$ how the score was worked out · NVIDIA DeepLearningExamples J… 32%
Each result implies a score on its own, after adjusting for how hard its test is and who ran it. The score is their weighted average, with a small pull toward the middle for thinly tested models. Each test's weight is its counts column above; here it's added up by who ran the tests. How it works
| source | results | share of the score |
|---|---|---|
 NVIDIA DeepLearningExamples Jasper and QuartzNet READMEs · lab-reported | 2 | 32% |
| prior · pull toward the middle | 68% | |
| weighted average | = 65.0 |
