Understanding Popout through Repulsion

Perceptual popout is defined by both feature similarity and local feature contrast. We identify these two measures with attraction and repulsion, and unify the dual processes of association by attraction and segregation by repulsion in a single grouping framework. We generalize normalized cuts to multi-way partitioning with these dual measures. We expand graph partitioning approaches to weight ...

Latency effects in orientation popout

A target that differs in orientation from neighboring lines and "pops out" has been found to evoke larger responses in cortical V1 cells than lines in the uniform texture surround which do not popout (e.g., Journal of Neurophysiology 67 (1992) 961). If this is more than a coincidence of observations, physiological properties of contextual modulation should be reflected in the perception of sali...

Novelty and Adaptive Novelty

In this paper we briefly describe Novelty and Adaptive Novelty, two high-performance, stochastic local search (SLS) algorithms for SAT. Based on the WalkSAT architecture, these algorithms combine search intensification and diversification feautures that lead to good peformance on a broad range of SAT instances. The performance of the Novelty algorithm critically depends on the setting of a soca...

A Novel Approach to Understanding Novelty Effects in Memory

Enhanced memory for oddball items has been long established, but the basis for these effects is not well understood. The present work offers a novel way to think about novelty that clarifies the roles of isolation and differentiation in establishing new memories. According to the isolation account, items that are highly dissimilar to other items are better remembered. In contrast, recent catego...
