Reference:

• Very Deep Convolutional Networks for Large-Scale Image Recognition (ICLR 2015) This class represents Keras Backbone of VGG16 model. Arguments

• include_rescaling: bool, whether to rescale the inputs. If set to True, inputs will be passed through a Rescaling(1/255.0) layer.
• include_top: bool, whether to include the 3 fully-connected layers at the top of the network. If provided, num_classes must be provided.
• num_classes: int, optional number of classes to classify images into, only to be specified if include_top is True.
• input_shape: tuple, optional shape tuple, defaults to (224, 224, 3).
• input_tensor: Tensor, optional Keras tensor (i.e. output of layers.Input()) to use as image input for the model.
• pooling: bool, Optional pooling mode for feature extraction when include_top is False.
  • None means that the output of the model will be the 4D tensor output of the last convolutional block.
  • avg means that global average pooling will be applied to the output of the last convolutional block, and thus the output of the model will be a 2D tensor.
  • max means that global max pooling will be applied.
• classifier_activation:str or callable. The activation function to use on the “top” layer. Ignored unless include_top=True. Set classifier_activation=None to return the logits of the “top” layer. When loading pretrained weights, classifier_activation can only be None or "softmax".
• name: (Optional) name to pass to the model, defaults to “VGG16”.

Returns

A keras.Model instance.
