In certain embodiments, a system comprises a memory operable to maintain a plurality of profiles, an interface operable to receive data comprising a plurality of values, and processing circuitry. The processing circuitry is operable to compress the plurality of values into one or more patterns that summarize information about the plurality of values without storing each of the plurality of values in the one or more patterns. Each pattern is associated with a respective profile of the plurality of profiles based on a relationship between the respective profile and the values used to determine each pattern. The processing circuitry is further operable to determine to apply a rule to a first profile of the plurality of profiles, apply the rule to the one or more patterns associated with the first profile, and communicate a result of applying the rule.
