模型信息 Model Information

基于Erlangshen-MegatronBert-1.3B,我们在收集的20个中文领域的改写数据集,总计2,773,880个样本上微调了一个Similarity版本。

Based on Erlangshen-MegatronBert-1.3B, we fine-tuned a similarity version on 20 Chinese paraphrase datasets, with totaling 2,773,880 samples.

成就 Achievements

我们于2022年7月10日登顶CLUE语义匹配榜,详情见Towards No.1 in CLUE Semantic Matching Challenge: Pre-trained Language Model Erlangshen with Propensity-Corrected Loss

We topped the CLUE benchmark semantic matching task on July 10, 2022, as detailed in Towards No.1 in CLUE Semantic Matching Challenge: Pre-trained Language Model Erlangshen with Propensity-Corrected Loss.
