What is Dataset?

Detailed Deep Dive

A dataset is a structured collection of data points, observations, or records used to train, validate, and test machine learning models. Datasets are typically split into three subsets: a training set (used to adjust model parameters), a validation set (used to tune hyperparameters and prevent overfitting), and a test set (used to evaluate final generalization performance). The quality, diversity, and size of the dataset are critical determinants of a model's capabilities.
