What Is a Machine Learning Model?

When you shop for a car, the first question is what model -- a Honda Civic for low-cost commuting, a Chevy Corvette for looking good and moving fast, or maybe a Ford F-150 to tote heavy loads. For the journey to AI, the most transformational technology of our time, the engine you need is a machine learning model. A machine learning model is an expression of an algorithm that combs through mountains of data to find patterns or make predictions. Fueled by data, ML models are the mathematical engines of AI. For example, an ML model for computer vision might be able to identify cars and pedestrians in a real-time video.
