The current state of the art methods for semi-supervised regression are based on supervised manifold regularization. In contrast, the latent data constructed by the proposed method jointly reconstructs both the observed predictors and target variables via generative-style nonlinear functions. Dual-form ...

Despite its name, you can fit curves using linear regression. The most common method is to include polynomial terms in the linear model. Polynomial terms are independent variables that you raise to a power, such as squared or cubed terms. Learn more aboutlinear regression. To determine the cor...

Nonlinear regression minimizes the sum of the squared vertical distances between the data point and the curve. In other words, nonlinear regression adjusts the parameters of the model to minimize the sum of (Ydata- Ycurve)2. If you choose, ...
A model is nonlinear if any of the partial derivatives with respect to any of the model parameters are dependent on any other model parameter or if any of the derivatives do not exist or are discontinuous. This chapter expands on the previous chapter and introduces nonlinear regression within a...
