Aligning Multimodal Patient Evidence with Biomedical Knowledge Graphs for Clinical LLMs

Jiawen Du, Arshan Ali Khan, Chenhao Zhang وآخرون · 2026

Clinical questions often depend on linking a patient's multimodal evidence to external biomedical knowledge, yet existing predictive systems rarely represent such links explicitly, so they can neither be traced to their evidence sources nor removed to measure their contributions. We present MM-KG (Multimodal Knowledge …

On the Divergence of Accuracy and Mechanism Consistency in Time Series World Models

Haochen Zhang, Jiaheng Guo, Zhen Xu وآخرون · 2026

A time series world model (TSWM) predicts a controlled system's state from its observed history and planned actions and exogenous inputs. Current approaches build forecasters with actions as covariates, trained and evaluated on prediction error under the executed plan. Yet world models compare unexecuted plans, but the …

No Scale Left Behind: Multi-Scale Autoencoder with Bi-directional Attention for Time Series Anomaly Detection

Jiaheng Guo, Haochen Zhang, Yu-Chao Huang وآخرون · 2026

Time series anomaly detection (TSAD) plays a crucial role in healthcare, finance, industrial monitoring, and other sectors. Within and between these settings, anomalies span vastly different temporal scales, from sub-second point spikes to multi-hour drift patterns. However, most existing TSAD methods commit to a singl …
