I've tried using all sorts of combinations for nFolds, minSize and maxDepth, and perhaps tried using stopping randomizing the choice of data scenarios into Folds. Having said that, my scores usually do not improve, and my necessarily mean accuracy has not exceeded sixty%, and in reality continually is within the 55%+ vary.
As being a consequence, these languages are unsuccessful to get Turing complete and expressing certain features in them is extremely hard, but they could even now express a large class of attention-grabbing computations whilst preventing the issues launched by unrestricted recursion. Useful programming limited to well-Launched recursion by using a several other constraints is termed full useful programming.
