SAVER: A Toolbox for Sampling-Based, Probabilistic Verification of Neural Networks

Vignesh Sivaramakrishnan, Krishna C. Kalagarla, Rosalyn Devonport +3

We present a neural network verification toolbox to 1) assess the probability of satisfaction of a constraint, and 2) synthesize a set expansion factor to achieve the probability o…

Go With the Flow: Fast Diffusion for Gaussian Mixture Models

George Rapakoulias, Ali Reza Pedram, Fengjiao Liu +2

Schrodinger Bridges (SBs) are diffusion processes that steer, in finite time, a given initial distribution to another final one while minimizing a suitable cost functional. Althoug…

Recursively Feasible Stochastic Model Predictive Control for Time-Varying Linear Systems Subject to Unbounded Disturbances

Jacob W. Knaup, Panagiotis Tsiotras

Model predictive control solves a constrained optimization problem online in order to compute an implicit closed-loop control policy. Recursive feasibility -- guaranteeing that the…

DUST: A Framework for Data-Driven Density Steering

Joshua Pilipovsky, Panagiotis Tsiotras

We consider the problem of data-driven stochastic optimal control of an unknown LTI dynamical system. Assuming the process noise is normally distributed, we pose the problem of ste…
