The Keras deep learning library provides a sophisticated API for loading, preparing, and augmenting image data. Also included in the API are some undocumented functions that allow you to quickly and easily load, convert, and save image files. These functions can be convenient when getting started...
Kerasis an Open Source Neural Network library written in Python that runs on top of Theano or Tensorflow. It is designed to be modular, fast and easy to use. It was developed by François Chollet, a Google engineer. Keras doesn’t handle low-level computation. Instead, it uses another l...

Make note of your API key as you’ll need it in the next section. Building a deep learning dataset with Python Now that we have registered for the Bing Image Search API, we are ready to build our deep learning dataset. Read the docs ...
For the implementation part of the autoencoder, we will use the popular MNIST dataset of digits. 1. Simple Autoencoder We begin by importing all the necessary libraries : import all the dependencies from keras.layers import Dense,Conv2D,MaxPooling2D,UpSampling2D ...
In both cases, the name of the metric function is used as the key for the metric values. In the case of metrics for the validation dataset, the “val_” prefix is added to the key. Both loss functions and explicitly defined Keras metrics can be used as training metrics. Keras ...
