The zero-initialization optimization in CFG-Zero-star is one of the core technology highlights of the project, and its main effects include:
- Improving the quality of under-trained models: Zeroing out predictions at the beginning of generation can effectively improve the sample quality of under-trained models
- process of stabilization: Addresses the problem that flow matching models can produce unstable results in the early stages of the process
- diagnostic function: When the model is significantly improved with zero initialization enabled, it can be determined that the model may have an under-training problem
This technology is particularly suited to the following scenarios:
- Models trained using small datasets
- Scenarios where limited computational resources lead to insufficient training
- Research requiring rapid validation of model performance
The zero-initialization optimization together with the improved CFG technology makes CFG-Zero-star outstanding in improving the generation quality.
