😎 What's Interesting?

Dynamic Mixture of Experts (DynMoE) incorporates (1) a novel gating method that enables each token to automatically determine the number of experts to activate. (2) An adaptive process automatically adjusts the number of experts during training.

Top-Any Gating

💡 Model Details

• 🤔 DynMoE-Phi-2 is a MoE model with dynamic top-k gating, finetuned on LanguageBind/MoE-LLaVA-Phi2-Stage2.
• 🚀 Our DynMoE-Phi-2-2.7B has totally 5.3B parameters, but only 3.4B are activated! (average top-k = 1.68)
• ⌛ With the DynMoE tuning stage, we can complete training on 8 A100 GPUs within 2 days.
