NCS

by Giacomo Indiveri — last modified Nov 03, 2011 01:12 PM
Welcome to the Neuromorphic Cognitive Systems group, at the Institute of Neuroinformatics, University of Zurich and ETH Zurich.
The NCS group was established in early 2009 at the Institute of Neuroinformatics to study and develop computational models, hybrid analog/digital VLSI circuits, and multi-chip event-based systems for implementing Neuromorphic Cognitive Systems.
Currently, our group consists of a Senior Lecturer, one senior post-doctoral researcher, seven PhD students. In addition Master students have joined and can join the group to work on thesis projects.

Neuromorphic Cognitive Systems

neuromorphic-technologyWhat is a neuromorphic cognitive system and what is neuromorphic cognition?

We don't have a comprehensive answer to these questions yet. But our work is aimed at bridging the gap from simple reactive neuromorphic sensory-motor systems to ones that are cognitive in quality: e.g. neuromorphic architectures that can reason about the actions to take, in response to the combinations of external stimuli, internal states, and behavioral objectives.

We focus on analog/digital VLSI architectures that use the physics of silicon to reproduce the biophysics of biological neural systems, and  multi-chip systems that communicate using asynchronous event-based signals (spikes).

Our main contributions to neuromorphic VLSI technology consist of novel low-power silicon neuron circuits, dynamic silicon synapses, hybrid analog/digital spike-based learning mechanisms, soft Winner-take-all networks, and asynchronous digital communication circuits and systems.
