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...
Our goal will be to implement a Keras generator capable of training a network on this CSV image data(don’t worry, I’ll show you how to implement such a generator function from scratch). Finally, we’ll train and evaluate our network. When to use Keras’ fit, fit_generator, and tra...
Learn how to use Keras models to make predictions and detect trends. Before we start:This Python tutorial is a part ofour series of Python Package tutorials. Keras models can be used to detect trends and make predictions, using themodel.predict()class and it’s variant,reconstructed_model.p...
In this tutorial, you will discover how to use the built-in metrics and how to define and use your own metrics when training deep learning models in Keras. After completing this tutorial, you will know: How Keras metrics work and how you can use them when training your models. How to ...
How to Use Keras model? As the Keras model is a python-based library, it must be used for flexibility and customized model design, especially for prediction. Keras model has its way of detecting trends with behavior for modeling and prediction. ...
The Keras Python library makes creating deep learning models fast and easy. The sequential API allows you to create models layer-by-layer for most problems. It is limited in that it does not allow you to create models that share layers or have multiple inputs or outputs. The functional API...
In this quick tutorial, I am going to show you two simple examples to use the sparse_categorical_crossentropy loss function and the sparse_categorical_accuracy metric when compiling your Keras model.Example one - MNIST classificationAs one of the multi-class, single-label classification datasets, ...
