In this blog, we will classify image with pre-trained model ResNet50.
Keras Applications are deep learning models that are made available alongside pre-trained weights. These models can be used for prediction, feature extraction, and fine-tuning.
Weights are downloaded automatically when instantiating a model. They are stored at ~/.keras/models/.
ResNet-50 is a convolutional neural network that is 50 layers deep(48 Convolution layers along with 1 MaxPool and 1 Average Pool layer). A residual neural network (ResNet) is an artificial neural network (ANN) of a kind that stacks residual blocks on top of each other to form a network.
We can load a pretrained version of the network trained on more than a million images from the ImageNet database. The pretrained network can classify images into 1000 object categories, such as keyboard, mouse, pencil, and many animals. The network has an image input size of 224-by-224.

tf.keras.applications.resnet50.ResNet50( include_top=True, weights='imagenet', input_tensor=None, input_shape=None, pooling=None, classes=1000, **kwargs ) Instantiates the ResNet50 architecture.
Args include_top: whether to include the fully-connected layer 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 (224, 224, 3) (with 'channels_last' data format) or (3, 224, 224) (with 'channels_first' data format). It should have exactly 3 inputs channels, and width and height should be no smaller than 32. E.g. (200, 200, 3) would be one valid value.
pooling: Optional pooling mode for feature extraction when include_top is False.
1. None means that the output of the model will be the 4D tensor output of the last convolutional block.
2. 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.
3. 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.
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".
Returns A Keras model instance.
