I've come to the conclusion, that not assuming binary classification makes no sense, since every n-class classification problem can be split into n binary classification problems.
When assuming classes 0 and 1, the performance increases and I get to: cpu time: 608 real time: 605 gc time: 68 For finding the best split. Daniel's solution makes use of multiple return values, which were new to me. I am using a struct for this, which might be unnecessary and later removed in favor of returning multiple values like in Daniel's solution. -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
