Overview of this book

Machine learning (ML) helps you find hidden insights from your data without the need for explicit programming. This book is your key to solving any kind of ML problem you might come across in your job. You’ll encounter a set of simple to complex problems while building ML models, and you'll not only resolve these problems, but you’ll also learn how to build projects based on each problem, with a practical approach and easy-to-follow examples. The book includes a wide range of applications: from analytics and NLP, to computer vision domains. Some of the applications you will be working on include stock price prediction, a recommendation engine, building a chat-bot, a facial expression recognition system, and many more. The problem examples we cover include identifying the right algorithm for your dataset and use cases, creating and labeling datasets, getting enough clean data to carry out processing, identifying outliers, overftting datasets, hyperparameter tuning, and more. Here, you'll also learn to make more timely and accurate predictions. In addition, you'll deal with more advanced use cases, such as building a gaming bot, building an extractive summarization tool for medical documents, and you'll also tackle the problems faced while building an ML model. By the end of this book, you'll be able to fine-tune your models as per your needs to deliver maximum productivity.

Understanding the concepts of face recognition


In this section, we will look at the major concepts of face recognition. These concepts will include the following topics:

  • Understanding the face recognition dataset

  • The algorithm for face recognition

Understanding the face recognition dataset

You may wonder why I haven't discussed anything related to the dataset until now. This is because I don't want to confuse you by providing all the details about the datasets of two different applications. The dataset that we will cover here is going to be used for face recognition.

If you want to build a face recognition engine from scratch, then you can use following datasets:

  • CAS-PEAL Face Dataset

  • Labeled Faces in the Wild

Let's discuss them in further detail.

CAS-PEAL Face Dataset

This is a huge dataset for face recognition tasks. It has various types of face images. It contains face images with different sources of variations, especially Pose, Emotion, Accessories, and Lighting (PEAL) for face recognition tasks...
