The result shows that the function which generates a Gabor frame by translations and modulations has "good" properties, i.e., it is sufficiently smooth and compactly supported.展开更多
In this paper, we give the dual processes for superprocesses in random environments constructed by L Mytnik and the comparison theorem of these superprocesses with Dawson-Watanabe superprocesses.

In order to understand student learning and make accurate predictions about studentperformance, this paper analyzed student performance under English teaching by using adecision tree algorithm, i.e. the C4.5 algorithm. The calculation process of the algorithm was simplifiedby the Taylor series, and an example was analyzed. The results showed that the runningtime of the improved C4.5 algorithm was improved by 22.86% compared with the C4.5 algorithm,the precision rate was above 75%, the recall rate was above 85%, and the F1-measure value wasabove 80%. The experimental results verified the effectiveness of the improved C4.5 method instudying student achievement. This work is beneficial to the further optimization of decision treealgorithms and provides some reference for the application of intelligent algorithms in the fieldof education.展开更多
