Transformer Circuits: Dissecting a Counting Task via the Geometry of Learned Manifolds

burny_tech · x · 2026-10-27

Transformer Circuits published a new thread, "When Models Manipulate Manifolds: The Geometry of a Counting Task," reverse-engineering learned representations for a counting task through the lens of manifold geometry. The author notes that from a pure single-neuron interpretability view, the manifold perspective on learned representations (as used in manifold steering) is missing, along with learned distributed circuits composed of more specific algorithms, such as learned Fourier circuits for arithmetic.
