New Framework Explains Linear Representation Formation in LLMs

Researchers have introduced the Spectral Principal Path (SPP) framework to explain how linear representations form in large language models (LLMs). This framework is based on the Input-Space Linearity Hypothesis, which suggests that concept-aligned directions originate in the input space and are maintained through network layers. The SPP framework provides theoretical stability guarantees and identifies conditions like spectral gap and context incoherence that preserve these directions, offering potential implications for AI fairness and transparency.
