A growth equation of the stand topping mean height was created by using artificial neural network modeling technology, in Masson pine planted forest. Then, a site index model was created with the created equation as the directed equation, and the site index curved shape was drawn with the method of index level adjustment. Finally, the table of site index was worked out. The model structure is 1∶3∶1,...
Taking the boiling point of fatty alcohols for research object, the paper analyzes the relationship between the characteristic parameters of fatty alcohols and its boilling point with ANN and stepwise regression analysis. A ANN model for calibration analysis on point of fatty alcohols was created by using Wiener index, atomic position index, and molecular connectivity index as input variables and...
