A concise guide to algorithms that will help you solve classical computer science problems using everything from fundamental algorithms like sorting and searching to modern algorithms used in machine learning and cryptography

Key Features

  • Learn the techniques you need to know to design algorithms for solving complex problems
  • Get familiar with neural network and deep learning techniques
  • Explore different types of algorithms and choose the right data structures for their optimal implementation

Book Description

Algorithms have always played an important role both in the science and practice of computing. Beyond traditional computing, the ability to use algorithms to solve real-world problems is an important skill that any developer or programmer must have. This book tries to achieve a balance between helping you develop the skill to select and use an algorithm for solving real-world problems and explaining the logic behind it.

You'll start by learning the fundamentals of algorithms and discover various algorithm design techniques, before exploring how to implement different types of algorithms such as searching, sorting, and dynamic with the help of practical examples. Next, you'll move on to a more complex set of algorithms and learn about linear programming, page ranking, and graphs. Later, you'll go through machine learning algorithms, understanding the math and logic behind them. Further on, you'll learn to use interesting case studies such as weather prediction, tweet clustering, and movie recommendation engines to apply these algorithms optimally. Finally, you'll become well-versed with techniques to enable parallel processing giving you the ability to use these algorithms for compute-intensive tasks.

By the end of this book, you will have become adept at solving real-world computational problems by using a wide range of algorithms.

What you will learn

  • Use existing data structures and algorithms found in Python libraries
  • Get to grips with fraud detection using network analysis with the help of graph algorithms
  • Use machine learning algorithms to cluster similar tweets together and process twitter data in real-time
  • Predict the weather using supervised learning algorithms
  • Use neural networks for object detection
  • Create a recommendation engine to recommend movies to subscribers
  • Use symmetric and asymmetric encryption on Google Cloud Platform(GCP)to implement fool-proof security

Who This Book Is For

This book is for anyone who wants to understand essential algorithms and their implementation. Whether you are an experienced programmer who wants to gain a deeper understanding of the math behind the algorithms, or have limited data science and programming knowledge and want to learn more about this important area of active research and application, you'll find this book useful. Although experience with Python programming is a must, knowledge of data science will be helpful but not necessary.
