Synthesizing human and machine capabilities
summary
Claim: stitching machines and humans yields better recommendations than either alone. The system runs PCA and SVD plus matrix factorization and neural nets on AWS to score inventory, then routes candidates through a queue to ~3,000 human stylists who curate five items; logistics picks, packs and ships. Controlled A/B tests and metrics like mean reciprocal rank measure machine-to-human matching. Outcome: machines prune millions of calculations quickly, humans add context, empathy and higher retention on difficult requests, producing additive performance and measurable lift.
