Modeling and Predicting Epidemic Spread: A Gaussian Process Regression Approach

no code implementations14 Dec 2023 Baike She, Lei Xin, Philip E. Paré, Matthew Hale

Gaussian Process Regression excels in using small datasets and providing uncertainty bounds, and both of these properties are critical in modeling and predicting epidemic spreading processes with limited data.

Differentially Private Reward Functions for Markov Decision Processes

no code implementations21 Sep 2023 Alexander Benvenuti, Calvin Hawkins, Brandon Fallin, Bo Chen, Brendan Bialy, Miriam Dennis, Matthew Hale

We then develop an algorithm for the numerical computation of the performance loss due to privacy on a case-by-case basis.

Privacy-Engineered Value Decomposition Networks for Cooperative Multi-Agent Reinforcement Learning

no code implementations13 Sep 2023 Parham Gohari, Matthew Hale, Ufuk Topcu

Accordingly, we propose Privacy-Engineered Value Decomposition Networks (PE-VDN), a Co-MARL algorithm that models multi-agent coordination while provably safeguarding the confidentiality of the agents' environment interaction data.

Characterizing Compositionality of LQR from the Categorical Perspective

no code implementations2 May 2023 Baike She, Tyler Hanks, James Fairbanks, Matthew Hale

Then we develop new sufficient conditions to guarantee that the LQR designed for a composite system is equal to the LQR attained through composition of LQRs for its subsystems.

DOMINO: Domain-aware Loss for Deep Learning Calibration

1 code implementation10 Feb 2023 Skylar E. Stolte, Kyle Volle, Aprinda Indahlastari, Alejandro Albizu, Adam J. Woods, Kevin Brink, Matthew Hale, Ruogu Fang

Deep learning has achieved the state-of-the-art performance across medical imaging tasks; however, model calibration is often not considered.

Differential Privacy in Cooperative Multiagent Planning

1 code implementation20 Jan 2023 Bo Chen, Calvin Hawkins, Mustafa O. Karabag, Cyrus Neary, Matthew Hale, Ufuk Topcu

We synthesize policies that are robust to privacy by reducing the value of the total correlation.

Distributed Reproduction Numbers of Networked Epidemics

no code implementations19 Jan 2023 Baike She, Philip E. Paré, Matthew Hale

These conditions are then used to derive new conditions for the existence, uniqueness, and stability of equilibrium states.

Fast Verification of Control Barrier Functions via Linear Programming

no code implementations1 Dec 2022 Ellie Pond, Matthew Hale

Targeting the latter problem, this paper presents a method of verifying any finite number of candidate control barrier functions with linear programming.

DOMINO: Domain-aware Model Calibration in Medical Image Segmentation

1 code implementation13 Sep 2022 Skylar E. Stolte, Kyle Volle, Aprinda Indahlastari, Alejandro Albizu, Adam J. Woods, Kevin Brink, Matthew Hale, Ruogu Fang

Our experiments demonstrate that our DOMINO-calibrated deep neural networks outperform non-calibrated models and state-of-the-art morphometric methods in head image segmentation.

Privacy-Preserving Kickstarting Deep Reinforcement Learning with Privacy-Aware Learners

no code implementations18 Feb 2021 Parham Gohari, Bo Chen, Bo Wu, Matthew Hale, Ufuk Topcu

We then develop a kickstarted deep reinforcement learning algorithm for the student that is privacy-aware because we calibrate its objective with the parameters of the teacher's privacy mechanism.
