matlab中的一节点决策树

Question

Im using matlab 2014a and I cant find how to do 1 node decision tree (and 2 nodes, 3 nodes ext.) Itried to use:

"MaxNumSplits",and "MaxDepth"

but I got

MaxNumSplits is not a valid parameter name.

thanks ahead

Answer 1

Your version of Matlab is too old for manipulating the MaxNumSplits parameter.

Matlab's way of implementing algorithms changes along time. This is the case here for fitctree (fit classification tree) when the R2015a version was released. See the following 'new features' page introducing 2 new parameters for the fitctree function

Additional option to control decision tree depth using 'MaxNumSplits' argument in fitctree, fitrtree, and templateTree functions

You can search such evolution by comparing the different versions of the docs here: https://de.mathworks.com/help/doc-archives.html
