Consider a nonlinear system described by the following equations: ˙x1=x21+x22˙x2=−2x1−3x2+2uy=x1+2 Suppose you usep(t)=˙x1as a scheduling variable. At a given time instantt=t0, you have: ˙x1≈2x1(t0)x1+2x2(t0)x2−˙x1(t0)˙x2=−2x1−3x2+2uy=x1+2 ...
Documentation Examples Functions Blocks Apps Videos Answers Generalized Linear Models What Are Generalized Linear Models? Linear regression models describe a linear relationship between a response and one or more predictive terms. Many times, however, a nonlinear relationship exists. Nonlinear Regression ...

=== There are some large data for which with/without nonlinear mappings gives similar performances. Without using kernels, one can efficiently train a much larger set via linear classification/regression. These data usually have a large number of features. Document classification is an example...

Before turning to nonlinear situations, let us consider two specific examples of coupled linear systems. The first describes the dynamic behavior of a multireservoir system; the second represents a steady-state situation of an open two-reservoir system. Example 1. As a specific example of a time...
Multiple regressions can be linear and nonlinear. MLRs are based on the assumption that there is a linear relationship between both the dependent and independent variables. It also assumes no major correlation between the independent variables. ...
