Technical Principles
Attention Router
The Attention Router departs from traditional routing algorithms by incorporating an attention mechanism to consider the collaborative relationships between different experts. This optimization process enhances the model’s accuracy.
Localized Filtering-based Attention (LFA)
LFA enhances the model’s understanding of both local and global features in natural language by learning the local dependencies between input tokens.
Efficient Training Strategy
The training strategy combines data parallelism and pipeline parallelism, avoiding the use of tensor parallelism or optimizer parallelism, which reduces communication overhead during training.
Fine-tuning Method
During fine-tuning, the model supports longer sequence lengths and adjusts the base frequency value of RoPE (Rotary Position Embedding) to adapt to longer contexts.
