Web13 Aug 2024 · Since ccp_alpha is also a parameter to tune, it should be a part of your CV. Your other parameters depend on that too. It is a regularization parameter (like lambda in Lasso/Ridge regression) thus a high value gives you very small trees. WebCCP (Cost Complexity Pruning) is one of the most prominent techniques used for post-pruning, CCP Alpha is the parameter being used for controlling the post-pruning process, with the increase in the value for ccp_alpha, more nodes from a given tree are pruned.
