Introducing self-organized maps (SOM) as a visualization tool for materials research and educationMaterials informatics is an emerging discipline that opens a new paradigm of science: data-driven materials discovery. The visualization of high dimensional material properties data is challenging due to a ...
The Self-Organizing Map(SOM)is a neural network model. It consists of neurons organized in array. The number of the neurons may vary from a few dozen up to several thousand. Consider a rolling mill from which several measurements are taken, as mentioned above. Denote the measurement vector ...

Fine tuning the map by learning vector quantization is addressed. The use of self-organized maps in practical speech recognition and a simulation experiment on semantic mapping are discussed.> 展开 关键词: Biological neural networks Artificial neural networks Pattern recognition Process control Signal ...
This paper proposes a model to support decision making based on self-organized maps. This model, applied to electronic government tools, can recognize patterns in large volume of data without the set of rules for training. To perform our case study, we use data provided by the city of ...
b The self-organized topology pattern of the trained color mapping SOM. Each pattern is represented as the output neuron response. The chosen eight weight vectors in the memristor array (in the red box of a) represents the weights of the nodes in the 6th row of 2D SOM. The color of ...
The method is applied on a realistic model of the Hellenic power system and its added value is shown by comparing results with the ones obtained from the application of simple self-organized maps and simple decision trees. 展开 关键词: decision trees learning (artificial intelligence) load ...
This network has one layer, with neurons organized in a grid. Self-organizing maps learn to cluster data based on similarity. For more information on the SOM, see Cluster with Self-Organizing Map Neural Network. To create the network, specify the map size, this corresponds to the number ...
In order to use MiniSom you need your data organized as a Numpy matrix where each row corresponds to an observation or as list of lists like the following: data = [[ 0.80, 0.55, 0.22, 0.03], [ 0.82, 0.50, 0.23, 0.03], [ 0.80, 0.54, 0.22, 0.03], [ 0.80, 0.53, 0.26, 0.03],...
An ocean surface currents forecasting system, based on a Self-Organizing Maps (SOM) neural network algorithm, high-frequency (HF) ocean radar measurements and numerical weather prediction (NWP) products, has been developed for a coastal area of the north
