Abstract: In an example of a method described herein, historical events occurring over a network are detected, and at least one of the historical events is associated with an observed value of a categorical variable. A numerical aggregate value representing the observed value is updated by applying an exponential smoothing function to (i) a prior numerical aggregate value representing prior historical events associated with the observed value and (ii) a count of the historical events associated with the observed value. An event occurring over the network is detected and is associated with the observed value. Features are extracted from the event, where the features include an encoded feature based on the numerical aggregate value to represent the observed value. A predictive model is applied to the features to determine a score representing likelihood of an outcome. Based on the score, access to a resource of the network is controlled.
