Operating system (OS) noise refers to the interference experienced by an application due to activities inside an operating system. OS noise can significantly hurt the performance of applications, especially parallel applications. We implemented a tool, noise test, to study the characteristics of OS noise on the Godson-3A shared-memory multicore platform running Linux. We found that OS noise was balanced...
In order to quickly and exactly extract the subpixel image edge, a new method of subpixel image edge based on Fourier-Mellin moment is proposed. Firstly all possible edge points were detected quickly with using Fourier-Mellin moment operator with mask size of 3×3, secondly a Fourier-Mellin moment operator with mask size of 7×7 was used to relocate the edge with subpixel accuracy. Experiment results...
Ensemble classification methods have shown promise for achieving higher classification accuracy for microarray data classification analysis. As noise values do exist in all microarray data even after microarray data preprocessing stage, robustness is therefore another very important criteria in addition to accuracy for evaluating reliable microarray classification algorithms. In this paper, we conduct...
