Identify the primary data structure used for a machine learning algorithm
There are several data structures that can be used to store data for a machine learning algorithm, depending on the nature of data and the algorithm employed. Typically, data is stored in a tabular form, where each row represents an instance or observation and each column represents a feature or attribute. This data structure is known as a two-dimensional array or a matrix. Many machine learning libraries, including scikit-learn and TensorFlow, have built-in tools for handling data in this format. Other commonly used data structures in machine learning include lists, dictionaries, and trees.
