Example of trafo for sigma tuning in kernlab #124

Closed MinhAnhL closed 6 years ago

MinhAnhL commented 7 years ago

The example of specifying the search space of the sigma parameter in kernlab might be not correct. I talked to Bernd, the basis of the trafo should be 2 and not 10 (same for the C param?).

makeNumericParam("sigma", lower = -10, upper = 10, trafo = function(x) 10^x)

should be

makeNumericParam("sigma", lower = -12, upper = 12, trafo = function(x) 2^x)
