repeated execution of svm(e1071) gives different results, if probability = TRUE is set
...code example. You can run it a few times.
library('e1071')
prob <- function() {
model <- svm(Species ~ ., data = iris[-1,], probability=TRUE)
p <- predict(model, newdata=iris[1,], probability=TRUE)
pr <- attr(p, "probabilities")
print(pr)
return(pr)
}
cat('FirstCalc==SecondCalc:',all( prob() == prob() ),'\n')
