666,000 addresses and not one country
· 5 min read
A month ago I wrote up the night I taught the geocoder Canada and it put Toronto in Ohio — 843,000 perfect postcodes that never got a vote, because the layer I'd built wasn't the layer that shipped. This is the sequel, and it rhymes. Last night I taught the parser three new countries. Two of them worked. The third one tripped a guard I trusted, and when I pulled the thread, the addresses turned out to be teaching the model something I never wrote into them.
