Dataset

In machine learning, a model operates on a dataset.

Attributes of a dataset

The completeness of a dataset is the extent to which it contains all relevant features necessary for a given task.

A dataset needs to have a sufficient number of observations, measured by the size of the dataset.

The validity of the dataset is how accurate, clean, and relevant the data in the dataset is.

A dataset can be high dimensional, meaning that it has very high number of features, which can make calculations difficult.
