This article discusses the dimensionality of behavior in animal behavior physics, including the definition of continuous trajectories and discrete state sequences and situations where the dimensionality of behavior is effectively infinite.
There is a growing effort in the physics of behavior that aims at complete quantitative characterization of animal movements under more complex, naturalistic conditions. One reaction to the resulting explosion of high-dimensional data is the search for low-dimensional structure. Here I try to define more clearly what we mean by the dimensionality of behavior, where observable behavior may consist of either continuous trajectories or sequences of discrete states. This discussion also serves to isolate situations in which the dimensionality of behavior is effectively infinite.
