Sequence data classification

Hi all, I have some data sequences, which are simple one dimensional data. When some patterns occur in the sequence, for example, the curve drop down with a certain slope and then quickly comes up, some event is usually associated with it. I would like to do a binary classification, where 1s will denote the happening of such events. My question is, what classifier should I use for solving the problem?

I'd like to post a figure with one curve here. However, it seems that the system only allows using link from other websites.
