PISA 2025 Students' reading and mathematics performance declined across the OECD
Summary
The article explores using Jacobian space (J Space) to derive activation steering vectors for LLMs, testing with Qwen3-1.7B, and discusses baseline steering, all-caps output, and refusal behavior, noting instability and hallucinations. It outlines a practical approach to constructing refusal vectors and highlights limitations of token-based steering for complex behaviors.
