Description

As machine learning practitioners, we often encounter imbalanced datasets in which one class has considerably fewer instances than the other. Many machine learning algorithms assume an equilibrium between majority and minority classes, leading to suboptimal performance on imbalanced data. This comprehensive guide helps you address this class imbalance to significantly improve model performance. Machine Learning for Imbalanced Data begins by introducing you to the challenges posed by imbalanced datasets and the importance of addressing these issues. It then guides you through techniques that enhance the performance of classical machine learning models when using imbalanced data, including various sampling and cost-sensitive learning methods. As you progress, you’ll delve into similar and more advanced techniques for deep learning models, employing PyTorch as the primary framework. Throughout the book, hands-on examples will provide working and reproducible code that’ll demonstrate the practical implementation of each technique. By the end of this book, you’ll be adept at identifying and addressing class imbalances and confidently applying various techniques, including sampling, cost-sensitive techniques, and threshold adjustment, while using traditional machine learning or deep learning models.

Who is this book for?

This book is for machine learning practitioners who want to effectively address the challenges of imbalanced datasets in their projects. Data scientists, machine learning engineers/scientists, research scientists/engineers, and data scientists/engineers will find this book helpful. Though complete beginners are welcome to read this book, some familiarity with core machine learning concepts will help readers maximize the benefits and insights gained from this comprehensive resource.

What you will learn

  • Use imbalanced data in your machine learning models effectively
  • Explore the metrics used when classes are imbalanced
  • Understand how and when to apply various sampling methods such as over-sampling and under-sampling
  • Apply data-based, algorithm-based, and hybrid approaches to deal with class imbalance
  • Combine and choose from various options for data balancing while avoiding common pitfalls
  • Understand the concepts of model calibration and threshold adjustment in the context of dealing with imbalanced datasets

This book on tackling real imbalanced datasets in machine learning is a detailed and comprehensive guide. The chapters ‘cost-sensitive learning’ and ‘model calibration’ require special mention, which were blended in well with other chapters on over-sampling, under-sampling and ensemble techniques for handling data imbalance. While some essential concepts have in-depth explanations and rightfully so, the authors have managed well to keep the book intriguing all along which makes it a prized resource for all machine learning practitioners.

The book covers various methods to address the class imbalance problem, and covers usage with popular python libraries and typical evaluation metrics from the lens of class imbalance.Here're some of my top takeaways from the book:🎲 Sampling methods, such as over-sampling, under-sampling, and hybrid sampling, to balance the data distribution📊 Cost-sensitive learning, which assigns different weights or costs to different classes, to make the model more sensitive to the minority class📈 Threshold adjustment, which modifies the decision threshold of the model, to improve the performance metrics🗂 Model calibration, which adjusts the predicted probabilities of the model, to make them more reliable and interpretable🚀 My favorite part of the book: How several big tech companies are solving data imbalance challenges in different contexts🗃 There's a python library `imbalanced-learn` that offers out-of-the-box techniques to deal with data imbalance and can also be used to create corresponding synthetic datasetsHaving read several books from Packt, it's so interesting to go through these books as they deal with very specific subtopics within ML and provide an entire landscape of practical techniques, real-world use-cases, and top takeaways for practitioners based on research findings.

This book provided a great overview in a concise and clear format of dealing with imbalanced datasets and what techniques to use. The text contains helpful examples and insights from the author's industry experience. I enjoyed the cartoon strips added in chapters for easy understanding. The collab notebooks provided in the GitHub repo provide the coding practice needed to utilize the theory in the book. I would recommend this to anyone learning more about machine learning as most of the datasets in real life are imbalanced.

If you have any feedback about the product you're reading, or Early Access in general, then please fill out a contact form here and we'll make sure the feedback gets to the right team. 

Can I download the code files for Early Access titles? Chevron down icon Chevron up icon

We try to ensure that all books in Early Access have code available to use, download, and fork on GitHub. This helps us be more agile in the development of the book, and helps keep the often changing code base of new versions and new technologies as up to date as possible. Unfortunately, however, there will be rare cases when it is not possible for us to have downloadable code samples available until publication.

When we publish the book, the code files will also be available to download from the Packt website.

How accurate is the publication date? Chevron down icon Chevron up icon

The publication date is as accurate as we can be at any point in the project. Unfortunately, delays can happen. Often those delays are out of our control, such as changes to the technology code base or delays in the tech release. We do our best to give you an accurate estimate of the publication date at any given time, and as more chapters are delivered, the more accurate the delivery date will become.

How will I know when new chapters are ready? Chevron down icon Chevron up icon

We'll let you know every time there has been an update to a course that you've bought in Early Access. You'll get an email to let you know there has been a new chapter, or a change to a previous chapter. The new chapters are automatically added to your account, so you can also check back there any time you're ready and download or read them online.

Keeping up to date with the latest technology is difficult; new versions, new frameworks, new techniques. This feature gives you a head-start to our content, as it's being created. With Early Access you'll receive each chapter as it's written, and get regular updates throughout the product's development, as well as the final course as soon as it's ready.We created Early Access as a means of giving you the information you need, as soon as it's available. As we go through the process of developing a course, 99% of it can be ready but we can't publish until that last 1% falls in to place. Early Access helps to unlock the potential of our content early, to help you start your learning when you need it most. You not only get access to every chapter as it's delivered, edited, and updated, but you'll also get the finalized, DRM-free product to download in any format you want when it's published. As a member of Packt, you'll also be eligible for our exclusive offers, including a free course every day, and discounts on new and popular titles.
