Abstract
Methods and systems for detecting and correcting model shift in machine learning models are disclosed. A computer can receive a set of input data from a data source. The computer can apply the input data to a machine learning model to produce a first set of classification data. The computer can perform a metadata test and validate the current machine learning model and the set of input data using a plurality of previously generated machine learning models. The plurality of previously generated machine learning models can produce a plurality of sets of classification data, which can be compared to the first set of classification data. Based on the comparison, the computer can determine whether the set of input data is associated with a malicious entity.
