Machine learning is a subset of artificial intelligence that involves the use of algorithms and statistical models to enable computers to improve their performance on a task through experience. It leverages data to train models that can make predictions or decisions without being explicitly programmed for specific tasks.

Categorical data represents variables that can be divided into distinct categories, often without a natural order, and is used in statistical analysis to classify data points. Handling categorical data effectively is crucial for accurate data analysis and modeling, as it often requires encoding techniques to convert it into a numerical format for algorithms that require numerical input.

Algorithms are step-by-step procedures or formulas for solving problems or performing tasks, and are fundamental to computer science and artificial intelligence. They optimize processes by providing clear instructions that can be executed by machines to achieve desired outcomes efficiently and effectively.
