Python Deep Learning Projects

By: Matthew Lamons, Rahul Kumar, Abhishek Nagaraja

Overview of this book

Deep learning has been gradually revolutionizing every field of artificial intelligence, making application development easier. Python Deep Learning Projects imparts all the knowledge needed to implement complex deep learning projects in the field of computational linguistics and computer vision. Each of these projects is unique, helping you progressively master the subject. You’ll learn how to implement a text classifier system using a recurrent neural network (RNN) model and optimize it to understand the shortcomings you might experience while implementing a simple deep learning system. Similarly, you’ll discover how to develop various projects, including word vector representation, open domain question answering, and building chatbots using seq-to-seq models and language modeling. In addition to this, you’ll cover advanced concepts, such as regularization, gradient clipping, gradient normalization, and bidirectional RNNs, through a series of engaging projects. By the end of this book, you will have gained knowledge to develop your own deep learning systems in a straightforward way and in an efficient way

Building the pipeline

Facial recognition is a biometric solution that measures the unique characteristics of faces. To perform facial recognition, you'll need a way to uniquely represent a face.

The main idea behind any face recognition system is to break the face down into unique features, and then use those features to represent identity.

Building a robust pipeline for feature extraction is very important, as it will directly affect the performance and accuracy of our system. In 1960, Woodrow Bledsoe used a technique involving marking the coordinates of prominent features of a face. Among these features were the location of hairline, eyes, and nose.

L
ater, in 2005, a much robust technique was invented, Histogram of Oriented Gradients (HOG). This captured the orientation of the dense pixels in the provided image.

The most advanced technique yet, outperforming all others...
