Self organizing feature map

WebSep 24, 2024 · A self-organizing map (SOM) algorithm can generate a topographic map from a high-dimensional stimulus space to a low-dimensional array of units. Because a topographic map preserves neighborhood relationships between the stimuli, the SOM can be applied to certain types of information processing such as data visualization. WebJul 6, 2024 · Here we can see a simple self-organizing map structure. We are having two input neurons, which essentially present features in our dataset. This also means that our input data can be represented by three-dimensional vectors. Above them, we can see so-called map neurons.
