Boost your AI and generative AI accuracy using real-world datasets with over 150 functional object-oriented methods and open source libraries
Purchase of the print or Kindle book includes a free PDF eBook
Explore beautiful, customized charts and infographics in full color
Work with fully functional OO code using open source libraries in the Python Notebook for each chapter
Unleash the potential of real-world datasets with practical data augmentation techniques
Data is paramount in AI projects, especially for deep learning and generative AI, as forecasting accuracy relies on input datasets being robust. Acquiring additional data through traditional methods can be challenging, expensive, and impractical, and data augmentation offers an economical option to extend the dataset.
The book teaches you over 20 geometric, photometric, and random erasing augmentation methods using seven real-world datasets for image classification and segmentation. You’ll also review eight image augmentation open source libraries, write object-oriented programming (OOP) wrapper functions in Python Notebooks, view color image augmentation effects, analyze safe levels and biases, as well as explore fun facts and take on fun challenges. As you advance, you’ll discover over 20 character and word techniques for text augmentation using two real-world datasets and excerpts from four classic books. The chapter on advanced text augmentation uses machine learning to extend the text dataset, such as Transformer, Word2vec, BERT, GPT-2, and others. While chapters on audio and tabular data have real-world data, open source libraries, amazing custom plots, and Python Notebook, along with fun facts and challenges.
By the end of this book, you will be proficient in image, text, audio, and tabular data augmentation techniques.
