VGG有两种结构，分别是 VGG16 和 VGG19，两者并没有本质上的区别，只是网络深度不一样。 VGG原理. VGG16相比AlexNet的一个改进是 采用连续的几个3x3的卷积核代替AlexNet中的较大卷积核（11x11，7x7，5x5）。 对于给定的感受野（与输出有关的输入图片的局部大小），采用堆积的小卷积核是优于采用大的卷积核，因为多层非线性层可以增加网络深度来保证学习更复杂的模式，而且代价还比较小（参数更少）。 简单来说，在VGG中，使用了3个3x3卷积核来代替7x7 …

2024年6月7日 · VGG-19 is a deep convolutional neural network with 19 weight layers, comprising 16 convolutional layers and 3 fully connected layers. The architecture follows a straightforward and repetitive pattern, making it easier to understand and implement. The key components of the VGG-19 architecture are:

2020年4月2日 · VGG 全称是 Visual Geometry Group，因为是由 Oxford 的 Visual Geometry Group 提出的。 AlexNet 问世之后，很多学者通过改进 AlexNet 的网络结构来提高自己的准确率，主要有两个方向：小卷积核和多尺度。 而 VGG 的作者们则选择了另外一个方向，即加深网络深度。 卷积网络的输入是 224 * 224 的 RGB 图像，整个网络的组成是非常格式化的，基本上都用的是 3 * 3 的卷积核以及 2 * 2 的 max pooling，少部分网络加入了 1 * 1 的卷积核。 因为想要体 …

VGG is a classical convolutional neural network architecture. It was based on an analysis of how to increase the depth of such networks. The network utilises small 3 x 3 filters. Otherwise the network is characterized by its simplicity: the only other components being pooling layers and a fully connected layer. Image: Davi Frossard.

2024年3月12日 · VGG16 is a deep convolutional neural network model used for image classification tasks. The network is composed of 16 layers of artificial neurons, which each work to process image information incrementally and improve the accuracy of its predictions.
