To Google or Not to Google

The goal of metasearch systems is to facilitate access for researchers—both novice and expert users—to the ever-growing number of scholarly electronic resources. Researchers today are typically Web-savvy and have high expectations regarding ease of access to information for their research needs. Facing the variety and complexity of the interfaces provided by information providers, researchers o...

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...
