Matlab: The SOM Toolbox is built using the MATLAB script language. The layer has a weight from the input, but no bias. Self-organizing maps (SOM) consist of a single layer with the negdist weight function, netsum net input function, and the compet transfer function. The Self-Organizing Map (SOM) is a vector quantization method which places the prototype vectors on a regular low-dimensional grid in an ordered fashion. Self-Organizing Maps Identify prototype vectors for clusters of examples, example distributions, and similarity relationships between clusters MOTIVATION AND APPROACH MIRToolbox is a Matlab toolbox dedicated to the extraction of musically-related features from audio recordings. Also its performance in terms of computational load is evaluated and compared to a corresponding C- program.
