Overview of this book

Deep learning is rapidly becoming the most preferred way of solving data problems. This is thanks, in part, to its huge variety of mathematical algorithms and their ability to find patterns that are otherwise invisible to us. Deep Learning from the Basics begins with a fast-paced introduction to deep learning with Python, its definition, characteristics, and applications. You’ll learn how to use the Python interpreter and the script files in your applications, and utilize NumPy and Matplotlib in your deep learning models. As you progress through the book, you’ll discover backpropagation—an efficient way to calculate the gradients of weight parameters—and study multilayer perceptrons and their limitations, before, finally, implementing a three-layer neural network and calculating multidimensional arrays. By the end of the book, you’ll have the knowledge to apply the relevant technologies in deep learning.

The Future of Deep Learning

Deep learning is now being used in various fields, as well as in the traditional fields. This section describes the possibilities of deep learning and some research that shows the future of deep learning.

Converting Image Styles

There is research being conducted that uses deep learning to "draw" a picture as an artist would. One popular use case of neural networks is to create a new image based on two provided images. One of them is called a "content image," while the other is called a "style image." A new image is created based on these two images.

In one example, you can specify Van Gogh's painting style as the style that will be applied to the content image, deep learning draws a new picture, as specified. This research was published in the paper "A Neural Algorithm of Artistic Style" (Leon A. Gatys, Alexander S. Ecker, and Matthias Bethge (2015): A Neural Algorithm of Artistic Style. arXiv:1508.06576...
