Reference

• EfficientNet: Rethinking Model Scaling for Convolutional Neural Networks (ICML 2019)

This function returns a TF-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.

Note: each TF-Keras Application expects a specific kind of input preprocessing. For EfficientNet, input preprocessing is included as part of the model (as a Rescaling layer), and thus tf.keras.applications.efficientnet.preprocess_input is actually a pass-through function. EfficientNet models expect their inputs to be float tensors of pixels with values in the [0-255] range.

Arguments

• 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 TF-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".

Returns

A keras.Model instance.
