2015-16: CCNS: Mathematics of Neural Networks and Neural Codes: March 9-11, 2016
Workshop Information
Participation is by invitation only.
This workshop will be held at SAMSI in Research Triangle Park, NC.
Description:
This workshop will feature a full day of talks, targeting specific areas in the theory of neural networks and neural codes that are currently active areas of research. The second and third days will be focused on research sessions to further collaboration among the participants.
On the networks side, the focus is on training and fitting various types of networks (discrete models, rate models, spiking models) to produce dynamic activity patterns. This necessitates both a deep understanding of the dynamics of the networks in question, as well as state-of-the-art fitting techniques. Recent theoretical advances have led to an improved understanding of the dynamics of threshold-linear network, spiking networks with embedded cell assemblies, and pattern storage in Hopfield networks. Data sets for training these networks consist of synthetic spiking data, generated by spiking networks where we can control the "ground truth," and real spiking data from electrophysiological recordings.
On the neural coding side, the emphasis is on the further development of topological and algebraic methods for analyzing neural activity from simultaneous recordings of neurons. This activity can be pre-processed to obtain neural correlations and neural codes. Many mathematical questions arise when trying to understand how important features of correlation or coding structure can be extracted from these data. The workshop will explain recent advances to participants, and build on existing research collaborations.
