ConflictVLA-Bench：评估视觉-语言-动作模型对前提冲突的行为反应
ConflictVLA-Bench: Benchmarking Behavioral Responses of Vision-Language-Action Models to Premise Conflicts
arXiv:2609.31792v1 公告类型：新 摘要：视觉-语言-动作（VLA）模型在操作任务上表现强劲，但其对无效任务前提的反应仍未被充分探索。现有对前提冲突的评估往往聚焦于最终任务结果，然而仅凭任务失败无法区分行为脱离与继续追求随后出现执行错误。我们将后一种模式称为“失败坚持”（Failed Persistence）。为研究这一现象，我们提出 ConflictVLA-Bench，它将冲突 rollout 与前提一致的参考 rol…

深度粗糙波动率中的不确定性与可解释性：神经信息论后验方法
Uncertainty and Explainability in Deep Rough Volatility: A Neural Information-Theoretic Posterior Approach
摘要显示，该研究提出基于模拟推断的粗糙 Heston（rHeston）校准框架，利用神经比率估计学习隐含波动率曲面条件下的参数后验分布，并将后验样本传播至异方差神经代理定价器，得到融合参数残差不确定性与代理条件不确定性的后验预测价格区间。作者还提出 Hellinger-SHAP，一种以后验信息泛函为对象的可解释性方法，用于识别各参数信息增益对应的期限-行权价区域。模拟研究表明，后验预测区间在远期启动、障碍与方差互换类合约上覆盖率合理或保…
意义：为波动率模型校准提供不确定性量化与可解释性工具，提示开发者仅用点估计定价可能不可靠，需关注后验预测区间。
