It seems the next run will be influenced by the former run. Will it be more rational to reset after every run? about minisom

Hi there, not sure I get your question but if you want to be able to replicate your experiments, you need to set random seed to a specific value. The MiniSom constructor takes in it input as random_seed.

I set random_seed=None. I mean if I run minisom for 5 times (10 epochs every time), it should have output 5 similar results separately, but it actually output 5 results that seems like with accumulative weights. And the fifth result is more similar to the result run for 50 epochs.

What do you mean by accumulative weights? Have you checked the quantization error?

Sorry, I found it's not the issue of minisom, and it seems I should write the topology code
more suitable for my data.
