This work formalizes influence as a counterfactual estimand, distinguishes specification mismatch across estimands from approximation error in estimating a fixed estimand, and organizes representative estimators by their implied specifications.

A typed domain-specific language that captures recurring tensor structures, such as repeated regions and floating-point fields, through a set of reversible operators, is designed, which formulates lossless tensor compression as program synthesis.

This work constructs a cross-effect matrix over a taxonomy of 67 behaviors across three open-weight language models and shows that side effects are largely predictable before steering is performed, enabling proactive safety auditing and more informed deployment of steering interventions.

A training-free defense that first identifies safety-specific neurons through per-neuron hypothesis tests under false-discovery-rate control together with a utility-specificity filter, and reduces the average attack success rate to at most 2.0% while incurring a utility drop of only 0.3% on MT-Bench, the smallest among...
