The round

Start with a gradient-descent calculation, then explain momentum, adaptive scaling and the state retained by AdamW. The round also covers bias correction, weight decay and learning-rate warmup. Each question asks for a concise explanation of the mechanism.

Concepts and calculations
Answer in prose or use equivalent mathematical notation. You do not need to write or run training code.

What you'll practise

  • Parameter updates

    Reason about gradient-descent behaviour and the influence of earlier gradients.

  • Adaptive optimizers

    Explain gradient history, optimizer state and bias correction.

  • Training choices

    Distinguish weight-decay mechanisms and explain the purpose of warmup.
