An Explicit Feedback Contract for Iterative ML-Agent Harnesses
Kehui Yao, Chuanbo Hu, Jiao Chen +8
Iterative ML agents develop models by editing code, running experiments, reading a validation score, and choosing what to try next. In current harnesses this loop is served by an e…
Conditional Rank Allocation for Taxonomy-Aware Medical Language Model Adaptation
Guangyuan Dong, Ziwei Hong, Xuehao Zhou +6
Medical question answering spans specialties and clinical operations that may benefit from different adaptation directions. We propose ARBOR, a parameter-efficient method that sele…
GAUDI: Geometry-Aware Diffusion for Calibrated Air-Quality Time-Series Imputation
Xinjin Li, Yudi Xia, Calvin Chang Liu +7
Air-quality sensor outages often create contiguous missing blocks, where side information useful for isolated missingness may be less reliable. We study a block-specific, GAUDI-ali…
Chain-Aware Encoding for Microservice Trace Anomaly Detection
Yiliu Xu, Ziwei Hong, Zhongheng Yang +2
Microservice traces can be structurally anomalous even when every span returns normally -- a payment flow that silently skips a risk check looks fine to any per-span monitor. Seque…
Dynamic Interaction-Aware and Causality-Disentangled Framework for Multimodal Sentiment Analysis
Guangyuan Dong, Ziwei Hong, Shenghao Liu +9
Although Multimodal Sentiment Analysis (MSA) effectively leverages rich information from language, visual, and acoustic modalities, existing methods still face two core challenges:…
CenterMamba-SAM: Center-Prioritized Scanning and Temporal Prototypes for Brain Lesion Segmentation
Yu Tian, Zhongheng Yang, Chenshi Liu +4
Brain lesion segmentation remains challenging due to small, low-contrast lesions, anisotropic sampling, and cross-slice discontinuities. We propose CenterMamba-SAM, an end-to-end f…
