In our previous tutorial, you learned how to train your first Convolutional Neural Network using the Keras library. However, you might have noticed that each time you wanted to evaluate your network or test it on a set of images,…

Now that we’ve trained our model and serialized it, we need to load it from disk. As a practical application of model serialization, I’ll be demonstrating how to classify individual images from the Animals dataset and then display the classified…

One concept we have not discussed yet is architecture visualization, the process of constructing a graph of nodes and associated connections in a network and saving the graph to disk as an image (i.e., PNG, JPG, etc.). Nodes in the…

Now that we have implemented neural networks in pure Python, let’s move on to the preferred implementation method — using a dedicated (highly optimized) neural network library such as Keras. Today, I will discuss how to implement feedforward, multi-layer networks…

In this tutorial, you will learn how to defend against adversarial image attacks using Keras and TensorFlow. So far, you have learned how to generate adversarial images using three different methods: Adversarial images and attacks with Keras and TensorFlow Targeted…

In this tutorial, you will learn about contrastive loss and how it can be used to train more accurate siamese neural networks. We will implement contrastive loss using Keras and TensorFlow. Previously, I authored a three-part series on the fundamentals…

In this tutorial, you will learn how to compare two images for similarity (and whether or not they belong to the same or different classes) using siamese networks and the Keras/TensorFlow deep learning libraries. This blog post is part three…

In this tutorial you will learn how to implement and train a siamese network using Keras, TensorFlow, and Deep Learning. This tutorial is part two in our three-part series on the fundamentals of siamese networks: Part #1: Building image pairs…

In this tutorial you will learn how to implement Generative Adversarial Networks (GANs) using Keras and TensorFlow. Generative Adversarial Networks were first introduced by Goodfellow et al. in their 2014 paper, Generative Adversarial Networks. These networks can be used to…
