Book Description

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.

What you will learn

• Write OOP Python code for image, text, audio, and tabular data
• Access over 150,000 real-world datasets from the Kaggle website
• Analyze biases and safe parameters for each augmentation method
• Visualize data using standard and exotic plots in color
• Discover 32 advanced open source augmentation libraries
• Explore machine learning models, such as BERT and Transformer
• Meet Pluto, an imaginary digital coding companion
• Extend your learning with fun facts and fun challenges
