译者注:本篇翻译自Alex Krizhevsky, Ilya Sutskever以及Geoffrey E.Hinton的论文 ImageNet Classification with Deep Convolutional Neural Networks. 该论文在智能单元专栏文章《CS231n课程笔记翻译:神经网络笔记1(上)》中有提到,因此打算翻译一下,一来强化自己的理解,二来供读者参考。文中涉及的名词翻译主要是参考智能...
In the network, we apply pooling with a filter of 2 by 2 and apply a Dropout layer to prevent overfitting. The final layer has 101 units because there are 101 food classes. The activation function is softmax because it is a multiclass image classification problem. Compiling the CNN model ...
这篇论文的全名是:Bag of Tricks for Image Classification with Convolutional Neural Networks 。论文地址见附录。这篇论文是亚马逊团队对CNN网络调优的经验总结,实验基本是在分类网络实验上做的。目前,论文的复现结果都可以在GluonCV找到,地址为:...

打开使用CNN网络进行图像分类之路的就是这个Alexnet网络(论文原文在此:http://papers.nips.cc/paper/4824-imagenet-classification-with-deep-convolutional-neural-networks.pdf,有兴趣的读者可以自己查阅,虽然到现在我还是没有把这篇论文完整的细细研读完毕),自此网络之后,其他像VGGNet、GoogleNet、ResNet等如雨后春笋般...
图像分类(Image Classification)是对图像内容进行分类的问题,它利用计算机对图像进行定量分析,把图像或图像中的区域划分为若干个类别,以代替人的视觉判断。图像分类的传统方法是特征描述及检测,这类传统方法可能对于一些简单的图像分类是有效的,但由于实际情况非常复杂,传统的分类方法不堪重负。现在,广泛使用机器学习和深度...
The feature learning methods based on convolutional neural network (CNN) have successfully produced tremendous achievements in image classification tasks. However, the inherent noise and some other factors may weaken the effectiveness of the convolutional feature statistics. In this paper, we investigate ...
● 1*1 conv(最初提出的并非GoogLeNet,而是Network In Network这篇论文)的使用有效地减少了conv的深度,减少模型参数; ● 模型增加softmax0和softmax1,在训练的时候,将三个分类器的损失函数进行加权求和,以缓解梯度消失现象。 4.4 应用场景 ● 主要用于Image Classification,其中Inception模块可以作为CNN主干网络的基本...
