Optimize Parameter/Log for Decision Tree
I'm trying to compare different algorithms and try to find the optimal parameters. For this, I use the optimize parameter operator. However, when I try to apply it to a Decision Tree classifier it doesn't work. Or at least, the log function doesn't work properly, but I also get the same accuracy for each setting.
But when I want to plot it in a log function it only shows one value for each parameter.
Does somebody know why this happens and how I can solve it?
