Datasets consist of data organized in a structured or semi-structured way, commonly employed for analysis, research, and applications in fields such as machine learning, statistics, and data science. Imagine a dataset as a table where each row stands for an individual item or observation, and each column represents a distinct attribute or feature of that item.
Datasets are fundamental to data science, acting as the foundational elements for analysis, research, and applications across various fields like machine learning, statistics, and data science. Think of datasets as tables, where each row holds information about an item or observation, and columns represent different attributes or features.
Datasets play a vital role in training machine learning models, validating hypotheses in scientific research, making business decisions grounded in historical patterns, and more. They serve as the foundational material from which algorithms learn and generate predictions or glean insights.
