I don't understand why the height and weight errors aren't 0 when they are known inputs? If I say how tall I am, why is the model estimating something else?

That's a common phenomenon in model fitting, depending on the type of model. In both old school regression and neural networks, the fitted model does not distinguish between specific training examples and other inputs. So specific input-output pairs from the training data don't get special privilege. In fact it's often a good thing that models don't just memorize inputt-output pairs from training, because that allows them to smooth over uncaptured sources of variation such as people all being slightly different as well as measurement error.

In this case they had to customize the model fitting to try to get the error closer to zero specifically on those attributes.

This is the best UI/UX article I've read this year. If the authors are around, I extend them my dearest congratulations ^^.

Like ... who/why would downvote this? This is definitely manipulated.

My guess, the article itself is clearly AI authored and there are a fair number of us who don't particularly like the writing style. Further, it implies something about the original human's own valuation of this work - if they decided to let the machine handle it, why should I spend my own time reading what they didn't bother to write?
