Trajectory-Guided Tokenization of Complex CSI for Wi-Fi Sensing

Ziyi Wang, Kenuo Xu, Jichu Jiang وآخرون · 2026

Wi-Fi channel state information (CSI) enables contactless presence detection and gesture recognition. Its high-dimensional complex-valued time series require input representations that preserve informative temporal variations during compression. We propose Trajectory-Guided Tokenization (TGT), which combines complex tr …

SecJev: Bringing Security Expertise to System One Decision Models

Zheng Chen, Fei Yu, Haohao Huang وآخرون · 2026

Security workflows need models that turn complex observations and explicit policies into decisions. System One models introduced by Jev return typed predictions and probabilities; security specialization supplies the domain expertise behind those predictions. We introduce SecJev, to our knowledge the first family of Je …

RankEvolve: A Reliable Multi-Agent Auto-Research Harness for Evolving Ranking Models

Zheng Chen, Linfeng Liu, Hong Li وآخرون · 2026

Auto-research agents, LLM systems that propose, implement, train, and evaluate model changes across iterations, promise to automate applied ML's experimental loop. Over long horizons, execution accuracy is a binding constraint: a change can silently leak held-out data, omit normalization, disconnect a gradient, or leav …

RL-PaO: Prediction as Action in Decision Making under Uncertainty

Jiahui Feng, Dafang Zhao, Zheng Chen وآخرون · 2026

Decision-making under uncertainty often relies on predicted parameters, yet accurate prediction does not necessarily lead to good operational decisions. Aligning prediction with downstream optimization requires learning from the consequences of the decisions those predictions induce. We introduce RL-PaO, a reinforcemen …

GRFBrain: Graph-Structured Rectified Flows for EEG Dynamic Modeling

Forecasting time-varying functional connectivity from electroencephalography (EEG) requires modeling both history-dependent trends and structured variability across channels. Conditional flow matching provides a framework for distributional forecasting, yet it remains unclear whether graph-informed source distributions …

Syndrome, Synergy, and Safety: Structured Reasoning and Knowledge-Driven Alignment for TCM Prescription Generation

Zheng Chen, ZhiCheng Du, Haoxuan Li وآخرون · 2026

Applying large language models to Traditional Chinese Medicine (TCM) prescription generation reveals three clinically critical gaps: models produce end-to-end mappings without auditable reasoning following the li-fa-fang-yao paradigm (SR Gap), treat each encounter in isolation without follow-up adjustment via sui zheng …

SPHQuant: Efficient extreme low bit weight quantization for Vision-Language Models

Kewei Zhang, Zheng Chen, Haotong Qin وآخرون · 2026

Recent foundation models are moving toward native multimodal Vision-Language Models (VLMs), making VLMs a central form of next-generation foundation models. However, their large language backbones make edge deployment difficult due to high memory footprint and memory-bound autoregressive decoding. Weight-only post-trai …

TrialAtlas: Multi-Agent Research Organization for Clinical Trial Design and Optimization

Jiacheng Lin, Zifeng Wang, Zheng Chen وآخرون · 2026

Nearly 90% of drugs entering clinical development ultimately fail, despite billions of dollars in investment. Pharmaceutical companies therefore rely on clinical development planning (CDP) and probability of technical and regulatory success assessment to anticipate development risks, yet these decisions remain labor-in …
