Faster Least Squares Optimization
Jonathan Lacotte, Mert Pilanci
We investigate iterative methods with randomized preconditioners for solving overdetermined least-squares problems, where the preconditioners are based on a random embedding of the…
Risk-sensitive safety specifications for stochastic systems using Conditional Value-at-Risk
Margaret P. Chapman, Jonathan P. Lacotte, Kevin M. Smith +4
This paper proposes a safety analysis method that facilitates a tunable balance between the worst-case and risk-neutral perspectives. First, we define a risk-sensitive safe set to…
High-Dimensional Optimization in Adaptive Random Subspaces
Jonathan Lacotte, Mert Pilanci, Marco Pavone
We propose a new randomized optimization method for high-dimensional problems which can be seen as a generalization of coordinate descent to random subspaces. We show that an adapt…
A Risk-Sensitive Finite-Time Reachability Approach for Safety of Stochastic Dynamic Systems
Margaret P. Chapman, Jonathan Lacotte, Aviv Tamar +7
A classic reachability problem for safety of dynamic systems is to compute the set of initial states from which the state trajectory is guaranteed to stay inside a given constraint…
