查询词典 rate

On the basis of these treatments, the patients in the treatment group also had aerobic kinesitherapy through limb and trunk exercises with assistance to improve oxygen consumption of the body and increase the heart rate. In each session of exercise, the patients were supposed to attain the target heart rate of 70％ to 85％ of the personal highest safe heart rate.At the beginning, each session of exercise lasted for 10-15 minutes and the heart rate or pulse was measured every 4-6 minutes, with the patients'heart rate allowed to increase by no more than 20/minute and the patients not feeling tired. The subsequent exercise time gradually increased but not over 30-40 minutes, twice a day for no less than 5 days a week.

In the traditional AdaBoost method,the weights are updated based on the weak classifier's overall error rate, this article proposes one kind of the method which unifies the level of difference between the threshold and the feature value of the weak classifier with the weak classifier's overall error rate. Compared to the method which only based on the overall classification error rate to update the weights,this method can achieve higher detection rate while reduces the mistaken-detection rate.

在传统AdaBoost方法中，权重是根据弱分类器的整体错误率来更新的，本文提出了一种将弱分类器的阈值与特征值相差程度和弱分类器的整体错误率相结合来更新样本权重的方法，相比较只根据整体分类错误率来进行权重更新的方法，这种方法可以在降低误检率的同时达到较高的检测率。
