Predictive modeling

Definition

Predictive modeling is a statistical technique used to forecast outcomes based on historical data and patterns. This approach involves creating a model that can analyze past behavior, identify trends, and make predictions about future events, which is crucial in the contexts of understanding obstacles, anticipating behaviors, and avoiding collisions in autonomous vehicles.
