Machine learning algorithms

Definition

Machine learning algorithms are computational methods that enable systems to learn from data and improve their performance over time without being explicitly programmed. These algorithms analyze patterns in data and make predictions or decisions based on the insights they derive, making them particularly valuable in tasks like pigment and material analysis where complex datasets are common.
