TRANSLATE REGRESSION TREE / DECEION TREE TO SQL-LIKE RULES
3 views (last 30 days)
I am interested in translating decision tree (regression/classification) to SQL Rule format. For example, the decision tree below, when rules are converted to SQL, it should output something like this.
I want to deploy the tree model in sql environment.
If x2 >= 3085.5 and x1 >= 115 then 14.375
If x2 >= 3085.5 and x1 < 115 then 19.625
If x2 < 3085.5 and x1 <89 and x2 <2162 then 33.3056
Until all rules/possible paths are completed.
The view(tree) function is not meeting my requirement.
Is there a code /function that does this? I would be ggrateful for help.

Currently there is no MATLAB function to parse the classification tree objects and print out the path to all the leaves. This specific use case can be built using the properties which the ClassificationTree class provides. Have a look at the properties of this class and use any of the algorithms to print all the root to leaf paths in a tree. A similar implementation for the same has been answered here.
