Quantum Sensing Beyond Exceptional Points via Hidden symmetry-protected vacuum-noise fixed point

Wencong Wang, Y. T. Liang, Peng Han, X . Wu et autres

Exceptional-point (EP) sensing has attracted considerable interest because of its anomalous response scaling. However, recent studies have shown that the enhanced response near an EP is inevitably accompanied by amplified quantum noise, fundamentally limiting the achievable signalto-noise ratio (SNR). Here, we propose …

Mamba Hawkes Process for Event Sequence Modeling

Shan Dai, Y. T. Liang, Chenhao Ma, Anningzhe Gao

Modeling asynchronous event sequences is crucial in numerous real-world applications such as healthcare monitoring, financial transaction analysis, and so on. Traditional temporal point processes, including Hawkes Processes, often fail to capture complex dependencies due to their parametric limitations. While neural approaches like …

Benchmarking Multimodal Knowledge Conflict for Large Multimodal Models

Yonghong Jia, Yuntao Du, Kailin Jiang, Y. T. Liang et autres

Large Multimodal Models (LMMs) face notable challenges when encountering multimodal knowledge conflicts, particularly under retrieval-augmented generation (RAG) frameworks, where the contextual information from external sources may contradict the model’s internal parametric knowledge, leading to unreliable outputs. However, existing benchmarks fail to reflect …

Understanding and Guiding Layer Placement in Parameter-Efficient Fine-Tuning of Large Language Models

Yichen Xu, Y. T. Liang, Shan Dai, Tianyang Hu et autres

As large language models (LLMs) continue to grow, the cost of full-parameter fine-tuning has made parameter-efficient fine-tuning (PEFT) the default strategy for downstream adaptation. Constraints from inference latency in scalable serving and fine-tuning cost in edge or rapid-deployment settings make the choice …

Realization of quadrature pseudo-PT symmetry through on-chip pure parametric gain coupling non-Hermitian devices

Wencong Wang, Y. T. Liang, Sicong Xi, peng Han et autres

On-chip non-Hermitian dynamic systems based on dissipative engineering have achieved remarkable results, but intrinsic losses and Langevin noise limit the further development of on-chip non-Hermitian devices. In this article, we propose a simple and feasible on-chip gain-gain coupling fully quantum non-Hermitian sensing …

TRACE: Intra-visit Clinical Event Nowcasting via Effective Patient Trajectory Encoding

Y. T. Liang, Yankai Chen, Yixiang Fang, Laks V. S. Lakshmanan et autres

Electronic Health Records (EHR) have become a valuable resource for a wide range of predictive tasks in healthcare. However, existing approaches have largely focused on inter-visit event predictions, overlooking the importance of intra-visit nowcasting, which provides prompt clinical insights during an ongoing …
