Common-fate grouping as feature selection.
The visual system groups elements within the visual field that are physically separated yet similar to each other. Although grouping processes have been intensely studied for a century, the mechanisms of grouping remain elusive. We propose that a primary mechanism for grouping by common fate is attentional selection of a direction of motion. A unique prediction follows from this account: that t...
متن کاملUnsupervised Feature Selection Using Feature Similarity
ÐIn this article, we describe an unsupervised feature selection algorithm suitable for data sets, large in both dimension and size. The method is based on measuring similarity between features whereby redundancy therein is removed. This does not need any search and, therefore, is fast. A new feature similarity measure, called maximum information compression index, is introduced. The algorithm i...
متن کاملFeature selection using structural similarity
A new method of feature selection is developed, based on structural similarity. The topological neighborhood information about pairs of objects (or patterns), to partition(s), is taken into consideration while computing a measure of structural similarity. This is termed proximity, and is defined in terms of membership values. Multi-objective evolutionary optimization is employed to arrive at a ...
متن کاملDoes feature similarity facilitate attentional selection?
Object-based attention enables us to simultaneously select and report two features from the same visual object. Does feature-based attention contribute similarly to visual selection? In the present study, we investigated the concurrent discrimination of two motion fields with a divided attention paradigm. We found that dual-task performance improved when the two fields conformed to a continuous...
متن کاملContext Feature Selection for Distributional Similarity
Distributional similarity is a widely used concept to capture the semantic relatedness of words in various NLP tasks. However, accurate similarity calculation requires a large number of contexts, which leads to impractically high computational complexity. To alleviate the problem, we have investigated the effectiveness of automatic context selection by applying feature selection methods explore...
