WG2: From Artificial Intelligence to Neuroscience, and Back
Abstract

The reinforcement learning algorithms, developed in the 80's to endow artificial agents with stronger autonomy, have had a deep influence on the study of decision-making in neuroscience after the discovery, in the 90's, of the striking similarity between these algorithms and the interactions of the cortex and basal ganglia loops with the dopaminergic system. A new exciting current in Artificial Intelligence (AI) and robotics is the development of deep learning methods. They have been steadily gaining momentum, and these have also been taught widely in the popular press as a watershed for modelling intelligence and the brain.

This workshop working group will put together views from the AI and robotics community and from neuroscience (computational and experimental) to address the following questions:

  1. Is state-of-the-art AI still in position of fruitfully inseminating neuroscience? Have deep learning methods the potential to lead to new success stories? How could these and other current methods be used to analyse data, and to formalise information processing principles in neural circuits?
  2. Conversely, are discoveries in computational neuroscience in position of feeding AI and robotics with new ideas? In these domains, is neuro-inspiration complementary to the traditional engineering approach? What might neuroscience bring to the deep learning community?

WG1: Combining macro and micro neuroimaging approaches
Abstract

Neuroimaging includes a large portfolio of techniques capable of investigating the brain at different spatial scales. Combining the various measurements in order to understand how microscopic characteristics give rise to macroscopic behaviors is a major challenge of modern neuroscience. From a medical point of view, putting together results from different neuroimaging studies in order to formulate medical diagnoses is often one of the most difficult tasks faced by physicians.

This workshop working group will identify difficulties encountered when bringing together specific neuroimaging methods such as functional MRI, microscopic MR, PET and optical imaging from the point of view of signal modeling and data analysis. The discussions will be initiated by leading experts who will present advantages, disadvantages and limitations of different brain imaging technologies.

WG3: High dimensional neural coding
Abstract

Particularly for more complex cognitive tasks, neural recordings (single and mutli unit electrodes and arrays, EEG, iEEG, fMRI, MEG) reveal complex high dimensional combinations of task and context factors that can be difficult to directly correlate with behavior. When observed at a population level however, this coding scheme is revealed to reflect a general high dimensional representation with universal properties. This same coding mechanism is seen in neural networks with fixed recurrent connections (Enel et al 2016, Fusi et al 2016, Rigotti et al 2013, Sussillo & Barak 2013).

This workshop working group will address how high dimensional representations in recurrent reservoir networks can be applied both to the interpretation and decoding of, and the modeling of high dimensional neurophysiological data.

Peter F. Dominey will make a 10 min introductory presentation briefly reviewing high dimensional coding in reservoir computing and primate cortical neurophysiology. The three co-moderators will then each make 10 min presentations where they identify open questions in the context of the goal of the workshop. In the second part of the workshop, the discussion will be focused on the points previously raised: In particular one of the goals of the working group is to identify limits of how far we can go in considering that the cortex displays reservoir dynamics, and that these dynamics provide a general purpose machine for higher cognitive function, and that this framework can form the basis for future developments in interpretation and decoding of neurophysiological signals.
