Instantiates the Xception architecture.
tf.keras.applications.Xception( include_top=True, weights='imagenet', input_tensor=None, input_shape=None, pooling=None, classes=1000, classifier_activation='softmax' )
Reference:
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.
The default input image size for this model is 299x299.
Args | |
---|---|
include_top | whether to include the 3 fully-connected layers at the top of the network. |
weights | one of None (random initialization), "imagenet" (pre-training on ImageNet), or the path to the weights file to be loaded. |
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 (otherwise the input shape has to be (299, 299, 3) . It should have exactly 3 inputs channels, and width and height should be no smaller than 71. E.g. (150, 150, 3) would be one valid value. |
pooling | Optional pooling mode for feature extraction when include_top is False .
|
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. |
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. When loading pretrained weights, classifier_activation can only be None or "softmax" . |
