Random forest code was written in Java for this study, and all statistical analyses (e.g., model performance estimates) were performed using R.
The method performs well in the analyzed datasets and, importantly, gives stable performance estimates across cross-validation as well as independent test set runs.
"The board has limited confidence in current performance estimates generated by the D.O.E.'s performance assessment model," the letter said.
Excluding those one-time charges, Sun -- which makes powerful computers for businesses -- broke even, slightly exceeding the performance estimates of Wall Street analysts.
Last month, the Nuclear Waste Technical Review Board, an independent body created by Congress, reported that "the technical basis for D.O.E.'s repository performance estimates is weak-to-moderate at this time".
The board said in a letter last week to the energy secretary and Congressional leaders that "the technical basis for the D.O.E.'s repository performance estimates is weak to moderate at this time".
The Nuclear Waste Technical Review Board, which Congress created specifically to look at storage problems, said last month that the "technical basis" for the Energy Department's performance estimates "is weak to moderate".
We also provide confidence intervals for our performance estimates.
That's not much of a surprise though, as Apple has historically tended to low-ball its quarterly performance estimates.
This work attempts to quantify the resulting difference between performance estimates based on these two assumptions.
We introduce the reader to several synchronization notions and performance estimates.
