  • The core analytical technique of expanding transformer computations from layer-by-layer products into sums of end-to-end path terms for independent analysis
  • Neural circuit motif selecting the strongest input; approximated by softmax.
  • The idea that living structure emerges only through a sequence of small, structure-preserving moves, not by a single grand blueprint.
  • The path in activation space derived by fitting the representation manifold, used to steer along the geometric structure of internal representations.
  • Gradient methodmethod0.703
    Optimization technique that computes weight changes by following the gradient of an error function; contrasted with evolutionary stochastic search.
  • The number of distinct paths information can travel from point A to B in a transformer is C(m+n, n), quickly exceeding the number of atoms in the universe.
