Use the generated decision tree to predict new inputs

Question

I want to use the accord.net environment to generate a decision tree from a dataset.

I managed to generate a tree following it. However, how to use it to predict new entries?

what I mean, after creating the tree that I want to use (as an if-else statement, to find out the output of the new inputs)

indicated that I can convert it to an expression var expression = tree.ToExpression();, but how to use it?

Thanks for any help

. var expression = tree.ToExpression(); :

var func = expression.Compile();

bool willPlayTennis = func(new double[] {1.0, 1.0, 1.0, 1.0}) == 1;
