Improved Bayes Method Based on TF-IDF Feature and Grade Factor Feature for Chinese Information Classification

2018

Existing methods improved the accuracy of Bayes by weakening its feature independence assumption. However, these approaches only simply incorporate the learned feature into the formula of Naive Bayes, but they do not incorporate these features …

Controllable Switching between Superradiant and Subradiant States in a 10-qubit Superconducting Circuit

2020 · Physical Review Letters

Superradiance and subradiance concerning enhanced and inhibited collective radiation of an ensemble of atoms have been a central topic in quantum optics. However, precise generation and control of these states remain challenging. Here we deterministically …

Observation of critical phase transition in a generalized Aubry-André-Harper model on a superconducting quantum processor with tunable couplers

2022 · arXiv (Cornell University)

Quantum simulation enables study of many-body systems in non-equilibrium by mapping to a controllable quantum system, providing a new tool for computational intractable problems. Here, using a programmable quantum processor with a chain of 10 …

AndesVL Technical Report: An Efficient Mobile-side Multimodal Large Language Model

2025 · arXiv (Cornell University)

In recent years, while cloud-based MLLMs such as QwenVL, InternVL, GPT-4o, Gemini, and Claude Sonnet have demonstrated outstanding performance with enormous model sizes reaching hundreds of billions of parameters, they significantly surpass the limitations in …

Multimode Purcell filter for superconducting-qubit reset and readout with intrinsic Purcell protection

2026 · Physical Review Applied

Efficient qubit reset and leakage reduction are essential for scalable superconducting quantum computing, particularly in the context of quantum error correction. However, such operations often require additional on-chip components. Here, we propose and experimentally demonstrate …
