Color along separable spatial dimensions

Iranian's color emotional dimensions

Integrating information from separable psychological dimensions.

This article examines decision processes in the perception and categorization of stimuli composed of the separable psychological dimensions, orientation and size. The randomization technique (Ashby & Gott, 1988) of general recognition theory, which allows accurate estimation of a subject's decision boundary in a categorization task, is used in 4 experiments. Even though the stimulus components ...

Clustering Documents Along Multiple Dimensions

Traditional clustering algorithms are designed to search for a single clustering solution despite the fact that multiple alternative clustering solutions might exist for a particular dataset. For example, a set of news articles might be clustered by topic or by the author’s gender or age. Similarly, book reviews might be clustered by sentiment or comprehensiveness. In this paper, we address the...

Perceptual steps along color scales

Color scales are commonly used to represent numerical information visually. Most scales are derived from some physical or mathematical behavior; even worse, sometimes they are selected based solely on hardware capabilities. In most known cases, no consideration is made to the perceptual capabilities of the human observer, who is ultimately the “consumer” of the information to be delivered by th...

Improving Contact Prediction along Three Dimensions

Correlation patterns in multiple sequence alignments of homologous proteins can be exploited to infer information on the three-dimensional structure of their members. The typical pipeline to address this task, which we in this paper refer to as the three dimensions of contact prediction, is to (i) filter and align the raw sequence data representing the evolutionarily related proteins; (ii) choo...
