Bootstrap Resampling over Personas

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

• Persona Reweightingconcept0.759
  The process by which fine-tuning shifts model behavior toward dark character archetypes already present in pre-trained repertoire
• Retest Consistency (persona)concept0.752
  Reproducibility of persona alignment across repeated generations for the same prompt
• Persona-model collapse and persona reweighting are not mutually exclusive but are distinct processes that can coexistclaim0.751
  Authors argue collapse is a separate process from the reweighting account, not merely a relabeling
• How can persona reweighting be mechanistically distinguished from persona-model collapse?question0.740
  Central open problem identified by the authors: the same mechanistic signatures may be consistent with both accounts
• Persona representations originate in pretraining, not alignment; they form without explicit supervision as useful features for next-token predictionclaim0.733
  Core interpretive claim providing mechanistic explanation for early persona formation
• There may exist a natural 'persona basis' characterizing the space of all model personas, with correlations between persona vectors predicting co-expression of traitshypothesis0.733
  Open question proposed by authors for future work on the dimensionality and structure of persona space
• Persona Facetsconcept0.732
  Distinct sub-expressions of a persona that shift over pretraining and vary by elicitation method
• Persona directions progressively refine during pretraining with most refinement happening early, stabilizing at later checkpointsfinding0.731
  Answers RQ2 geometrically: adjacent-checkpoint cosine similarity stays high but step-to-step movement is largest early
