发明名称 Enhancing classification and prediction using predictive modeling
摘要 In one embodiment, a system for enhancing predictive modeling includes an interface operable to receive a first dataset. The system may also include a processor communicatively coupled to the interface that is operable to generate a holdout dataset based on the first dataset. The processor may also train each of a plurality of boosting models in parallel using the first dataset, wherein for each of a number of iterations, training comprises: building a one-level binary decision tree to train a split-node variable; calculating an impurity of the split-node variable; and calculating an optimal split node, wherein the optimal split node is the split-node variable with a lowest impurity between the plurality of boosting models. The system may then determine a final model based on one of the plurality of boosting models that provides the lowest error rate when applied to the holdout dataset.

主权项 1. A method for enhancing predictive modeling, comprising: receiving, at an interface, a first dataset; generating, with a processor, a holdout dataset based on the first dataset; training, with the processor, each of a plurality of boosting models in parallel using the first data set, wherein for each of a number of iterations, training comprises: building a one-level binary decision tree to train a split-node variable;calculating an impurity of the split-node variable;calculating an optimal split node, wherein the optimal split node is the split-node variable with a lowest impurity between the plurality of boosting models; andcalculating a total variance for the split node variable; determining a final model, based on one of the plurality of boosting models that provides a lowest error rate when applied to the holdout dataset.
