text2vec-base-chinese

这有可能是基础模型的问题,可能 hfl/roberta 没有 hfl/macbert 适合你的使用场景。另外,微调的程度不同,模型的灾难性遗忘水平也不同。如果你微调的轮数比较多,那么模型的能力可能主要就取决于架构了,之前学习到的参数分布可能就不重要了(遗忘掉了)。当然,上述都是猜测,我只是根据过往的经验来推断的。

这个变量有点太多了,我没仔细研究过 text2vec 的代码... 我需要去调研一下,之后做一些实验才能解答。

数据层面上,max_length 是不是一致的?我记得 text2vec 的 max_length 好像默认不是 512

首先感谢答复!

max_length我也改成512了

此外,我还有个疑问:直接拿text2vec-base-chinese和m3e-model在我们自己的数据集上预测,m3e-model的指标明显高于text2vec-base-chinese,但是用我们的数据fintune后,m3e-model反而微弱于text2vec-base-chinese,这是为啥呀?
