WebSo, in intuitive terms, we can think of a non-parametric model as a “distribution” or (quasi) assumption-free model. However, keep in mind that the definitions of “parametric” and “non-parametric” are “a bit ambiguous” at best; according to the “The Handbook of Nonparametric Statistics 1 (1962) on p. 2: “A precise and ... WebParametric vs. non-parametric. To define parametric machine learning models we have two options: Option 1: Parametric machine learning models are those using fixed number of parameters. The opposite would be those models having 0 or infinite number of parameters. Option 2: Structure of parametric machine learning models can be specified a ...
