One post tagged with "parsing"

This morning we published a post that ended with a tidy rule: some address tags don't want a neural network, they want a lookup table. Country names are a closed list in a known position. Our deterministic matcher scored a perfect 100 on the eval. The retrained model scored a mess. Case closed, we wrote.

By the afternoon we'd reopened the case, and the verdict flipped — hard enough that we've retracted the morning post rather than leave the wrong conclusion lying around for someone to cite. This is the story of how a perfect score nearly talked us out of the entire premise of the project.
