QLS seminar (Tosif Ahamed) via Zoom on 1 February 2022 at 15.00 CET

[Quantitative Life Sciences Section]

Dear All,

On Tuesday, 1 February  at 15:00 CET, Dr Tosif Ahamed 
(Lunenfeld-Tanenbaum Research Institute, Mount Sinai Hospital, Toronto, 
Canada) will give a zoom webinar titled:

*Data-driven Modeling of Animal Behavior *

Abstract:
In this talk, I will describe recent work on analyzing behavioral 
dynamics using the theory of nonlinear dynamics. I will first describe 
ways to convert time-series observations into a phase-space, which is a 
maximally predictive geometric representation of the data. The 
phase-space, once properly reconstructed, contains all dynamically 
relevant information available in the measurements. Next, I will 
describe methods to extract meaningful information from the phase space 
by analyzing its local geometry and topology. Applications include 
separating continuous behaviors into discrete motifs, identifying 
salient events, extracting long time-scale structure, quantifying 
behavioral variability and studying coupling between sub-systems.
