Which AI technique involves training a model on a large dataset to make predictions or decisions?

The AI technique that involves training a model on a large dataset to make predictions or decisions is known as machine learning.

In machine learning, algorithms learn patterns from data through various methods, improving their performance over time without being explicitly programmed for each specific task. This technique is widely used across different applications, including natural language processing, image recognition, and recommendation systems. The process typically involves steps such as data preprocessing, feature selection, model training, and evaluation, allowing the model to generalize from past experiences to make predictions on unseen data. Machine learning is foundational in building intelligent systems that can adapt and provide insights based on large volumes of data.
