Python Algorithms, Second Edition explains the Python approach to algorithm analysis and design.

Python Algorithms, Second Edition explains the Python approach to algorithm analysis and design. Written by Magnus Lie Hetland, author of Beginning Python, this book is sharply focused on classical algorithms, but it also gives a solid understanding of fundamental algorithmic problem-solving techniques. The book deals with some of the most important and challenging areas of programming and computer science in a highly readable manner. It covers both algorithmic theory and programming practice, demonstrating how theory is reflected in real Python programs. Well-known algorithms and data structures that are built into the Python language are explained, and the user is shown how to implement and evaluate others.What youll learnHow to transform new problems to well-known algorithmic problems with efficient solutions, or show that the problems belong to classes of problems thought not to be efficiently solvableHow to analyze algorithms and Python programs using both mathematical tools and basic experiments and benchmarksHow to understand several classical algorithms and data structures in depth, and be able to implement these efficiently in PythonHow to design and implement new algorithms for new problems, using time-tested design principles and techniquesHow to speed up implementations, using a plethora of tools for high-performance computing in PythonWho this book is for The book is intended for Python programmers who need to learn about algorithmic problem-solving, or who need a refresher. Data and computational scientists employed to do big data analytic analysis should find this book useful. Game programmers and financial analysts/engineers may find this book applicable too. And, students of computer science, or similar programming-related topics, such as bioinformatics, may also find the book to be quite useful. Table of Contents1. Introduction2. The Basics3.

Learn Kotlin the easy way while developing an Android App

In this book, I’ll be creating an Android app from ground up using Kotlin as the main language. The idea is to learn the language by example, instead of following a regular reference book structure. I’ll be stopping to explain the most interesting concepts and ideas about Kotlin, comparing them to Java 6. This way, you can see what the differences are and which parts of the language will help you speed up your work. This book is not meant to be a language reference, but a tool for Android developers to learn Kotlin and be able to continue with their own projects by themselves. I’ll be solving many of the most recurring problems we have to face in our daily lives as App developers, by making use of Kotlin expressiveness and some other really interesting tools and libraries. However, this text covers most Kotlin features, so by the end of the reading you will have a deep knowledge about the language. The content is very practical, so I recommend you to follow the examples and the code in front of a computer and try everything it’s suggested. You could, however, take a first read to get a broad idea and then dive into practice. Even though this book now finished, I will review it from time to time to keep it up to date with new Kotlin versions. So feel free to write and tell me what you think about the book, or what could be improved. I want this book to be the perfect tool for Android developers, and as such, help and ideas will be welcomed. If you are reading a printed copy and want to receive the latest updates, please feel free to write me back to contact@antonioleiva.com with a proof of purchase, and I’ll give you access to the digital copy. That way, you’ll keep receiving the updates. Thanks for becoming part of this exciting project!

A Simplified Approach to Developing Database-Driven Websites

The code and instructions in the first edition of this book (written in 2012) were made obsolete by new and very different versions of XAMPP, EasyPHP, phpMyAdmin, PHP, and MySQL/MariaDB. This second edition contains new code and instructions to match the latest versions of the software.With the massive increase in cybercrime and other cyber threats, this new edition has been fortified with a much stronger emphasis on security. This book takes the approach of sanitizing any data that has been accepted from any outside source and, additionally, sanitizing any data before it is displayed on a web page. Most of the examples use prepared statements that ensure that any externally accepted data cannot be executed and therefore cannot cause security vulnerabilities.We have chosen Bootstrap to provide responsive web design (RWD) for each of the book’s example websites. While Bootstrap provides the CSS and JavaScript to format the examples in this book for any size device, you can easily reformat these examples with your own CSS code if you desire.This new edition also takes a brief look at Oracle’s MySQL 8. A comparison is provided of the tools available in each version. Step-by-step procedures provide you with the ability to upgrade to MySQL 8.

IA

Artificial Intelligence (AI) is a big field, and this is a big book. We have tried to explore the full breadth of the field, which encompasses logic, probability, and continuous mathematics; perception, reasoning, learning, and action; and everything from microelectronic devices to robotic planetary explorers. The book is also big because we go into some depth. The subtitle of this book is “A Modern Approach.” The intended meaning of this rather empty phrase is that we have tried to synthesize what is now known into a common framework, rather than trying to explain each subfield of AI in its own historical context. We apologize to those whose subfields are, as a result, less recognizable

IA

Acerca de este libro Este libro se desarrolló conforme enseñaba MATLAB y otros lenguajes de computación a es-tudiantes nuevos de ingeniería en la Salt Lake community College. Me sentía frustrada por la falta de un texto que "comenzara desde el principio”. Aunque había muchos libros de referencia muy abarcadores, todos suponían un nivel elevado de matemáticas y conocimientos de computación que mis estudiantes no tenían. Además, debido a que MATLAB fue adoptado en sus orígenes por profesionales de los campos de procesamiento de señales e ingeniería eléctrica, la mayoría de dichos textos daban ejemplos principalmente de dichas áreas, enfoque que no se adaptaba a un currículo general de ingeniería. Este texto comienza con álgebra básica y muestra cómo se puede usar MATLAB para resolver problemas de ingeniería de un rango amplio de disciplinas. Los ejemplos proceden de conceptos que se introducen en las primeras clases de química y física, y de las clases de ingeniería de los primeros semestres. Se utiliza de manera consistente una metodología estándar para resolver problemas.

Discover a variety of data-mining algorithms that are useful for selecting small sets of important features from among unwieldy masses of candidates, or extracting useful features from measured variables.

As a serious data miner you will often be faced with thousands of candidate features for your prediction or classification application, with most of the features being of little or no value. You’ll know that many of these features may be useful only in combination with certain other features while being practically worthless alone or in combination with most others. Some features may have enormous predictive power, but only within a small, specialized area of the feature space. The problems that plague modern data miners are endless. This book helps you solve this problem by presenting modern feature selection techniques and the code to implement them.
