Zipfian Regularities in Non-point Word Representations

Zipfian regularities are important empirical laws in computational linguistics and natural language processing as well as several other areas of science. Zipf’s law of meaning distribution, one of the most important Zipfian laws, points out a power relation between frequencies of words and number of meanings that words have. In particular, frequent words have more […]

Discrete Scaling based on Operator Theory

Discrete signal scaling is a basic operation of central importance that poses several challenges, which are usually addressed as an interpolation problem. Our approach, which does not involve interpolation in the conventional sense, provides a novel and unique perspective to this problem, and may be useful in a wide variety of theoretical and practical contexts. […]

Dynamic dot displays reveal material motion network in the human brain

Using dynamic dot displays, Schimid et al. show that a large network of brain regions respond to material motion. The dynamic dot displays are similar to those in biological motion studies, and they allow researchers to isolate motion cues from all other cues to material properties (e.g. surface reflectance). Interestingly, the areas that are found […]
