Artificial intelligence system for network traffic flow based detection of service usage policy violations

At an artificial intelligence based service to detect violations of resource usage policies, an indication of a first data set comprising a plurality of network traffic flow records associated with at least a first device of a set of devices may be obtained. Using the first data set, a machine learning model may be trained to predict whether resource usage of a particular device of a particular network violates a first resource usage acceptability criterion. In response to determining, using a trained version of the model, that the probability that a second device has violated the acceptability criterion exceeds a threshold, one or more actions responsive to the violation may be initiated.
