Geolocation-Prediction

My University of Ottawa thesis, rebuilt

Predicting where Canadian Twitter users live from what they tweet and who they follow. Revisiting my thesis code, I found and fixed seven bugs, including one that made every social-graph feature identical, then re-ran everything under stricter evaluation.

## highlights

Social graph: a vote over friends' and followers' locations places 88% of users within 161 km
Text: 61% within 161 km and a 42 km median error, up from 46% for the best 2019 model
Showed two 2019 models never learned anything; they predicted Toronto for everyone
