Representation, Coding and Computation in Neural Circuits


source: Simons Institute      2018年2月12日
The aim of this workshop is to shed light, at the level of cortical circuits, on issues of representation and coding such as sparsity and high-dimensionality, spikes and coding capacity in the presence of noise. It will also address questions related to how neurons compute: the role of dendritic nonlinearities and clustered plasticity, recurrent circuits, excitatory-inhibitory balance and models of cooperative computation (as opposed to single neuron computation).

Applications in the Natural Sciences and Physical Systems


source: Simons Institute          2018年2月26日
We are entering an era of real-time discovery and inference from instruments such as astronomical telescopes, light sources, high-energy physics particle trackers, brain-machine interfaces, earthquake detectors and environmental sensors. Increasingly, however, such inferences from large volumes of complex data must be acted on with very little or no human cognition in the loop due to the real-time requirements of the experiment or feedback from the observations. This workshop will explore the computational requirements of such applications, with particular emphasis on new techniques for handling these challenges including workflow design, machine learning and novel computational architectures.
