Traverse the trees in a Random Forest ensemble and count the number of times each feature index appears over all the trees
A sequence of pairs (idx, n) where 'idx' is a feature index and 'n' is the number of times it was used in the ensemble's trees, sorted in descending order of counts.

Evaluate an input feature vector and return a vector of the leaf-node ids that the feature vector "landed" at for each tree in the RF ensemble
Evaluate an input feature vector and return a vector of the leaf-node ids that the feature vector "landed" at for each tree in the RF ensemble

vector of leaf node ids, one from each tree in the ensemble
Traverse the trees in a Random Forest ensemble and convert each path from root to a leaf into a "rule" that is a sequence of individual predicates representing the decision made at each internal node.

a partial function that returns name of a feature given its index
a partial function from feature index to number of categories. If an index is not present then it is assumed to be numeric
a map from leaf-node prediction values to a collection of all rules that will yield that value.
