I think you need to be more specific. Outlier detection?
Pattern detection?
When I start up my computer, I sometimes kill time
by watching the CPU/memory statistics in Task Manager.
I see Firefox grab a few megabytes at a time until it gets
to 360 MB, while starting and opening 4 or 5 tabs. That
memory usage, I suppose, is an "irregular pattern" in
two senses. It is not monotonic, so it is irregular as a linear
increase; and it only happens once in a session, so the
increase is a one-time shot in the overall computer memory
usage for the session.
Neither of these seems mysterious enough to be interesting.
What would seem more interesting is if someone found a way
to detect a "memory leak" which would be a *regular* pattern.
