Frog Problem 165

Simple little model, nothing too grand,

frog comes in, put a label on the man.

FROG CLASSIFIER (classifier-fier-fier)

Croak come in, prediction come out.

FROG CLASSIFIER

Ninety-eight percent — still got doubt.

Not a lake, not a lot,

just a little training batch.

Green frog, brown frog,

frog in the rain,

same frog twice but the labels ain't the same.

"Binary problem."

"Seventeen classes." (is that a toad?)

Precision nice,

recall look clean, then a new little frog turns up bright green.

Training loss dropping, confidence high,

frog on a log says the model tell lies.

We trained the machine to recognise the frog.

But nobody defined... frog.
