The VGG16 has 16 layers in its architecture while the VGG19 has 19 layers. ResNet50 ResNet is the short name for Residual Networks and ResNet50 is a variant of this having 50 layers Note: each Keras Application expects a specific kind of input preprocessing. For VGG19, call tf.keras.applications.vgg19.preprocess_input on your inputs before passing them to the model. vgg19.preprocess_input will convert the input images from RGB to BGR, then will zero-center each color channel with respect to the ImageNet dataset, without scaling Due to its depth and number of fully-connected nodes, VGG is over 533MB for VGG16 and 574MB for VGG19. This makes deploying VGG a tiresome task. We still use VGG in many deep learning image classification problems; however, smaller network architectures are often more desirable (such as SqueezeNet, GoogLeNet, etc.)
But VGG16 and VGG19 are famous. The main concept is stacking of convolutional layers to create deep neural networks as you can see from the table below. Here are the configurations they proposed . VGG19 model is a series of convolutional layers followed by one or a few dense (or fully connected) layers. Include_top lets you select if you want the final dense layers or not. False indicates that the final dense layers are excluded when loading the model. From the input layer to the last max pooling layer (labeled by 7 x 7 x 512) is regarded a The VGG architecture consists of blocks, where each block is composed of 2D Convolution and Max Pooling layers. VGGNet comes in two flavors, VGG16 and VGG19, where 16 and 19 are the number of layers in each of them respectively. Fig. 1 VGGNet architecture VGG16 is used in many deep learning image classification problems; however, smaller network architectures are often more desirable (such as SqueezeNet, GoogleNet, etc.) Popular deep learning frameworks like PyTorch and TensorFlow have the basic implementation of the VGG16 architecture. Below are a few relevant links. PyTorch VGG Implementatio

It is better to compare ResNet50/ResNet101 with VGG19 or ResNet18 with VGG11 because otherwise your comparison makes no sense. Based on your accuracy, deep networks work better for this dataset. A good choice would be EfficientNetB7 or DenseNet161 VGG16 and VGG19 models for Keras. application_vgg16 ( include_top = TRUE , weights = imagenet , input_tensor = NULL , input_shape = NULL , pooling = NULL , classes = 1000 ) application_vgg19 ( include_top = TRUE , weights = imagenet , input_tensor = NULL , input_shape = NULL , pooling = NULL , classes = 1000 The 13 convolutional layers of VGG16 are assembled within 5 convolution blocks each ending with a max pooling operation. Within each block the convolutional layers are responsible for pattern recognition by learning appropriate 3x3 filters, whereas max pooling reduces the images' resolution so that the network can learn large-distance features. It does so by replacing blocks of pixels by a single one corresponding to the largest value in the block, hence the name max pooling.

So the VGG16 and VGG19 models were trained in Caffe and ported to TensorFlow, hence mode == 'caffe' here (range from 0 to 255 and then extract the mean [103.939, 116.779, 123.68]). Newer networks, like MobileNet and ShuffleNet were trained on TensorFlow, so mode is 'tf' for them and the inputs are zero-centered in the range from -1 to 1. Share. Improve this answer.
