tf.keras.applications.EfficientNetB2

Instantiates the EfficientNetB2 architecture.

tf.keras.applications.EfficientNetB2(     include_top=True,     weights='imagenet',     input_tensor=None,     input_shape=None,     pooling=None,     classes=1000,     classifier_activation='softmax',     **kwargs )

Reference:

This function returns a Keras image classification model, optionally loaded with weights pre-trained on ImageNet.

For image classification use cases, see this page for detailed examples.

For transfer learning use cases, make sure to read the guide to transfer learning & fine-tuning.

include_top Whether to include the fully-connected layer at the top of the network. Defaults to True.
weights One of None (random initialization), "imagenet" (pre-training on ImageNet), or the path to the weights file to be loaded. Defaults to "imagenet".
input_tensor Optional Keras tensor (i.e. output of layers.Input()) to use as image input for the model.
input_shape Optional shape tuple, only to be specified if include_top is False. It should have exactly 3 inputs channels.
pooling Optional pooling mode for feature extraction when include_top is False. Defaults to None.
  • None means that the output of the model will be the 4D tensor output of the last convolutional layer.
  • avg means that global average pooling will be applied to the output of the last convolutional layer, and thus the output of the model will be a 2D tensor.
  • max means that global max pooling will be applied.
classes Optional number of classes to classify images into, only to be specified if include_top is True, and if no weights argument is specified. 1000 is how many ImageNet classes there are. Defaults to 1000.
classifier_activation A 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. Defaults to 'softmax'. When loading pretrained weights, classifier_activation can only be None or "softmax".
