Parametric model
A parametric model is a model with a specified structural or functional form whose behavior is determined by a finite set of parameters.
Outlier Detection in Python
A parametric model assumes a specified structural form and estimates a finite set of parameters describing that form.
- How it is used
- Supports outlier detection by estimating whether observations fit an assumed distribution or mixture of distributions.
- How deep it goes
- Explains distributional assumptions, covariance structure, GMM parameters, and iterative EM fitting without theoretical derivation.
- Examples
- Uses single Gaussian ellipses, three-cluster GMMs, weighted overlap regions, and synthetic clustered data containing outliers.
- What you can do after
- Evaluate and apply distribution-based outlier detectors when their structural assumptions plausibly match the data.

Digital Twins in Action
A parametric model defines geometry through mathematical relationships and constraints so that changes to parameters update dependent geometry.
- How it is used
- Supports precision-sensitive design iteration and reconfigurable geometry in digital twins.
- How deep it goes
- Defines constraints and works through a cylinder dependency, but does not provide a CAD construction procedure.
- Examples
- Uses a cylinder whose height tracks its radius and a CAD-derived rendering of an offshore platform.
- What you can do after
- Evaluate/understand it by choosing parametric geometry for precise design changes rather than browser-oriented visualization alone.
