One Size Does Not Fit All: Curvature-Aware Adaptive Perturbation for SAM
Alessia Rossi, Felipe Campelo, Gabriel L. Oliveira
Poor generalisation in deep neural networks is frequently associated with convergence to sharp minima. Sharpness-Aware Minimisation (SAM) improves generalisation of deep neural net…
Universal Learning of Nonlinear Dynamics
Evan Dogariu, Anand Brahmbhatt, Elad Hazan
We study the fundamental problem of one-step prediction of a marginally stable unknown nonlinear dynamical system. We describe an algorithm for this problem, based on the technique…
Efficient Spectral Control of Partially Observed Linear Dynamical Systems
Anand Brahmbhatt, Gon Buzaglo, Sofiia Druchyna +1
We propose a new method for the problem of controlling linear dynamical systems under partial observation and adversarial disturbances. Our new algorithm, Double Spectral Control (…
A New Approach to Controlling Linear Dynamical Systems
Anand Brahmbhatt, Gon Buzaglo, Sofiia Druchyna +1
We propose a new method for controlling linear dynamical systems under adversarial disturbances and cost functions. Our algorithm achieves a running time that scales polylogarithmi…
