Mechanomyography-Based Closed-Loop Control of FES Enabling Prolonged Force Assistance by Monitoring Muscle Fatigue

ICRA 2026poster

Functional Electrical Stimulation (FES) is a critical therapy for motor rehabilitation, yet the rapid onset of muscle fatigue severely limits its efficacy. This paper presents the design, implementation, and validation of a comprehensive, intelligent closed-loop FES system designed to provide effect…

Model-Agnostic Sentiment Distribution Stability Analysis for Robust LLM-Generated Texts Detection

AAAI 2026technical

The rapid advancement of large language models (LLMs) has resulted in increasingly sophisticated AI-generated content, posing significant challenges in distinguishing LLM-generated text from human-written language. Existing detection methods, primarily based on lexical heuristics or fine-tuned class

TopoDistill: Distilling Global System Topology for Causal Discovery in Multivariate Time Series

ICML 2026poster

Although causal discovery from multivariate time series is widely used, it remains challenging under noise. Convergent cross mapping (CCM) infers causality by reconstructing shadow manifolds via time-delay embedding (TDE) and evaluating cross-map skill between manifolds. Despite Takens’ theorem guar…

GCAD: Anomaly Detection in Multivariate Time Series from the Perspective of Granger Causality

AAAI 2025technical

Multivariate time series anomaly detection has numerous real-world applications and is being extensively studied. Modeling pairwise correlations between variables is crucial. Existing methods employ learnable graph structures and graph neural networks to explicitly model the spatial dependencies bet…

ZeCO: Zero-Communication Overhead Sequence Parallelism for Linear Attention

NeurIPS 2025poster

Linear attention mechanisms deliver significant advantages for Large Language Models (LLMs) by providing linear computational complexity, enabling efficient processing of ultra-long sequences (e.g., 1M context). However, existing Sequence Parallelism (SP) methods, essential for distributing these wo…
