AI GLOSSARY

Objective Function

An objective function is a mathematical expression that a machine learning or optimisation algorithm seeks to minimise or maximise. It defines the goal of the model, such as minimising error or maximising accuracy, and serves as a guide for evaluating potential solutions. In AI, the objective function plays a critical role in training models as it determines the quality of the outcomes based on the chosen metrics.
