Hybrid Modeling
A technical direction that combines data-driven machine learning models with traditional numerical models based on physical equations. Physical models provide constraints from the fundamental laws of atmospheric motion, while machine learning uncovers implicit statistical regularities in historical data, offering greater robustness at time scales such as medium-range forecasting where physical constraints are critical.
Timeline (last 90 days)
Microsoft adopts a hybrid modeling strategy combining machine learning with physical simulation, using historical weather data to train models to identify hidden patterns that physical models tend to overlook.
Compared with pure AI models, hybrid modeling has more controllable dependence on training data and makes it easier to incorporate domain knowledge, and is considered a more robust path at the time scale of medium-range forecasting.
Landing point prediction in table tennis robots typically relies on a combination of physics-based models and data-driven models, where the physics-based model performs numerical integration based on air resistance, gravity, and Magnus force, while the data-driven model compensates for factors that are difficult to model.
The combination of physics-based models and data-driven models is referred to in robotics as 'hybrid modeling' or 'residual learning,' with the typical approach being that the physics model provides a baseline prediction while a neural network learns the residual error.
