Activation probing trains a linear classifier on the activations of one or several layers of the model to predict faithfulness; it is a static, single-point detection that struggles to capture inter-layer dynamics.

UnverifiedTraditional linear probes use maximizing concept classification accuracy as the training objective, without distinguishing whether directions have causal influence.80% similarUnverifiedThe action probe draws on the linear probing method from the self-supervised learning field, whose basic idea is to freeze the model backbone representation and train only a lightweight classifier or regressor on top of it, attempting to recover the target information from the frozen features.76% similarUnverifiedApplication-layer jailbreak defenses must simultaneously rely on robustness improvements at the training stage and dynamic monitoring at the inference stage, as reinforcement along a single dimension yields limited results.75% similarUnverifiedConformal prediction relies on two key concepts: nonconformity scores and a calibration set, where the calibration set is data with true labels that is independent of the training set.75% similarUnverifiedExamining the model's action sequences during training one by one can determine whether high scores result from genuine capability improvement or from exploiting loopholes in the reward mechanism.74% similar
