Model Reduction (disambiguation)

Model Reduction may refer to:

• 💡

  Model reduction (numerical methods / dynamical systems)

  Techniques for approximating a high-dimensional dynamical system with a smaller, computationally efficient model.

• 💡

  Model Reduction in control theory

  Model-order reduction methods used to obtain simpler system models for controller design and analysis.

• 💡

  Proper Orthogonal Decomposition (POD) for model reduction

  A widely used data-driven or snapshot-based method (POD) that constructs reduced-order models from dominant modes.

• 💡

  Reduced-order modeling (ROM)

  The broader practice of building reduced models to speed up simulations and analyses, often using projection-based or surrogate approaches.
