Numerosity reductionMatrix decompositionSubspace learningOne way to deal with the ever increasing amount of available data for processing is to rank data instances by usefulness and reduce the dataset size. In this work, we introduce a framework to achieve this using matrix decomposition and subspace ...
Previous work has shown that when arrays of objects are grouped within clusters, participants can enumerate their numerosity more rapidly than when objects are randomly scattered, a phenomenon termed “groupitizing”. Importantly, the magnitude of the gr
It was expected that decreases in numerosity would be accompanied by decreases in the magnitude of distance estimates. Numerosity reduction did have a slight but significant effect in the expected direction.doi:10.3758/BF03327993John C. BairdSpringer-VerlagPsychonomic Science...
1670Accesses 5Altmetric Metrics Abstract To estimate the number of objects in an image, each element needs to be segregated as a single unit. Several principles guide the process of element identification, one of the strongest being symmetry. In the current study, we investigated how symmetry affe...
In this case, the function generally lies below the dotted lines (see Figure 3); that is, the apparent reduction in numerosity for patterns com- posed from 48 dots (tJ.N = 8) exceeds 8 dots. In general, the results agree with data reported by Gins- burg and Goldstein (1987). The ...
Prior event uncertainty reduction under two different levels of time uncertainty of foreperiod duration in schizophrenia Judgment of stimulus duration was found to be a monotonically increasing function of both foreperiod duration and numerosity of dots. When pitch of sound, which functioned as a warni...
