Can we set the random seeds to initialize the SOM?

thanks! is it possible to set it from python?

xgdgsc commented 2 years ago

generate the initialcodebook by your seed and pass to the constructor?

yanzastro commented 2 years ago

sounds like a great idea! So I just run something like:

codebook_ini = init(data, seed)  # init() is a pre-defined function to initialize the codebook
som.codebook = codebook_ini
som.train(...)

is it correct?

---edit---

Oh I see there is a initialcodebook parameter. never mind!
