Hi!
I'm trying to train a pretty simple neural network, but no matter what I do, I always get the same results/prediction.
I don't know what I'm doing wrong, I've tried every configuration possible...
I don't know enough jsfiddle to setup one quickly, but here's a simplification of my code.
And as you'll see, the results are always the same, whatever the input.
I guess 0, it's probably a misuse
Is it a configuration issue? Or rather the format of data?
Thanks for your help!
Node v18.12.1
"brain.js": "^2.0.0-beta.23"
I tried to normalize the Input (related to https://github.com/BrainJS/brain.js/issues/712) My issue probably come from this, because, I now get different results, very similar but different.
What is wrong?

How do we replicate the issue?

I guess 0, it's probably a misuse
Is it a configuration issue? Or rather the format of data?
Thanks for your help!
