Tame Riemannian Stochastic Approximation

2023 · arXiv (Cornell University)

We study the properties of stochastic approximation applied to a tame nondifferentiable function subject to constraints defined by a Riemannian manifold. The objective landscape of tame functions, arising in o-minimal topology extended to a geometric …

Taming Binarized Neural Networks and Mixed-Integer Programs

2024 · Proceedings of the AAAI Conference on Artificial Intelligence

There has been a great deal of recent interest in binarized neural networks, especially because of their explainability. At the same time, automatic differentiation algorithms such as backpropagation fail for binarized neural networks, which limits …

Topological quantum compilation of two-qubit gates

2024 · Physical Review A

We investigate the topological quantum compilation of two-qubit operations within a system of Fibonacci anyons. Our primary goal is to generate gates that are approximately leakage-free and equivalent to the controlled-not (cnot) gate up to …
