  • Decision tree ensemble compilation
    Patent number: 9864589
    Abstract: In one embodiment, a method includes generating an executable version of a decision tree by compiling source code into executable code and verifying the executable code by comparing a result of executing the executable code with a result of evaluating the decision tree in interpreted mode. The method further includes replacing the decision tree evaluated in the interpreted mode with the executable code if the executable code is verified or discarding the executable code otherwise.
    Type: Grant

  • Decision tree ensemble compilation
    Patent number: 9678730
    Abstract: In one embodiment, a decision tree is evaluated in interpreted mode while statistics are collected. The decision tree is then represented as source code, and each decision in the decision tree is annotated with instructions determined based on the collected statistics. The source code is compiled into machine code, and the machine code is optimized based on the instructions annotating each decision in the decision tree.
