Asked about Distillation in practice

Why use temperature in distillation?

An answer that works

At normal temperature the teacher's distribution is very peaked, so it carries little information beyond the top label. Higher temperature spreads it out so the student can learn the relative probabilities of the other classes.

Reading an answer is not being able to give one. The section that teaches this is Distillation in practice, 4 hours of Compression & distillation.
