Measured effects reported in the paper
| What was changed | Where | Measured | Effect |
|---|---|---|---|
| Replace EMM with GMM (20 moment conditions) for learning the mixture of two Plackett-Luce models | 2-PL learning · Synthetic m=4, k=2, n up to 2000 | running time | Helped |
| Replace EMM with GMM for learning the mixture of two Plackett-Luce models | 2-PL learning · Synthetic m=4, k=2, n up to 2000 | MSE | No clear effect |
| Use 20 moment conditions instead of fewer in GMM (ablation) | GMM for 2-PL · Synthetic m=4, k=2 | MSE | Helped |
