This paper studies a hierarchical distributed choice of retransmission probabilities in slotted aloha.
This, coupled with a situation in which the poorest students and their families may not wish to commit to the most expensive degrees (or to any degree), may result in a more hierarchical HE sector where choice is limited by degree affordability.
We model the tradeoff between the balance and the strength of incentives implicit in the choice between hierarchical and matrix organizational structures.
The choice of hierarchical levels should be made to emphasize dynamical relationships, if known.
First, it performs hierarchical searches through a choice of three classifications.
As predicted by the Tinbergen hierarchical model of behavioral choice [ 2], tactile stimuli that evoke whole-body withdrawal responses in Lymnaea significantly inhibit feeding even in the presence of a strong feeding stimulus.
Barnett et al., 2007 differed from Alpérovitch et al., 2009 by its study design (panel vs. cohort) and model choice, a hierarchical model with a season curve and temperature trend.
We now put this forward as a potential hypothesis in the Discussion, but we make clear that it is a hypothesis requiring further investigation (please see: "Further, future spiking network models of choice involving hierarchical competitions across multiple areas the time-course of these inter-regional effects more explicitly".
Future recurrent network models of choice involving hierarchical competitions across multiple areas (Hunt et al., 2014; Chaudhuri et al., 2015) might also capture this distributed approach, and seek to explain our observations concerning the selective effort- and delay-based interactions across areas.
Hierarchical clustering entails making choices, including where to threshold the dendrogram, that are generally informed by a priori predictions about the structure of the underlying data, rather than being prescribed quantitatively (e.g., Ploran et al. 2007; Church et al. 2011).
