How Tall Is Tall? Compositionality, Statistics, and Gradable Adjectives

What is tall? Like many words, tall is fundamentally compositional in meaning — whether an item is tall depends on the statistical properties of the set of items it is being compared to. Despite preliminary evidence to this effect, no mathematical models of how tall operates in a given context have ever been empirically evaluated. We compare a number of statistical models to adults and children...

3D SOM Neighborhood Algorithm

Neighborhood algorithm is an important part of 3D SOM algorithm. We proposed three kinds of neighborhood shape and two kinds of neighborhood decay function for threedimensional self-organizing feature maps (3D SOM) algorithm and applied them to three-dimensional image compression coding. Experimental results show that the 3D orthogonal cross neighborhood shape and exponential function algorithm...

SOM in data mining

Topology Preservation in SOM

The SOM has several beneficial features which make it a useful method for data mining. One of the most important features is the ability to preserve the topology in the projection. There are several measures that can be used to quantify the goodness of the map in order to obtain the optimal projection, including the average quantization error and many topological errors. Many researches have st...
