Is there a way to obtain a distance of each point to its BMU?

[JMiklaszewski]

Hi, first and foremost thank you for your great work and allowing to implement SOM algorithm in such convienent way.
I wanted to ask if there is a possibility to obtain a kind of list with the distances between each point and its Best Matching Unit (Node) on trained SOM grid? I have read the documentation and saw different attributes for the SOM object, however it appears to me that none of them allow to return the (euclidean) distance to BMU. Thanks in advance for support!

hi there,

you can do compute the distance from the BMU as follows for a given samples as follows

1. pick the coordinates of the BUM using the method winner
2. retrieve the weights with get_weights and isolate the weights of the BMU
3. compute the distance between your sample and the weights of the BMU
