DESCRIPTION:Please join us for our fortnightly Computational Neuroscience 
 journal club on Tuesday 14th November at 2pm UK time in the CBL seminar ro
 om\, or online on zoom.\n\nThe title is ‘Low rank RNNs’\, presented by
  Youjing Yu and Yashar Ahmadian.\n\nZoom information: https://eng-cam.zoom

 rained to perform a range of tasks\, they incorporate temporal information
  and\, most important of all\, they can model the brain’s processes quit
 e well. However\, it is very difficult to understand how the connectivity 
 in RNNs give rise to the input-output mappings that they are able to perfo
 rm. In this talk\, we look at Ostojic Lab's work on a special family of RN
 Ns - low-rank RNNs. In the first part I will give an introduction to the t
 heoretical framework of RNN\, before explaining how the (sub)population st
 atistics give rise to dynamics [1\, 2]. In the second part Yashar will tak
 e over to explain how we can reverse-engineer the trained full RNN network
 s to produce the low-rank versions that matches the performance of the ful
 l-rank RNNs. Finally\, Yashar will talk about how RNNs are able to perform
  context-dependent flexible tasks [3].\n\n[1] Mastrogiuseppe\, Francesca\,
