Features
Knowledge Inheritance
Exploite existing model knowledge to accelerate training
Prompt Tuning
Use prompts to tune the model, which reduces the tuning parameters and better stimulates model performance
Mixture of Experts
The model parameters can be expanded by MoE to support the training of the hundred-billion scale model
Performance
CPM2 has strong general language intelligence
Performance of mT5 and CPM-2 with fine-tuning. We use the first 6 datasets, which makes up the lite version of CUGE, to compute the overall CUGE scores (%). The numbers in brackets are the CUEG scores (%) for each dataset.
