This example shows how to do image classification from scratch, starting from JPEGimage files on disk, without leveraging pre-trained weights or a pre-made KerasApplication model. We demonstrate the workflow on the Kaggle Cats vs Dogs binaryclassification dataset. We use the image_dataset_from_directoryutility to generate the datasets, andwe use Ke...
Raw data download
First, let's download the 786M ZIP archive of the raw data: Now we have a PetImages folder which contain two subfolders, Cat and Dog. Eachsubfolder contains image files for each category.
Filter out corrupted images
When working with lots of real-world image data, corrupted images are a commonoccurence. Let's filter out badly-encoded images that do not feature the string "JFIF"in their header.
When you don't have a large image dataset, it's a good practice to artificiallyintroduce sample diversity by applying random yet realistic transformations to thetraining images, such as random horizontal flipping or small random rotations. Thishelps expose the model to different aspects of the training data while slowing downoverfitting. Let's visu...
Our image are already in a standard size (180x180), as they are being yielded ascontiguous float32 batches by our dataset. However, their RGB channel values are inthe [0, 255] range. This is not ideal for a neural network;in general you should seek to make your input values small. Here, we willstandardize values to be in the [0, 1] by using a Resca...
There are two ways you could be using the data_augmentationpreprocessor: Option 1: Make it part of the model, like this: With this option, your data augmentation will happen on device, synchronouslywith the rest of the model execution, meaning that it will benefit from GPUacceleration. Note that data augmentation is inactive at test time, so the in...
Let's apply data augmentation to our training dataset,and let's make sure to use buffered prefetching so we can yield data from disk withouthaving I/O becoming blocking:
We'll build a small version of the Xception network. We haven't particularly tried tooptimize the architecture; if you want to do a systematic search for the best modelconfiguration, consider usingKerasTuner. Note that: 1. We start the model with the data_augmentation preprocessor, followed by a Rescalinglayer. 2. We include a Dropoutlayer before t...
We get to >90% validation accuracy after training for 25 epochs on the full dataset(in practice, you can train for 50+ epochs before validation performance starts degrading).
