Hi, I am using the Support Vector Regression, using fitrsvm (https://uk.mathworks.com/help/stats/fitrsvm.html). I would like to know how to plot the Kernel chosen, just like it is mentioned in this video https://youtu.be/-Z4aojJ-pdg . How to do this?

Hi,

The youtube link you provided doesn't work. I assume you want the Kernel Function and Scale used, which is provided in Kernel Parameters Structure after fitting the model using 'fitrsvm'.

Refer to fitrsvm documentation for more info:

Hi, I've looking into this. What I mean is hwo to plot the objective function model of the SVR. Matlab provides some information about this but doesn't say how to make the plot.

https://uk.mathworks.com/help/stats/fitcsvm.html?searchHighlight=fitcsvm&s_tid=doc_srchtitle

How to use and plot the regression model. I want to use the SVR model to test it other data that is not originally in the set of predictors data.
