1. A decision tree system, comprising:
- a module to read the data and use the data to create multiple decision trees having nodes, a module to sort the data, a module to evaluate a potential split of the data according to some criterion, using a random sample of the data at said nodes, a module to split the data, and a module to combine said multiple decision trees in ensembles.

Abstract
A system for decision tree ensembles that includes a module to read the data, a module to sort the data, a module to evaluate a potential split of the data according to some criterion using a random sample of the data, a module to split the data, and a module to combine multiple decision trees in ensembles. The decision tree method is based on statistical sampling techniques and includes the steps of reading the data; sorting the data; evaluating a potential split according to some criterion using a random sample of the data, splitting the data, and combining multiple decision trees in ensembles.
