Nonlinear system identification. System identification is a method of identifying or measuring the mathematical model of a system from measurements of the system inputs and outputs. The applications of system identification include any system where the inputs and outputs can be measured and include industrial processes, control systems ...
Nonlinear control theory is the area of control theory which deals with systems that are nonlinear, time-variant, or both. Control theory is an interdisciplinary branch of engineering and mathematics that is concerned with the behavior of dynamical systems with inputs, and how to modify the output by changes in the input using feedback ...
The Shannon–Weaver model is one of the first and most influential models of communication. It was initially published in the 1948 paper "A Mathematical Theory of Communication" and explains communication in terms of five basic components: a source, a transmitter, a channel, a receiver, and a destination. The source produces the original message.
Vector generalized additive models. Vector generalized additive models (VGAMs) are a major extension to VGLMs in which the linear predictor is not restricted to be linear in the covariates but is the sum of smoothing functions applied to the : where These are M additive predictors . Each smooth function is estimated from the data.
The main approaches for stepwise regression are: Forward selection, which involves starting with no variables in the model, testing the addition of each variable using a chosen model fit criterion, adding the variable (if any) whose inclusion gives the most statistically significant improvement of the fit, and repeating this process until none improves the model to a statistically significant ...
Multivariate adaptive regression spline. In statistics, multivariate adaptive regression splines ( MARS) is a form of regression analysis introduced by Jerome H. Friedman in 1991. [ 1] It is a non-parametric regression technique and can be seen as an extension of linear models that automatically models nonlinearities and interactions between ...
A 2004 non-peer-reviewed literature review criticized most of the main instruments used to identify an individual's learning style. [1] In conducting the review, Frank Coffield and his colleagues selected 13 of the most influential models of the 71 models they identified, [1]: 8–9 including most of the models described in this article. They ...
