Is hyperopt avaiable for ensemble?

[Ball]

Hi all,

I am trying to assign weight to the backends included in a simple ensemble of omikuji-bonsai, mllm, and xtransformer. Can I use the hyperopt command to get the best settings? or it's a manual process to try different combinations?

Thanks,

Lucas

Hi Lucas,

Yes, you can use hyperopt for that with the (simple) ensemble.

Just noticed that the ensemble page in Annif wiki is missing this information, I'll add it.
