Claim 10:
11. A method comprising:
receiving, by one or more processors in communication with a memory, a set of training data comprising a plurality of calls into an interactive voice response (IVR) system, wherein the plurality of calls included in the set of training data includes a group of fraudulent calls and a group of non-fraudulent calls, and wherein the memory is configured to store a deep learning model;
identifying, by the one or more processors, an activity pattern corresponding to each call of the plurality of calls based on a sequence of code pairs corresponding to each call of the plurality of calls;
training, by the one or more processors, the deep learning model using the activity pattern corresponding to each call of the plurality of calls; and
identifying, during training by the deep learning model and based on the activity pattern corresponding to each call of the plurality of calls, a plurality of patterns associated with the group of fraudulent calls included in the set of training data and a plurality of patterns associated with the group of non-fraudulent calls included in the set of training data.
