I have a fitted model for SVM Gaussian regression. I have derived that or obtained that from the Stats and Machine Learning Toolbox. I now want to deply that in VBA on my machine, and demo the model to fellow engineers. I can't seem to locate teh form of teh equation and coefficients. I know what a Gaussian kernel is and all that, but where are the coefficients? Thanks for your help

在 MATLAB Online 中打开

To extract Weight_Vector from SVM Model :

Weight_vector = SVMModel.Alpha' * SVMModel.SupportVectors; 
% To extract Bias Value from SVM Model
Bias = SVMModel.Bias;  
% Now to write these into a file 
writematrix(Weight_vector, ‘weight_vector.csv’ ); 
writematrix(Bias, ‘bias.csv’); 

Refer the following link for “writematrix()” function

Thank you. Is the exact form of the SVM equation defined in some readily available text? I am familiar with the math behind RBF and general NN and so I would like to follow this up.
