A Control Barrier Function Approach to Constrained Resource Allocation Problems in a Maximum Entropy Principle Framework

We develop a control-theoretic framework for solving constrained resource allocation problems, formulated as generalized facility location with optimal placement and assignment decisions. Leveraging Control Barrier Functions (CBFs), Control Lyapunov Functions (CLFs), and the Maximum Entropy Principle (MEP), our approach ensures feasibility while improving convergence and constraint handling. This work was submitted to CDC 2025, with a related poster presented at the 2025 Midwest Workshop on Control and Game Theory.

Statistical Reinforcement Learning

Instructor: Nan Jiang

Reproduced and analyzed the core results of “Regret Bounds for the Adaptive Control of Linear Quadratic Systems” by Abbasi-Yadkori and Szepesvári. This work presents key theorems, lemmas, and an algorithm designed for solving Linear Quadratic (LQ) control problems with unknown model parameters—commonly referred to as adaptive control—aiming to minimize regret. The proposed algorithm estimates parameters using high-probability confidence sets and achieves a regret bound of $\tilde{O}(\sqrt{T})$.

Computer Vision

Instructor: Svetlana Lazebnik

Developed and compared deep learning architectures (CNN, VGGNet, LeNet) for facial keypoint detection on noisy and tilted images using a Kaggle dataset. Implemented data augmentation and evaluated robustness across models using training/validation losses and visual prediction outputs.
