    Definition

    Online distillation generates teacher and student signals within the same training process.

    Distillation where teacher and student signals emerge jointly during the same training process or models learn from each other.

    Simply explained

    Multiple models learn from each other during training instead of following only a pre-trained teacher.

    Why it matters in practice

    Helps realistically assess model quality, limits, and technical decisions.

    Example from business

    Multiple models exchange soft target distributions during training.

    Limits and pitfalls

    • Confusing online distillation with streaming learning or ignoring unstable mutual error amplification.

    Origin & history

    Deep Mutual Learning from 2018 is a well-known approach without a fixed pre-trained teacher model.

    Use in mid-sized companies

    • Possible application: Multiple models exchange soft target distributions during training.
