1. An alarm analysis method, comprising:
determining M alarm pairs in a first alarm set, wherein each alarm pair of the M alarm pairs comprises a first alarm and a second alarm between which an association exists, and wherein M is an integer greater than 0;
generating, according to an association rule, a first feature set of N alarm pairs of the M alarm pairs, wherein the first alarm of each alarm pair of the N alarm pairs is used as an alarm pair root in the first feature set, wherein the first feature set comprises a first probability that a first subsystem to which each first alarm in the N alarm pairs belongs is a subsystem root and a first alarm object corresponding to the first alarm is an alarm object root and further comprises a second probability that a second subsystem to which each second alarm of the N alarm pairs belongs is a subsystem root and a second alarm object corresponding to the second alarm is an alarm object root, and wherein N is an integer greater than 0 and less than M; and
determining root information of the first alarm set based on the first probability and the second probability, wherein the root information comprises one or more of a root alarm, a root subsystem, or a root alarm object in the first alarm set.
