How can a Radar Mask its Cognition?

no code implementations20 Oct 2022 Kunal Pattanayak, Vikram Krishnamurthy, Christopher Berry

We provide theoretical guarantees by ensuring the Type-I error probability of the adversary's detector exceeds a pre-defined level for a specified tolerance on the radar's performance loss.

Inverse-Inverse Reinforcement Learning. How to Hide Strategy from an Adversarial Inverse Reinforcement Learner

no code implementations22 May 2022 Kunal Pattanayak, Vikram Krishnamurthy, Christopher Berry

In this paper, we consider how an agent can hide its strategy and mitigate an adversarial IRL attack; we call this inverse IRL (I-IRL).

How can a Cognitive Radar Mask its Cognition?

no code implementations16 Oct 2021 Kunal Pattanayak, Vikram Krishnamurthy, Christopher Berry

In turn, the radar deliberately chooses sub-optimal responses so that its utility function almost fails the utility maximization test, and hence, its cognitive ability is masked from the adversary.

Dirichlet Process Gaussian-mixture model: An application to localizing coalescing binary neutron stars with gravitational-wave observations

1 code implementation24 Jan 2018 Walter Del Pozzo, Christopher Berry, Archisman Ghosh, Tom Haines, Leo Singer, Alberto Vecchio

We reconstruct posterior distributions for the position (sky area and distance) of a simulated set of binary neutron-star gravitational-waves signals observed with Advanced LIGO and Advanced Virgo.
