top-5 error rate:模型训练前设定了很多类别,模型训练后样本被划分到每个类别都有一定的概率,取概率最大的5个类别,即top5,只要有一个是符合样本的类别就算对,反之就算预测失败,用预测失败的样本数量比上总数就是top-5 error rate。 top-1 error rate:只取概率最大的那1个类别,即top1,其他条件同上。 ———...
通俗的讲,所谓Top-1 error-rate就是使用预测结果和正确结果进行对比,如果相同则表示预测正确! 相比而言,Top-5 error-rate 就是使用预测结果的Top-5(分类结果标签的前五个)与正确结果进行对比,如果五个之中有一个正确那么就认为分类器预测结果正确。 一般来说,Top-1和Top-5错误率越低,模型的性能也就越好。且...
正确率是我们最常见的评价指标,accuracy = (TP+TN)/(P+N),这个很容易理解,就是被分对的样本数除以所有的样本数,通常来说,正确率越高,分类器越好; 2)错误率(error rate) 错误率则与正确率相反,描述被分类器错分的比例,error rate = (FP+FN)/(P+N),对某一个实例来说,分对与分错是互斥事件,所以acc...

show that such a simple framework can achieve state-of-the-art results without involving any commonly-used tricks, such as 1) architecture modification; 2) outside training data beyond ImageNet; 3) autoaug/randaug; 4) cosine learning rate; 5) mixup/cutmix training; 6) label smoothing; etc...
the response. I wasnt expecting this question to go very far. I did end up using "AND" i/o "&" in the TOP 1 query (after [dte]: and projid=projid ) inbluebelow but it still didnt seem to work. I didnt get an error or syntax but it didnt return the correct rate for proj...
