Abstract: In examples, an apparatus comprises: a memory, and a processor coupled to the memory. The processor to: adaptively order an ordered set of regular expressions based on training messages to produce a set of adaptively ordered regular expressions having an adaptive order, determine a first of the adaptively ordered regular expressions that matches an additional message, and determine whether a second of the adaptively ordered regular expressions matches the additional message. Responsive to determining that the second of the other of the adaptively ordered regular expressions matches the additional message, the processor to: classify the additional message with the first regular expression if the first regular expression has a higher priority in the adaptive order; and classify the additional message with the second regular expression if the second regular expression has a higher priority in the adaptive order.
