Abstract: A system and method may determine if a class of process (e.g. NN execution, cryptocurrency mining, graphic processing) is executing on a processor, or which class is executing, by calculating or determining features from execution telemetry or measurements collected from processors executing processes, and determining from at least a subset of the features the likelihood that the processor is executing the class of process. Execution telemetry may include data regarding or describing the execution of the process, or describing hardware used to execute the process, such as processor temperature, memory usage, etc.
