  • Efficient decision tree evaluation
    Patent number: 11281991
    Abstract: A model optimization system can reduce the delays caused by cache misses and page faults by converting a model of one or more decision trees into machine code that is optimized to avoid these memory faults. The model optimization system can convert a model into machine code by converting each tree of the model into a series of nested if/then statements and converting each series of nested if/then statements into optimized machine code. In some implementations, the model can be converted into optimized machine code only when an amount of processing required to convert the model into the optimized machine code is less than the expected cost savings of using the optimized machine code, instead of an unmodified version of the model, over the life of the model.
