Formal Abstraction of General Stochastic Systems via Noise Partitioning

no code implementations19 Sep 2023 John Skovbekk, Luca Laurenti, Eric Frew, Morteza Lahijanian

We introduce a general procedure for the finite abstraction of nonlinear stochastic systems with non-standard (e. g., non-affine, non-symmetric, non-unimodal) noise distributions for verification purposes.

Formal Verification of Unknown Dynamical Systems via Gaussian Process Regression

no code implementations31 Dec 2021 John Jackson, Luca Laurenti, Eric Frew, Morteza Lahijanian

In this article, we develop a framework for verifying partially-observable, discrete-time dynamical systems with unmodelled dynamics against temporal logic specifications from a given input-output dataset.

Synergistic Offline-Online Control Synthesis via Local Gaussian Process Regression

no code implementations11 Oct 2021 John Jackson, Luca Laurenti, Eric Frew, Morteza Lahijanian

The online controller may improve the baseline guarantees since it avoids the discretization error and reduces regression error as new data is collected.

Strategy Synthesis for Partially-known Switched Stochastic Systems

no code implementations5 Apr 2021 John Jackson, Luca Laurenti, Eric Frew, Morteza Lahijanian

We present a data-driven framework for strategy synthesis for partially-known switched stochastic systems.

Factorized Machine Self-Confidence for Decision-Making Agents

1 code implementation15 Oct 2018 Brett W. Israelsen, Nisar R. Ahmed, Eric Frew, Dale Lawrence, Brian Argrow

Markov decision processes underlie much of the theory of reinforcement learning, and are commonly used for planning and decision making under uncertainty in robotics and autonomous systems.
