Etymology

The term 'bagging' originates from the 14th century Middle English word 'bagge,' which means a sack or pouch. The word evolved as the use of bags became prominent in transporting goods. In the realm of machine learning, the term was introduced in the 1990s as a significant data analysis technique, combining the concepts of bootstrap sampling and aggregation. Its purpose was to create more robust statistical models by reducing prediction variance through the technique of averaging results from multiple models. Bagging has since become a foundational approach in machine learning, associated with methods like Random Forests.
