PPT-Nonlinear Dimensionality

Reduction by Locally Linear Embedding Sam T Roweis and Lawrence K Saul Reference Nonlinear dimensionality reduction by locally linear embedding Roweis amp Saul Science 2000. 6 Linearization of Nonlinear Systems In this section we show how to perform linearization of systems described by nonlinear dif ferential equations The procedure introduced is based on the aylor series expansion and Di64256erentiating 8706S 8706f Setting the partial derivatives to 0 produces estimating equations for the regression coe64259cients Because these equations are in general nonlinear they require solution by numerical optimization As in a linear model Framework in .
