Papers with second-moment estimates
CAME: Confidence-guided Adaptive Memory Efficient Optimization (2023.acl-long)
Copied to clipboard
| Challenge: | Existing memory-efficient methods require second-moment estimates of the per-parameter gradients to maintain their performance. |
| Approach: | They propose to use memory-efficient optimizers to reduce memory usage by preserving second-moment estimates of gradients. |
| Outcome: | The proposed method achieves fast convergence and lower memory usage across training tasks. |
AdamS: Momentum Itself Can Be A Normalizer for LLM Pretraining and Post-training (2025.emnlp-main)
Copied to clipboard
| Challenge: | Empirically, AdamS demonstrates strong performance in various tasks . et al., 2023b): AdamS is efficient, efficient, and model-agnostic. |
| Approach: | They propose a model-agnostic alternative to Adam for large language model pretraining and post-training. |
| Outcome: | The proposed method matches memory footprint of SGD with momentum while delivering superior performance. |
