Getting the Best Out of Both Worlds: Algorithms for Hierarchical Inference at the Edge
Published 2024-01-01“…For a full feedback scenario, where the ED receives feedback on the correctness of the S-ML once it accepts the inference, we propose the HIL-F algorithm and prove a sublinear regret bound <inline-formula> <tex-math notation="LaTeX">$\sqrt {n\ln (1/\lambda _{\text {min}})/2}$ </tex-math></inline-formula> without any assumption on the smoothness of the loss function, where <inline-formula> <tex-math notation="LaTeX">$n$ </tex-math></inline-formula> is the number of data samples and <inline-formula> <tex-math notation="LaTeX">$\lambda _{\text {min}}$ </tex-math></inline-formula> is the minimum difference between any two distinct maximum probability values across the data samples. …”

Heisenberg-Limited Adaptive Gradient Estimation for Multiple Observables
Published 2025-04-01“…This remarkably achieves the scaling of Heisenberg limit 1/ε, a fundamental bound on the estimation precision in terms of mean squared error, together with the sublinear scaling of the number of observables M. The proposed method is an adaptive version of the quantum gradient-estimation algorithm and has a resource-efficient implementation due to its adaptiveness. …”
