An abstract theory of sensor eventification
Yulin Zhang, Dylan A. Shell
Unlike traditional cameras, event cameras measure changes in light intensity and report differences. This paper examines the conditions necessary for other traditional sensors to a…
A general class of combinatorial filters that can be minimized efficiently
Yulin Zhang, Dylan A. Shell
State minimization of combinatorial filters is a fundamental problem that arises, for example, in building cheap, resource-efficient robots. But exact minimization is known to be N…
Nondeterminism subject to output commitment in combinatorial filters
Yulin Zhang, Dylan A. Shell
We study a class of filters -- discrete finite-state transition systems employed as incremental stream transducers -- that have application to robotics: e.g., to model combinatoria…
On nondeterminism in combinatorial filters
Yulin Zhang, Dylan A. Shell
The problem of combinatorial filter reduction arises from questions of resource optimization in robots; it is one specific way in which automation can help to achieve minimalism, t…
Lattices of sensors reconsidered when less information is preferred
Yulin Zhang, Dylan A. Shell
To treat sensing limitations (with uncertainty in both conflation of information and noise) we model sensors as covers. This leads to a semilattice organization of abstract sensors…
