分类任务，关于验证集问题

[howardgriffin]

在训练分类任务时，如图，我想请教下1处的数据集是哪部分数据，2处的数据集又是哪部分，为什么差别这么大，以哪个为准？

1 is train accuracy (current batch)
2 is val set accuracy @howardgriffin

1 is train accuracy (current batch) 2 is val set accuracy @howardgriffin

Thank you for your reply!
But I am confused that why the training accuracy is far lower than the validation accuracy?
