representation of goals in a pedestrian
mobility model, see (Brambilla & Cattelani,
2009).
Doing computations for each possible
association of targets in the particle and
targets in the observation is very expensive,
since the computational complexity is
exponential in the number of targets. Less
expensive approximations might be
investigated.
An interesting challenge would be the
automatic extraction of relevant relations
starting from data. Similar results on
Bayesian networks and probabilistic
relational models exist (Getoor, Friedman,
Koller & Pfeffer, 2001).
