Adaptive ECCM for Mitigating Smart Jammers

no code implementations5 Dec 2022 Kunal Pattanayak, Shashwat Jain, Vikram Krishnamurthy, Chris Berry

This paper considers adaptive radar electronic counter-counter measures (ECCM) to mitigate ECM by an adversarial jammer.

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.

Unifying Revealed Preference and Revealed Rational Inattention

no code implementations28 Jun 2021 Kunal Pattanayak, Vikram Krishnamurthy

Second, we exploit the unification result computationally to extend robustness measures for goodness-of-fit of revealed preference tests in the literature to revealed rational inattention.

Rationally Inattentive Utility Maximization for Interpretable Deep Image Classification

1 code implementation9 Feb 2021 Kunal Pattanayak, Vikram Krishnamurthy

Are deep convolutional neural networks (CNNs) for image classification explainable by utility maximization with information acquisition costs?

Adversarial Radar Inference: Inverse Tracking, Identifying Cognition and Designing Smart Interference

no code implementations1 Aug 2020 Vikram Krishnamurthy, Kunal Pattanayak, Sandeep Gogineni, Bosung Kang, Muralidhar Rangaswamy

The levels of abstraction range from smart interference design based on Wiener filters (at the pulse/waveform level), inverse Kalman filters at the tracking level and revealed preferences for identifying utility maximization at the systems level.

Rationally Inattentive Inverse Reinforcement Learning Explains YouTube Commenting Behavior

2 code implementations24 Oct 2019 William Hoiles, Vikram Krishnamurthy, Kunal Pattanayak

We consider a novel application of inverse reinforcement learning with behavioral economics constraints to model, learn and predict the commenting behavior of YouTube viewers.
