Introduction
DataSet:
A dataset is a collection of related data points that are organized and structured for easy use and analysis. In the context of computing, a dataset may refer to any type of digital information, such as a collection of images, a set of text documents, a table of numerical values, or any other type of structured or unstructured data.
Datasets are used in a wide range of applications, including scientific research, machine learning, data mining, and business intelligence. They can be used to identify patterns, relationships, and insights within the data, and to make informed decisions or predictions based on that information.
Datasets can be collected from various sources, such as surveys, experiments, observations, or from existing databases. They can also be created by scraping data from websites or other online sources. Once collected, the data is usually cleaned, processed, and transformed into a format that is suitable for analysis.
