Building an Image Hashing Search Engine with VP-Trees and OpenCV星耀娱乐网址在线安卓

In this tutorial, you will learn how to build a scalable image hashing search engine using OpenCV, Python, and VP-Trees. Image hashing algorithms are used to: Uniquely quantify the contents of an image using only a single integer. Find duplicate or near-duplicate images in a dataset of images based on their computed hashes. Back in […]

Cyclical Learning Rates with Keras and Deep Learning星耀娱乐网址软件在线

In this tutorial, you will learn how to use Cyclical Learning Rates (CLR) and Keras to train your own neural networks. Using Cyclical Learning Rates you can dramatically reduce the number of experiments required to tune and find an optimal learning rate for your model. Today is part two in our three-part series on tuning […]

Keras learning rate schedules and decay星耀娱乐网址软件软件

In this tutorial, you will learn about learning rate schedules and decay using Keras. You’ll learn how to use Keras’ standard learning rate decay along with step-based, linear, and polynomial learning rate schedules. When training a neural network, the learning rate is often the most important hyperparameter for you to tune: Too small a learning […]

Keras ImageDataGenerator and Data Augmentation星耀娱乐网址地址客户端

In today’s tutorial, you will learn how to use Keras’ ImageDataGenerator class to perform data augmentation. I’ll also dispel common confusions surrounding what data augmentation is, why we use data augmentation, and what it does/does not do. Knowing that I was going to write a tutorial on data augmentation, two weekends ago I decided to […]

Change input shape dimensions for fine-tuning with Keras星耀娱乐网址信誉

In this tutorial, you will learn how to change the input shape tensor dimensions for fine-tuning using Keras. After going through this guide you’ll understand how to apply transfer learning to images with different image dimensions than what the CNN was originally trained on. A few weeks ago I published a tutorial on transfer learning […]
