The term supervised refers to an action or process that is overseen by a responsible authority figure. In other words, it means being monitored and guided by someone who has knowledge and experience in a particular field or task. This person ensures that everything is done correctly and provides guidance when needed.
In the context of machine learning, supervised refers to a type of learning where an algorithm is trained on labeled data - meaning that the input data is already classified with correct answers. The algorithm learns by comparing its predictions against the known outcomes in order to improve its accuracy over time. This process continues until the desired level of performance is achieved, at which point the model can be used for prediction or decision-making tasks.
Overall, supervised means being guided and directed towards a specific goal with the help of an experienced individual who provides guidance and support along the way.
