模型信息 Model Information

遵循Longformer-base的设计,我们基于chinese_roformer_L-12_H-768_A-12,在悟道语料库(180 GB版本)上进行了继续预训练。特别的,我们采用旋转位置嵌入(RoPE)来避免预训练语料库的不均匀序列长度问题。

Following the design of Longformer-base, we performed continual pre-training on the WuDao corpus (180 GB) based on chinese_roformer_L-12_H-768_A-12. Particularly, we employed rotational position embedding (RoPE) to avoid the uneven sequence length of the pre-trained corpus.

使用 Usage


Since there is no structure of Longformer-base in transformers library, you can find the structure of Longformer-base and run the codes in Fengshenbang-LM.

git clone https://github.com/IDEA-CCNL/Fengshenbang-LM.git
