#Keras data augmentation tutorial how to

This means, variations of the training set images that are likely to be seen by the model. The intent is to expand the training dataset with new, plausible examples. Transforms include a range of operations from the field of image manipulation, such as shifts, flips, zooms, and much more. Image data augmentation is perhaps the most well-known type of data augmentation and involves creating transformed versions of images in the training dataset that belong to the same class as the original image. This is done by applying domain-specific techniques to examples from the training data that create new and different training examples. The performance of deep learning neural networks often improves with the amount of data available.Дata augmentation is a technique to artificially create new training data from existing training data. Horizontal and Vertical Flip Augmentation.Horizontal and Vertical Shift Augmentation.Image Augmentation With ImageDataGenerator.This tutorial is divided into eight parts they are:

#Keras data augmentation tutorial how to

How to use shift, flip, brightness, and zoom image data augmentation.Image data augmentation is supported in the Keras deep learning library via the ImageDataGeneratorВ class.Image data augmentation is used to expand the training dataset in order to improve the performance and ability of the model to generalize.In this tutorial, you will discover how to use image data augmentation when training deep learning neural networks.ДЄfter completing this tutorial, you will know: The Keras deep learning neural network library provides the capability to fit models using image data augmentation via the ImageDataGeneratorВ class. Training deep learning neural network models on more data can result in more skillful models, and the augmentation techniques can create variations of the images that can improve the ability of the fit models to generalize what they have learned to new images.

Image data augmentation is a technique that can be used to artificially expand the size of a training dataset by creating modified versions of images in the dataset.
