The disclosed computer-implemented method for updating a machine-learning-based prediction model with preserved privacy may include receiving a plurality of training data sets for training a machine-learning-based global prediction model for predicting future incidents of a computing event. Each data set may include incidents of the computing event. The method may include creating, by training the global prediction model using the plurality of training data sets, an intermediate prediction model of the global prediction model. The intermediate prediction model may be a precursor state to a fully trained global prediction model. The method may further include providing the intermediate prediction model to a computing node to enable the computing node to fully train a local prediction model using both the intermediate prediction model and a local training data set. Various other methods, systems, and computer-readable media are also disclosed.

Systems and methods for updating a machine-learning-based prediction model with preserved privacy

The disclosed computer-implemented method for utilizing federated machine-learning to protect against potentially malicious data may include (i) arranging a set of client devices into groups for applying a federated machine-learning model, (ii) determining model updates for each of the groups over a predetermined period, (iii) training one or more recurrent neural networks to derive a low-dimensional representation of the model updates, (iv) calculating a data quality score for each of the client devices based on the model updates, (v) applying the federated machine-learning model to classify data instances on each of the client devices as including clean data or potentially corrupt data, and (vi) performing a security action that protects against the potentially malicious data by tagging the data instances classified as the potentially corrupt data. Various other methods, systems, and computer-readable media are also disclosed.
