ResNet在2015年被提出，在ImageNet比赛classification任务上获得第一名，因为它“简单与实用”并存，之后很多方法都建立在ResNet50或者ResNet101的基础上完成的，检测，分割，识别等领域都纷纷使用ResNet，Alpha zero也使用了ResNet，所以可见ResNet确实很好用。(ResNet was proposed in 2015 and won the first place in the classification task of ImageNet competition. Since it was "simple and practical", many methods were built on ResNet50 or ResNet101. ResNet was used in detection, segmentation, recognition and other fields.)
