Measured effects reported in the paper
| What was changed | Where | Measured | Effect |
|---|---|---|---|
| STELLAR vs FPMC-LR | successive POI recommendation · Foursquare | R@5: 0.347 -> 0.425 | Helped |
| STELLAR vs FPMC-LR | successive POI recommendation · Gowalla | R@5: 0.167 -> 0.226 | Helped |
| add POI-POI interaction to time-aware model (TLAR -> STELLAR) (ablation) | STELLAR · Foursquare | R@5: 0.373 -> 0.425 | Helped |
| add time-POI interaction (SLAR -> STELLAR) (ablation) | STELLAR · Foursquare | R@5: 0.368 -> 0.425 | Helped |
| add day-session slice to time index (ablation) | STELLAR · Foursquare | R@5: 0.371 -> 0.425 | Helped |
