Abstract
Features of sample files that are known to be normal are extracted by random projection. The random projection values of the sample files are used as training data to generate one or more anomaly detection models. Features of a target file being inspected are extracted by generating a random projection value of the target file. The random projection value of the target file is input to an anomaly detection model to determine whether or not the target file has features that are novel relative to the sample files. The target file is declared to be an outlier when an anomaly detection model generates an inference that indicates that the target file has novel features.
