Hands-On Java Deep Learning for Computer Vision

By: Klevis Ramo

Overview of this book

Although machine learning is an exciting world to explore, you may feel confused by all of its theoretical aspects. As a Java developer, you will be used to telling the computer exactly what to do, instead of being shown how data is generated; this causes many developers to struggle to adapt to machine learning. The goal of this book is to walk you through the process of efficiently training machine learning and deep learning models for Computer Vision using the most up-to-date techniques. The book is designed to familiarize you with neural networks, enabling you to train them efficiently, customize existing state-of-the-art architectures, build real-world Java applications, and get great results in a short space of time. You will build real-world Computer Vision applications, ranging from a simple Java handwritten digit recognition model to real-time Java autonomous car driving systems and face recognition models. By the end of this book, you will have mastered the best practices and modern techniques needed to build advanced Computer Vision Java applications and achieve production-grade accuracy.

Creating Art with Neural Style Transfer

In this chapter, we will be exploring the convolution neural network internals by visualizing what these layers are trying to learn. Then, we will look at the neural style transfer problem, and how to solve that problem by using the knowledge about the layers learning process. We will then continue with a content cost function intuition, together with a bit more formal mathematical definition of the cost and derivation. We will go through the details of building the style cost function, which are slightly more complex, and how to efficiently capture the style of an image in terms of convolution layers. Finally, we will present the optimized architecture, together with the core details for the Java implementation for neural style transfer. We will also show an image sample for a few iterations.

We will be covering the following topics:
