A Study of a Hybrid Parallel SOM Algorithm for Large Maps in Data Mining
December 2008
Silva2008
The present thesis addresses a particular kind of neural network called Self-Organized Map (SOM), in particular the use of large maps for Data Mining purposes and the parallel training of the algorithm. [...] The SOM algorithm can be made parallel in several ways, featuring different granularity in execution. In general, parallel implementations of the SOM are developed by either partitioning the map (Network-Partitioning), partitioning the input data (Data-Partitioning) or partitioning the weights of the neurons (Weight-Partitioning) among the available processing units. By exploiting particular characteristics of the SOM training process, a algorithm that combines two of these common approaches, therefore called Hybrid, was devise, tested and studied.
