Measured effects reported in the paper
| What was changed | Where | Measured | Effect |
|---|---|---|---|
| Restrict the PML subroutine to frequencies ≤ 18 and use empirical estimation for the rest | Entropy estimation on Zipf(1) · Zipf(1), 10^3 to 5*10^6 samples | speedup over raw PML: 0.824, 1.205, 1.669, 3.561, 4.852, 9.552, 13.337, 12.196 | Mixed |
| Use empirical estimation for frequencies above 18, reserving PML for frequencies ≤ 18 | Entropy estimation on Zipf(1) · Zipf(1), 10^3 to 5*10^6 samples | empirical-estimate fraction: 0.184, 0.317, 0.372, 0.505, 0.562, 0.695, 0.752, 0.886 | Helped |
| Use pseudo PML with empirical estimation on the easy-frequency region instead of applying raw PML throughout | Entropy estimation · Distributions with domain size N=10^5 | entropy estimation error | No clear effect |
