Rethinking Normalization Placement for LLMs: Post-Norm under Curriculum Depth Growing
TL;DR
This study investigates normalization placement in large language models (LLMs) during curriculum depth growth. It finds that post-norm outperforms pre-norm significantly when new blocks are added, suggesting a need to reconsider design choices in model training.
✦ Why It Matters
Consider adjusting normalization strategies in your LLM training to enhance performance during curriculum growth.
Key Takeaways
- Experiment with post-norm normalization in LLMs for better performance.
- Incorporate curriculum depth growth in model training strategies.
- Monitor residual scales to optimize model stability.
- Reevaluate normalization strategies as model complexity increases.
How It Works
The study demonstrates that post-norm normalization leads to more stable learning dynamics when new layers are added to a model. This stability is attributed to the way post-norm maintains consistent residual scales, which helps in managing the flow of information through deeper architectures.
