训练过程中没有进行验证集的评估:val_loss和val_accuracy是用于评估模型在验证集上的损失和准确率。如果在训练过程中没有设置验证集或者没有进行验证集的评估,那么就不会显示这些指标。 代码中没有正确设置验证集的评估:在训练模型时,需要在代码中明确指定验证集,并在每个纪元结束后计算验证集上的损失和准确率。...

type:"Accuracy" bottom:"ip2" bottom:"label" top:"accuracy" include { phase: TEST } } 最后还有一个不同就是,因为是训练模型,所以包括forward和backward,所以最后需要定义一个损失函数。这里用的是SoftmaxWithLoss,而在deploy.prototxt,因为只有forward,所以定义的是Softmax,也就是分类器。
