Machine Learning
SINDy
Can we adapt sparse regression techniques to infer the underlying hypergraphs from time-series data in a model-free fashion? How important are higher-order interactions in the brain?

Reservior computing
Reservoir Computing (RC) is a simple and efficient model-free framework for forecasting the behavior of nonlinear dynamical systems from data. I am interested in understanding the success as well as identifying limitations of RC.

Reinforcement learning
Can we use reinforcement learning (RL) to improve synchronization? Would the solutions found by RL be interpretable?
