  • Subspace DASmethod0.757
    Extension of DAS that learns a second rotation matrix on top of a fixed first one to decompose representations into sub-representations.
  • Perturbations behaviorally null in one context but altering behavior in another due to latent divergence
  • A vector subspace that causally impacts outputs only through the sign of its values, enabling harmless magnitude divergence
  • Truth Subspaceconcept0.739
    The multi-dimensional activation subspace whose directions causally mediate truthful behavior in LLMs
  • Intervention targeting specific dimensional subsets of activation vectors rather than full representations
  • Balanced Subspacesconcept0.725
    Subspaces whose contributions to a layer's output are canceled by opposing weight values, making them non-causally active under natural inputs
  • Emotion Subspaceconcept0.725
    The subspace of activation space spanned by the 171 orthogonalized emotion probe vectors, used to measure SAE feature emotional alignment
  • Investigation of whether a distributed representation can be further decomposed into sub-representations encoding component identities.
