# Self-organizing maps: fuzzy input?

as my first post I would like to know if there are SOM implementations (preferably R) available that accept fuzzy input. That is, I have data in which some nominal features are spread out between a number of categories. For example: feature 1 has 5 categories and an observation might have the values (which are actually probabilities) [0, 0.5, 0.25, 0.25, 0].

Thanks, Figaro

Why wouldn't you just treat the 5 categories as 5 separate features? –  naught101 Dec 2 at 6:00
This does sound as a good and simple option, thank you. Is this good/best practice? I suppose there is no real way of avoiding the increased number of inputs? I ask because my sample size is quite small. –  Figaro Dec 2 at 8:42
