Measured effects reported in the paper
| What was changed | Where | Measured | Effect |
|---|---|---|---|
| Use hit-and-run moves over the zonotope instead of local basis-exchange moves | Projection DPP sampling · Complete graph K_{10} and BA(20,2) | mixing per iteration | Helped |
| Use hit-and-run moves over the zonotope instead of local basis-exchange moves | Projection DPP sampling · Complete graph K_{10} and BA(20,2) | mixing per wall-clock time: more than 10^6 iterations compared to roughly 50 000 steps | No clear effect |
| Use hit-and-run moves over the zonotope instead of local basis-exchange moves | Projection DPP sampling · Text summarization | different summaries explored: about 50% against 10% | Helped |
| Use hit-and-run moves over the zonotope instead of local basis-exchange moves | Projection DPP sampling · Text summarization | variance of estimates | Helped |
