Non-ambiguous trees: New results and generalisation

Combinatorics of non - ambiguous trees † ‡

This article investigates combinatorial properties of non-ambiguous trees. These objects we define may be seen either as binary trees drawn on a grid with some constraints, or as a subset of the tree-like tableaux previously defined by Aval, Boussicault and Nadeau. The enumeration of non-ambiguous trees satisfying some additional constraints allows us to give elegant combinatorial proofs of ide...

Neuropsychology of Aesthetic Judgment of Ambiguous and Non-Ambiguous Artworks

Several affective and cognitive processes have been found to be pivotal in affecting aesthetic experience of artworks and both neuropsychological as well as psychiatric symptoms have been found to affect artistic production. However, there is a paucity of studies directly investigating effects of brain lesions on aesthetic judgment. Here, we assessed the effects of unilateral brain damage on ae...

Ambiguous POMDPs: Structural Results and Applications

Markov Decision Processes (MDPs) and their generalization, Partially Observable MDPs (POMDPs), have been widely studied and used as invaluable tools in dynamic stochastic decision-making. However, two major barriers have limited their application for problems arising in various practical settings: (a) computational challenges for problems with large state or action spaces, and (b) ambiguity in ...
