Datasets are collections of data that are used for various purposes in fields like machine learning, data analysis, and research. They can be categorized based on their application, such as vision, natural language processing (NLP), healthcare, and more. Public datasets are often available for free and can be accessed from various sources, including government databases and academic institutions.

For example, the U.S. Department of Agriculture provides datasets related to agriculture, such as the PLANTS Database and the Nutrient Database. In the realm of machine learning, popular datasets include the Boston Housing dataset, which is used for regression tasks, and the Breast Cancer dataset, which is used for classification tasks. These datasets often contain structured data with specific features that can be analyzed to derive insights or build predictive models ¹²³.
