What the article says around this equation
Hinton, Vinyals and Dean’s 2015 paper, “Distilling the Knowledge in a Neural Network,” is the one the field actually cites, and it earned that position by generalizing the 2006 idea and giving it a mechanism simple enough to fit into any neural network’s training pipeline. Instead of training a small model against a large model’s hard output labels, distillation trains it against the large “teacher” model’s full, softened probability distribution over classes — the softmax output computed at a raised temperature T :
