Optical neural networks (ONNs) herald a new era in information and communication technologies and have implemented various intelligent applications. In an ONN, the activation function (AF) is a crucial component determining the network performances and …

Wehrl Entropy and Entanglement Complexity of Quantum Spin Systems

2023 · arXiv (Cornell University)

The Wehrl entropy of a quantum state is the Shannon entropy of its coherent-state distribution function, and remains non-zero even for pure states. We investigate the relationship between this entropy and the many-particle quantum entanglement, …

HealthBridge: A Decentralized and Interoperable Healthcare App for Rare Disease Communities

2023

Traditional centralized database systems share many weaknesses, including the overhead of sharing medical documentation, data fragmentation, and susceptibility to centralized data attacks. Those problems would especially influence rare disease patient communities given their higher need …

Trustworthy Alignment of Retrieval-Augmented Large Language Models via Reinforcement Learning

2024 · arXiv (Cornell University)

Trustworthiness is an essential prerequisite for the real-world application of large language models. In this paper, we focus on the trustworthiness of language models with respect to retrieval augmentation. Despite being supported with external evidence, …
