Compositional Literary Primitives in Instruction-Tuned LLMs: Cross-Architectural SAE Features for Self, Style, and Affect
The paper discusses a compositional architecture of literary primitives in instruction-tuned large language models. It identifies four feature classes that enhance emotional expression and stylistic modulation in the models Llama and Gemma. The study employs a validation pipeline to assess the models' performance in generating affect-categorizable outputs.
- ▪The study characterizes literary primitives in two instruction-tuned large language models, Llama and Gemma.
- ▪Four feature classes were identified, including naming-gates and stylistic register modulators.
- ▪Llama achieved full coverage of a 27-category emotion taxonomy, while Gemma reached 23 out of 27.
