Hugging Face Datasets Overview 📚

Welcome to the Hugging Face Datasets documentation! This guide provides essential information for working with datasets in machine learning workflows. 🌟

What Are Datasets? 📊

Datasets are structured collections of data used to train, evaluate, and test machine learning models. Hugging Face offers a wide range of datasets, including:

• Text data (e.g., Wikipedia, BookCorpus)
• Audio data (e.g., LibriSpeech, CommonVoice)
• Image data (e.g., CIFAR-10, ImageNet)
• Custom datasets (upload your own data easily)

Key Features 🚀

• Preprocessing tools: Built-in functions for tokenization, filtering, and splitting data
• Lazy loading: Efficient memory usage with on-demand data loading
• Versioning: Track changes in datasets over time
• Integration with Transformers: Seamless compatibility with Hugging Face's transformers library

How to Use Datasets? 🧪

1. Load a dataset using load_dataset()

   from datasets import load_dataset
   dataset = load_dataset("wikipedia", "20220301.en")
   

2. Explore dataset structure with .keys() and .num_rows
3. Split data into training, validation, and test sets

   train_data = dataset["train"].shuffle().select(range(1000))
   

4. Customize datasets with map() and filter() functions
