Low-dimensional space of activation directions corresponding to diverse character archetypes in LLMs

Neighborhood — ranked by edge-count

framework

Assistant Axis
implements
Contrast vector between mean default Assistant activation and mean of all fully role-playing role vectors; main contribution of the paper

cosine ≥ 0.65 · no typed edge

Entities in the same semantic neighborhood but without a typed relation to this one — candidates for new edges or unrecognized duplicates.
