2026Recent advancement in vision-language models have enabled multi-modal person re-identification (Re-ID), where the system takes both an image and a text query to identify matching individuals. While previous state-of-the-art methods perform well with detailed, sentence-level descriptions, we found that their Recall@1 drops by half when using short, keyword-based queries due to ambiguity, training biases,

KDD 2026 Workshop on Evaluation and Trustworthiness of Agentic AI2026Evaluating multi-step diagnostic reasoning in LLM agents remains an open problem. When cause labels are extracted from resolved operational cases (customer-service tickets, incident reports, clinical notes), the resulting gold standards exhibit extreme vocabulary explosion—5,076 unique cause strings from 2,196 tickets on a single symptom, 92% appearing only once—making LLM-as-judge protocols variance-prone

IEEE/ACM 2026 International Conference on Automated Software Engineering (ASE 2026)2026At Amazon Prime Video, we face the critical operational challenge of managing code deployments during live events and rapid feature releases without causing service outages. Current change control approaches use blanket deployment freezes that block all changes regardless of risk, creating significant developer toil. While prior re-search has explored risky change predictors, these rely on developer-specific

COLM 20262026Recent work identified Super Weights, individual parameters whose removal degrades model performance by orders of magnitude. We show that this degradation due to pruning Super Weights does not universally apply to all LLMs. Furthermore, if these parameters are so important, Super Weight-aware training should be effective. We show the opposite. Training Super Weights in isolation (100 to 8,192 parameters

ICML 2026 Workshop on Agents in the Wild2026Reward hacking arises when a model improves a proxy reward by exploiting shortcuts rather than solving the intended task. We study this failure mode through the geometry of reinforcement learning updates in language models and argue that hacking emerges when optimization drifts away from a stable low-dimensional learning trajectory. We analyze this drift through dominant singular directions of parameter
