Distillation as Kernel Transfer, in JAX/Flax NNX
A runnable companion: the five-run distillation experiment in JAX/Flax NNX. Train a teacher CNN, extract its class-similarity kernel S = E[softmax(z/T) softmax(z/T)ᵀ], train a student on nothing but pairwise relations (no labels, no soft targets), and measure it against the label ceiling and the random floor with a linear and a nearest-centroid probe. Every number is from a real run, with six GIFs that animate the kernel assembling, the temperature dial, the handoff, the spectrum inheritance, the probe race, and the inherited mistakes.

Distillation Is a Geometry, Not an Answer Key
Knowledge distillation has a standing puzzle: Hinton's student recognized 98.6% of the digit 3s in the test set after training on a transfer set with every 3 deleted. An answer key cannot do that, so what actually crosses the wire? This post gives dark knowledge a data type, a class-similarity kernel, and runs the experiment that isolates it: a student trained on nothing but pairwise relations, no labels, no soft targets, no class names, measured against the label-trained ceiling and the random floor. With live experiments: watch the kernel accumulate from single outputs, turn the temperature knob on how much geometry leaks, train a relational student in the page, and watch whose spectrum the student grows into.
