behaviors has been highlighted, by manipulating the expectancy for sensory features or the outcome associated to particular motor responses. Behavioral experiments on human eye movements will be designed, implemented and used to benchmark new theoretical models based on the probabilistic framework. The main focus will be on the modulation of oculomotor behavior (latency and metric properties, such as amplitude or speed) that is observed in a changing environment, especially in relation to a dynamic reinforcement schedule. The proposed PhD is part of a project (Reinforcement and Eye Movements – REM, see http://invibe.net/LaurentPerrinet/TagAnrRem) funded by the French National Research Agency ANR, and it will be conducted in close collaborations with researchers at INT in Marseille (A. Montagnini, L. Perrinet and F. Danion) and at the University of Lille (L. Madelain and J. Jozefowiez). The Institut de Neurosciences de la Timone (see http://www.int.univ-amu.fr/?lang=en) brings together a large, young and dynamic community of scientists interested in frontline aspects of the integrative neurosciences. The net salary will be around 1430 euros per month. Applicants should have a keen interest in cognitive science and hold a Master or equivalent degree in a relevant field (computational or cognitive neuroscience, computer science, psychology, engineering, physics, or mathematics). The selection process will strongly favor candidates with excellent programming skills and/or experience with eye tracking and visual psychophysics. Knowledge of French is not mandatory, although willing to learn it will facilitate enjoying life in Marseille and its beautiful surroundings. Applications are now being accepted and until July 15th, 2014. Interested candidates should send a CV, brief summary of research accomplishments and interest, and the contact information for two to three referees familiar with the candidates’ backgrounds. Position needs to be filled by September, 1st, 2014. Please, send applications (in a single PDF file) to Anna.montagnini(a)univ-amu.fr and Laurent.perrinet(a)univ-amu.fr.

A new mechanism for linking some pieces of the cognitive brain puzzle
by Herbert Jaeger 14 Jun '14

14 Jun '14

Recipients of this mailing list may be interested to learn about a newly discovered neuro-computational mechanism. This mechanism, which I named "conceptors", suggests a common computational principle underneath phenomena as diverse as - incremental learning of dynamical patterns, - attentional focussing, - neural noise suppression, - morphing and modulating motor patterns, - learning pattern classes from a few prototype examples, - top-down bias control in hierarchical architectures, - Boolean combination of evidence in pattern classification. Conceptor-based algorithms are simple, cheap, and robust against noise and parameter variation. A number of fundamental neuro-computational problems become efficiently solved: - conceptors make it possible in the first place to govern a diversity of processing modes in a single recurrent neural network, - they enable incremental learning of temporal patterns with an option to quantify and monitor claimed neural memory capacity (coping with the catastrophic interference problem), - they lead to an auto-associative memory for dynamical patterns (a generalization of Hopfield networks to temporal patterns), - Boolean concept combinations and conceptual abstraction can be rigorously interpreted and implemented by the dynamics of recurrent neural networks (a robust solution for core parts of the neuro-symbolic integration problem).
