Analyzing House Fly's Exploration Behavior with AR Methods

This paper presents a detailed characterization of the trajectory of a single housefly freely walking in a square cage. The trajectory of the fly is recorded and transformed into time series, which is fully analyzed by the method of AR model. A main discovery is that the fly switches the styles of motion from the low dimensional regular pattern to the higher dimensional disordered pattern. In particular, the anomalous diffusion is found to well characterize the fly’s exploration behavior. The exploration behavior analysis is important form both psychological and dynamical system’ point of view.
