Support vector machine regression LibSVM and PSO

ismail_hdoufane

Dear Community,

I am a new user. I have an xls file which contains 159 rows and 13 columns.

1st column contains values of biological activity (Y) and the others contain(molecular descriptors) (Xi)

I would like to do Regression for building model using Support Vector Machine LibSVM and PSO.

Best Regards,

Ismail

You will need a Read Excel, Set Role, Cross Validation, LibSVM, Apply Model and Performance operators as a starting point for your process. Something like this below:

< portSpacing端口= " sink_through 1”间隔= " 0 " / >





<运营商激活= " true "类= com“性能”patibility="7.6.002" expanded="true" height="82" name="Performance" width="90" x="179" y="34"/>











Applies the model built from the training data set on the current test set (10 % by default).<br/>The Performance operator calculates performance indicators and sends them to the operator result.

A cross validation including a linear regression.

To expand a bit on the topic: what are the big differences between the SVM operator and the LibSVM one? When would you use one instead of the other?
