Technical principles of Yuan 2.0-M32
- Attention Router: Unlike traditional routing algorithms, Attention Router introduces an attention mechanism to consider the collaborative relationships between different experts, optimizes the expert selection process, and improves the model's accuracy.
- Localized Filtering-based Attention (LFA): LFA enhances the model's ability to understand local and global features of natural language by learning the local dependencies between input tokens.
- Efficient training strategy: It combines data parallelism and pipeline parallelism training methods, avoiding the use of tensor parallelism or optimizer parallelism, and reducing communication overhead during training.
- Refined fine-tuning method: During the fine-tuning stage, the model supports longer sequence lengths and adjusts the base frequency value of RoPE (Rotary Position Embedding) as needed to adapt to longer contexts.
