ConceptLRH / Linear Representation Hypothesis

Linear Representation Hypothesis

A hypothesis originating from mechanistic interpretability research on large language models, proposing that high-level semantic concepts correspond to linear subspaces in representation space. Vectors encoding different attributes can be linearly combined to compose meanings, and this is considered a general organizational principle in deep networks such as Transformers.
