Experiments present a comparison between a standard SOM and multilevel SOM for classification of pattern for five different datasets. Principal component initialization is preferable in dimension one if the principal curve approximating the dataset can be univalently and linearly projected on the first principal component quasilinear sets. Like most artificial neural networks, SOMs operate in two modes: training and mapping. Zinovyev, Principal manifolds and graphs in practice: from molecular biology to dynamical systemsInternational Journal of Neural SystemsVol. Abstract Classification is one of the most active research and application areas of neural networks. When a training example is fed to the network, its Euclidean distance to all weight vectors is computed.

    The Visual Computer. If two inputs have similar weight planes their color gradients may be the same or in reverse it indicates they are highly correlated. Selection of a good initial approximation is a well-known problem for all iterative methods of learning neural networks. Connections which are bright indicate highly connected areas of the input space. June Learn how and when to remove this template message.

    Select the China site in Chinese or English for best site performance. Originally, SOM was not formulated as a solution to an optimisation problem. The weights may initially be set to random values. While representing input data as vectors has been emphasized in this article, any kind of object which can be represented digitally, which has an appropriate distance measure associated with it, and in which the necessary operations for training are possible can be used to construct a self-organizing map.

    We will try a 2-dimension layer of 64 neurons arranged in an 8x8 hexagonal grid for this example. Areas of neurons with large numbers of hits indicate classes representing similar highly populated regions of the feature space.
