AI总结 针对提示注入检测器异构且不可靠的问题,提出SCOUT框架,通过预测每个检测器对每个样本的可靠性和延迟,动态分配检测器,实现安全性与效率的权衡。
Comments We propose SCOUT, a detector allocation framework that predicts each detector's accuracy and latency on a given input before running it, letting operators control the safety-utility trade-off with a single threshold and route to an LLM judge only when needed
