Robust and efficient algorithms for high-dimensional black-box quantum optimization
Zhaoqi Leng, Pranav Mundada, Saeed Ghadimi +1
Hybrid quantum-classical optimization using near-term quantum technology is an emerging direction for exploring quantum advantage in high-dimensional systems. However, precise char…
Multi-Point Bandit Algorithms for Nonstationary Online Nonconvex Optimization
Abhishek Roy, Krishnakumar Balasubramanian, Saeed Ghadimi +1
Bandit algorithms have been predominantly analyzed in the convex setting with function-value based stationary regret as the performance measure. In this paper, motivated by online…
Stochastic Zeroth-order Discretizations of Langevin Diffusions for Bayesian Inference
Abhishek Roy, Lingqing Shen, Krishnakumar Balasubramanian +1
Discretizations of Langevin diffusions provide a powerful method for sampling and Bayesian inference. However, such discretizations require evaluation of the gradient of the potent…
