The Machine Learning Workshop

2. Unsupervised Learning – Real-Life Applications

Overview

This chapter explains the concept of clustering in machine learning. It explains three of the most common clustering algorithms, with a hands-on approximation to solve a real-life data problem. By the end of this chapter, you should have a firm understanding of how to create clusters out of a dataset using the k-means, mean-shift, and DBSCAN algorithms, as well as the ability to measure the accuracy of those clusters.

Key benefits

  • Discover how to apply the scikit-learn uniform API in all types of machine learning models
  • Understand the difference between supervised and unsupervised learning models
  • Reinforce your understanding of machine learning concepts by working on real-world examples

Description

Machine learning algorithms are an integral part of almost all modern applications. To make the learning process faster and more accurate, you need a tool flexible and powerful enough to help you build machine learning algorithms quickly and easily. With The Machine Learning Workshop, you'll master the scikit-learn library and become proficient in developing clever machine learning algorithms. The Machine Learning Workshop begins by demonstrating how unsupervised and supervised learning algorithms work by analyzing a real-world dataset of wholesale customers. Once you've got to grips with the basics, you'll develop an artificial neural network using scikit-learn and then improve its performance by fine-tuning hyperparameters. Towards the end of the workshop, you'll study the dataset of a bank's marketing activities and build machine learning models that can list clients who are likely to subscribe to a term deposit. You'll also learn how to compare these models and select the optimal one. By the end of The Machine Learning Workshop, you'll not only have learned the difference between supervised and unsupervised models and their applications in the real world, but you'll also have developed the skills required to get started with programming your very own machine learning algorithms.

Who is this book for?

The Machine Learning Workshop is perfect for machine learning beginners. You will need Python programming experience, though no prior knowledge of scikit-learn and machine learning is necessary.

What you will learn

  • Understand how to select an algorithm that best fits your dataset and desired outcome
  • Explore popular real-world algorithms such as K-means, Mean-Shift, and DBSCAN
  • Discover different approaches to solve machine learning classification problems
  • Develop neural network structures using the scikit-learn package
  • Use the NN algorithm to create models for predicting future outcomes
  • Perform error analysis to improve your model s performance
  • Write unit tests to validate your code with JUnit

There are two approaches to learning ML: a theoretical approach, and a practical one. Theoretical approaches are useful if you have a background in a numerical field like mathematics or statistics. Practical approaches are useful for getting your hands dirty with the application without first trying to understand why things work. This book takes the latter approach and does an excellent job of showing you how to get things done using the very popular scikit-learn library and the Python programming language. The workshop format gives you lots of practice. You can't do ML without data, and data is rarely clean. There is an entire chapter dedicated to data preprocessing. The book teaches you how to work with various algorithms, both supervised and unsupervised. It also covers evaluation metrics. If you would like to get started with putting Machine Learning, this is a good book that I would recommend!

I enjoyed reading the book. It helps you to start in the field of Machine Learning with Python. You learn the main concepts based on the main Python library for this purpose: scikit-learn. You learn algorithms from different fields like unsupervised learning (e.g. different clustering techniques) and supervised learning (e.g. SVM, Naive Bayes, Decision Trees, Artificial Neural Networks). The algorithms are well explained.Overall it is a good book for Python developers who want to dive into the field of Machine Learning.

This is a well-written book with good breadth and depth - that covers all the key concepts and modules of ML. I love all the new examples - especially real world examples. I also like a quick introduction to NN - giving a taste of what's beyond the basic ML concepts. The best part is the demo environment where I got to play around with all the code snippets by each of the concepts.

This book is a good introduction to data analysis and the basics of machine learning. The author does a good job covering the basic algorithms (kmeans, naive bayes, svm, decision trees and even neural networks), but does not go into too much depth regarding the mathematical or statistical underpinnings. There are sample problems with straight forward code applying each of these algorithms. One thing I liked about this book was that the author sticks to well-known machine learning packages such as scikit-learn, pandas, numpy, and matplotlib, and avoids bringing in a whole lot of extraneous minor packages. This has the benefit of not requiring the user to spend a lot of time installing other dependencies, as well as building some familiarity with these packages -- which are generally powerful and popular for good reason.Overall, if you're new to the field and looking for a quick, basic introduction to some of the most well-known machine learning algorithms and techniques, this book would be a good choice.

What is custom duty/charge? Chevron down icon Chevron up icon

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
