ShopGym converts live e-commerce sites into reproducible simulated shops and synthesizes diverse benchmark tasks, showing synthetic shops preserve live structural properties and agent performance correlations.
History-Aware Prediction Sets (HAPS) construct conformal prediction sets for censored time-to-event outcomes using time-varying covariate histories, reducing interval lengths up to 75% while maintaining coverage among survivors.
Null-space projection of LoRA updates removes backdoors from fine-tuned LLMs without retraining or clean data, cutting attack success below 10% while preserving downstream skills.
Latent visual reasoning enhances multimodal training despite being largely unused at inference; attention-based reinforcement learning preserves its benefits by promoting latent-text interaction during training.
Standardized item-level benchmark releases should become AI evaluation infrastructure because aggregate scores obscure validity failures; OpenEval archives 10M responses to enable auditability and recover benchmark validity evidence.
PromptMIA uses adversarial soft prompts to exploit federated prompt-tuning updates for highly effective membership inference attacks that bypass standard defenses.
Intent-obfuscation jailbreaks on MLLMs face a reconstruction-concealment tradeoff that existing transformations fail to balance, but character-removed variants and concealment-aware construction with keyword distractor images exploit model reconstruction to bypass safety filters.
