Keras is a minimalist, highly modular neural networks library, written in Python and capable of running on top of either TensorFlow or Theano.It was developed with a focus on enabling fast experimentation. The first step is to define the functions and classes we intend to use in this tutorial. Your stuff is quality! Fitting the model takes some time. Keras - Python Deep Learning Neural Network API. Struggled with it for two weeks with no answer from other websites experts. The training script is, What good is a serialized model unless we can deploy it? To do that, we shall install TensorFlow first, because Keras will use TensorFlow, by default, as its tensor manipulation library. It is meant only for introducing development with Keras to you. Fitting builds the compiled model with the dataset. To install TensorFlow on your machine, go to [https://www.tensorflow.org/versions/] and click on the latest stable release available. Lets not complicate any of the configurations and take things smoothly. Python has become the go-to language for Machine Learning and many of the most popular and powerful deep learning libraries and frameworks like TensorFlow, Keras, and PyTorch are built in Python. Keras gives a very useful feedback about user actions in case of any error. The main focus of Keras library is to aid fast prototyping and experimentation. You will use the Keras deep learning library to train your first neural network on a custom image dataset, and from there, you’ll implement your first Convolutional Neural Network (CNN) as well. You can add some more layers in between with different activation layers. Each video focuses on a specific concept and shows how the full implementation is done in code using Keras and Python. We shall go in deep in our subsequent tutorials, and also through many examples to get expertise in Keras. Our code examples are short (less than 300 lines of code), focused demonstrations of vertical deep learning workflows. Now, we define model using Keras Sequential() and Dense() classes. The first Dense layer consists of 10 nodes, each node receives input from eight input nodes and the activation used for the node is relu (rectified linear unit). Deep Learning with Python, Second Edition is a comprehensive introduction to the field of deep learning using Python and the powerful Keras library. The third layer is our output node and has only one node, whose activation is sigmoid, to output 1 or 0.
