Translating feed-forward nets to SOM-like maps

Abstract
A major disadvantage of feedforward neural

networks is still the difficulty to gain insight into their internal functionality. This is much less the case for, e.g., nets that are trained unsupervised, such as Kohonen’s self-organizing feature maps (SOMs). These offer a direct view into the stored knowledge, as their internal knowledge is stored in the same format as the input data that was used for training or is used for evaluation. This paper discusses a mathematical

transformation of a feed-forward network into a SOMlike

structure such that its internal knowledge can be visually

interpreted. This is particularly applicable to networks

trained in the general classification problem domain.
