A Markovian dynamics for C. elegans behavior across scales
Antonio C. Costa, Tosif Ahamed, David Jordan +1
How do we capture the breadth of behavior in animal movement, from rapid body twitches to aging? Using high-resolution videos of the nematode worm , we show that a sing…
Maximally predictive states: from partial observations to long timescales
Antonio Carlos Costa, Tosif Ahamed, David Jordan +1
Isolating slower dynamics from fast fluctuations has proven remarkably powerful, but how do we proceed from partial observations of dynamical systems for which we lack underlying e…
Capturing the Continuous Complexity of Behavior in C. elegans
Tosif Ahamed, Antonio Carlos Costa, Greg J. Stephens
Animal behavior is often quantified through subjective, incomplete variables that may mask essential dynamics. Here, we develop a behavioral state space in which the full instantan…
Adaptive, locally-linear models of complex dynamics
Antonio Carlos Costa, Tosif Ahamed, Greg J. Stephens
The dynamics of complex systems generally include high-dimensional, non-stationary and non-linear behavior, all of which pose fundamental challenges to quantitative understanding.…
