Working Order

A probabilistic model of visual working memory: Incorporating higher order regularities into working memory capacity estimates.

When remembering a real-world scene, people encode both detailed information about specific objects and higher order information like the overall gist of the scene. However, formal models of change detection, like those used to estimate visual working memory capacity, assume observers encode only a simple memory representation that includes no higher order structure and treats items independent...

Neural measures link attention and serial order in working memory

Working memory, the focus of intensive behavioural, neural, and computational study, is integral to a wide range of human intellectual achievements 1, 2. One of working memory's notable attributes, its limited capacity, has been linked to limitations on attentional resources 2-13. We asked whether attention might also govern the second of working memory's key attributes, the serial ordering of ...

Working Orders in Limit Order Markets and Floor Exchanges

We analyze limit order markets and floor exchanges, assuming an informed trader and discretionary liquidity traders use market orders and can either submit block orders or work their demands as a series of small orders. By working their demands, large market order traders pool with small traders. We show that every equilibrium on a floor exchange must involve at least partial pooling. Moreover,...

Distributed second order methods with variable number of working nodes

February 21, 2017 Abstract Recently, an idling mechanism has been introduced in the context of distributed first order methods for minimization of a sum of nodes’ local convex costs over a generic, connected network. With the idling mechanism, each node i, at each iteration k, is active – updates its solution estimate and exchanges messages with its network neighborhood – with probability pk (p...
