模型信息 Model Information
数据准备 Corpus Preparation
因果语料库：同Randeng-TransformerXL-5B-Deduction-Chinese，基于悟道语料库（280G版本），通过关联词匹配、人工标注 + GTSFactory筛选、数据清洗等步骤获取的具有因果关系的句子对
重构NLI数据：对CMNLI、OCNLI数据集进行数据清洗，并将“蕴含”类别作为正例、其余类别作为负例转换为二分类数据集
预热数据集：以重构后的CMNLI数据集为基础，引入因果语料库样本平衡正负例数量
Wudao Causal Corpus: Based on the Wudao corpus (280G version), sentence pairs with causality were obtained through logic indicator matching, manual annotation + GTSFactory, and data cleaning.
Reconstructed NLI data: After cleaning cmnli and ocnli dataset, we converted them into binary datasets by taking the "Entail" category as positive category and others as the negative.
Warm-up dataset: Based on the reconstructed cmnli dataset, the number of each category is balanced using data from the Wudao Causal Corpus.
模型训练 Model Training
- 基于chinese-roberta-wwm-ext-large模型，在预热数据集上微调预热
- 作为判别模型与Randeng-TransformerXL-5B-Deduction-Chinese模型和Randeng-TransformerXL-5B-Abduction-Chinese模型进行自洽（Self-consistent）闭环训练：
- 将预热数据集中样本的句子对拆散，分别作为原因和结果输入至Randeng-TransformerXL-5B-Deduction-Chinese模型和Randeng-TransformerXL-5B-Abduction-Chinese模型。两个生成模型基于核采样和贪心的方式进行因果推理和反绎推理，产生大量伪样本；
- 本模型对伪样本句子对的因果关系进行打分，筛选供自身以及生成模型训练的样本
First, we fine-tuned chinese-roberta-wwm-ext-large model on our warm-up dataset. Then, we conducted self-consistent learning on this model, cooperating with Randeng-TransformerXL-5B-Deduction-Chinese model and Randeng-TransformerXL-5B-Abduction-Chinese model. Specifically, sentence pairs in the warm-up dataset were split and feed into Randeng-TransformerXL-5B-Deduction-Chinese model and Randeng-TransformerXL-5B-Abduction-Chinese model as premise and result respectively. Two generative models performed deductive reasoning and abductive reasoning based on each sample respectively, generating a large number of pseudo-samples; Erlangshen-Roberta-330M-Causal-Chinese scored the causality of the pseudo-samples and selected the training data for itself and the generative models in the next iteration.
