The passage around this formula
where are the teacher’s pre-softmax logits. “Using a higher value for T produces a softer probability distribution over classes” [ 4 ] , and it is precisely that softness — the relative probabilities the teacher assigns to the wrong answers, not only the single correct label — that carries information a hard label discards: how confidently a teacher model preferred one wrong answer over another says far more about the shape of its decision boundary than one correct label does. The paper states the mechanism directly: “Knowledge is transferred to the distilled model by training it on a transfer set and using a soft target distribution for each case in the transfer set that is produced by…
