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 ...
We describe an intuitive and rapid procedure for analyzing experimental data by nonlinear least-squares fitting (NLSF) in the most widely used spreadsheet program. Experimental data in x/y form and data calculated from a regression equation are inputted and plotted in a Microsoft Excel worksheet, ...

Alternatively, nonlinear regression is a type of regression analysis in which experimental data are represented by a nonlinear function which is a combination of one or more independent variables and model parameters (Giddings and Ratkowsky, 1991). ...
nonlinear regression of curve非线性曲面拟合 3)Nonlinear curve fitting method非线性曲线拟合法 4)non-fitting curve非拟合曲线 1.Based on the mathematical definition and physical meaning, a fast effective method was studied to calculate mathematical inflection point using computer, and a algorithms was pro...
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...

Microsoft Excel's Solver Extension software program was employed for the nonlinear regression of the models, and the result was compared with that of the traditional linear regression technique. The error distribution in the prediction of the model parameters was assessed using various error functions....
In many studies today, artificial neural networks are extensively used to describe and predict a time series. Kumar and Kumar (2021) used a combination of the classical multiplier decomposition model and simple linear regression with NARNN models to predict monthly household waste generation in Nagpur...
