WebMar 29, 2024 · A supersom is an extension of self-organising maps (SOMs) to multiple data layers, possibly with different numbers and different types of variables (though equal numbers of objects). NAs are allowed. A weighted distance over all layers is calculated to determine the winning units during training.
