Is this overfitting?

[–] marcos@lemmy.world 53 points 7 months ago (3 children)

No, this is because the testing set can be derived from the training set.

Overfitting alone can't get you to 1.

So as an eli5, that's basically that you have to "ask" it stuff it has never heard before? AI has come after my time in higher education.

[–] marcos@lemmy.world 20 points 7 months ago (2 children)

Yes.

You train it on some data, and ask it about different data. Otherwise it just hard-codes the answers.

They're just like us.

[–] victorz@lemmy.world 1 points 7 months ago

Gotcha, thank you!

[–] ArtVandelay@lemmy.world 3 points 7 months ago

Yes, it's called a train test split, and is often 80/20 or there about

[–] sevenapples@lemmygrad.ml 3 points 7 months ago

It can if you don't do a train-test split.

But even if you consider the training set only, having zero loss is definitely a bad sign.
