    abstract  = {This paper focuses on behavior recognition in an underwater application as a
                substitute for communicating through acoustic transmissions, which can be
                unreliable. The importance of this work is that sensor information regarding
                other agents can be leveraged to perform behavior recognition, which is
                activity recognition of robots performing specific programmed behaviors, and
                task-assignment. This work illustrates the use of Behavior Histograms, Hidden
                Markov Models (HMMs), and Conditional Random Fields (CRFs) to perform behavior
                recognition. We present challenges associated with using each behavior
                recognition technique along with results on individually selected test
                trajectories, from simulated and real sonar data, and real-time recognition
                through a simulated mission.}}
