While visual search is known to be heavily guided by visual features similar to those in the search target, little is known about how we select the feature dimensions – such as luminance or orientation to guide search so efficiently. Here we introduce a novel measure of the informativeness of individual feature dimensions for a given search task. By analyzing human eye movements during search i...

Whether return synchronicity is associated with higher or lower stock price informativeness still an ongoing debate in the academic literature. This paper contributes to this by exploiting exogenous shock, provided a regulatory change introduced Federal Reserve 2015, and examining its impact on using sample of U.S. listed bank holding companies (BHCs) operating during period 2014: Q3 – 2016: Q2...

Blackwell (1951, 1953) proposes an informativeness ranking of experiments: Experiment I is more Blackwell-informative than Experiment II if and only if the value of experiment I is higher than that of experiment II for all expected-utility maximizers. Under commitment and reduction, our main theorem shows that Blackwell equivalence holds for all convex and strongly monotone preferences, i.e., t...

In the process of designing pattern recognition systems one may choose a representation based on pairwise dissimilarities between objects. This is especially appealing when a set of discriminative features is difficult to find. Various classification systems have been studied for such a dissimilarity representation: the direct use of the nearest neighbor rule, the postulation of a dissimilarity...

In many pattern recognition applications object structure is essential for the discrimination purpose. In such cases researchers often use recognition schemes based on template matching which lead to the design of non-Euclidean dissimilarity measures. A vector space derived from the embedding of the dissimilarities is desirable in order to use general classifiers. An isometric embedding of the ...
