Anlu: Enabling In-Context Time Series Anomaly Detection in Foundation Models via Counterfactual Supervision

Tian Lan, Yifei Gao, Yimeng Lu وآخرون · 2026

Whether a time-series pattern is anomalous often depends on the operating regime of the monitored process. A missing event can signal a fault in one regime and be routine in another, and the query alone may not reveal which regime applies. We study in-context learning (ICL) for time series anomaly detection (TSAD) thro …

Generalist Representation, Specialist Detection: TS-Router for Time-Series Anomaly Detection

Tian Lan, Yifei Gao, Yimeng Lu وآخرون · 2026

Time-series anomaly detection (TSAD) is difficult to generalize across datasets because heterogeneous temporal dynamics imply different notions of normality and favor different detection criteria. While time-series foundation models provide transferable representations, coupling them with a fixed anomaly-scoring mechan …

KUPAS MASTER: Distilling the Tacit Expertise of Master Practitioners into Agent-Ready Experience Corpora

Changmian Wang, Yuchao Ma, Xuchao Lu وآخرون · 2026

Experienced professionals know more than just facts and conclusions. They know which cues matter, why a judgment is reasonable, and which action to take. Routine work records often leave out this tacit knowledge, making it difficult for Large Language Model (LLM) agents to use professional experience effectively. We in …

What Paired Evaluations Reveal under Visual Perturbations

Yongda Wei, Chen Zhang, Yifei Wang وآخرون · 2026

Robustness evaluation must examine diverse visual perturbations, while benchmarks cover only some real-world conditions and physical testing is costly. Paired evaluations link clean and perturbed predictions for the same image, capturing changes in correctness, confidence, and acceptance beyond aggregate accuracy. We i …

ScaleMPA: Rethinking Scalable RRT* Acceleration With a Grid-Native Representation

Zilong Wang, Yuzhou Chen, Xinyue He وآخرون · 2026

Real-time motion planning remains challenging in large and high-dimensional environments. Prior acceleration of RRT* follows tree-centric state organization, which reduces per-query cost but preserves superlinear end-to-end complexity and limits parallelism through structural dependencies. This paper presents ScaleMPA, …
