SMELT architecture improves MoE Transformer training efficiency

By PulseAugur Editorial · [2 sources] ·

Researchers have developed SMELT, a new architecture for Mixture-of-Experts (MoE) Transformers that improves training efficiency and downstream performance. By looping the middle layers of the transformer twice while carefully matching computational budgets, SMELT demonstrates faster loss reduction and significant savings in training FLOPs compared to baseline models. This architectural improvement translates to better performance on various benchmarks, particularly in code-related tasks, and is attributed to a mechanism that redirects attention to more relevant tokens.
