**Computer vision** is one of the most important concepts in machine learning and artificial intelligence. With the wide use of smart phones for capturing, sharing, and uploading images every day, the amount of data generated through images is increasing exponentially. So, the need for experts specializing in the field of computer vision is at an all-time high. Industries such as the health care industry are on the verge of a revolution due to the progress made in the field of medical imaging. This chapter introduces you to computer vision and the various industries in which computer vision is used. You will also learn about **Convolutional Neural Networks** (**CNNs**), which are the most widely used neural networks for image processing. Like neural networks, CNNs are also made up of neurons. The neurons receive inputs that are processed using weighted sums and activation functions. However, unlike ANNs, which use vectors as inputs, a CNN uses images as its input. In this chapter, we will...

#### Overview of this book

Though designing neural networks is a sought-after skill, it is not easy to master. With Keras, you can apply complex machine learning algorithms with minimum code.
Applied Deep Learning with Keras starts by taking you through the basics of machine learning and Python all the way to gaining an in-depth understanding of applying Keras to develop efficient deep learning solutions. To help you grasp the difference between machine and deep learning, the book guides you on how to build a logistic regression model, first with scikit-learn and then with Keras. You will delve into Keras and its many models by creating prediction models for various real-world scenarios, such as disease prediction and customer churning. You’ll gain knowledge on how to evaluate, optimize, and improve your models to achieve maximum information. Next, you’ll learn to evaluate your model by cross-validating it using Keras Wrapper and scikit-learn. Following this, you’ll proceed to understand how to apply L1, L2, and dropout regularization techniques to improve the accuracy of your model. To help maintain accuracy, you’ll get to grips with applying techniques including null accuracy, precision, and AUC-ROC score techniques for fine tuning your model.
By the end of this book, you will have the skills you need to use Keras when building high-level deep neural networks.
