The Salford Systems data mining solution rests on two groups of technologies: CART, MARS, and PRIM for accurate, easy-to-understand models, and TreeNet® and RandomForests® for ultra-high performance, potentially complex models interpreted via supporting graphical displays. Even in circumstances where interpretability and transparency are mandatory and a model must be expressed in the form of rules, TreeNet can serve a useful function by benchmarking the maximum achievable accuracy against which interpretable models can be compared.
