AI models are computer programs designed to perform specific tasks by learning from data. They analyze patterns and make predictions or decisions based on the information they have processed. Common types of AI models include neural networks, decision trees, and support vector machines, each suited for different applications like image recognition or natural language processing. These models are trained using large datasets, allowing them to improve their accuracy over time. Once trained, they can be used in various fields, such as healthcare, finance, and automotive, to automate processes, enhance decision-making, and provide insights that were previously difficult to obtain.
