ATOMSALGORITHMSSUCCESSIn order to further improve the success rate and accuracy of reconstruction of the compressed sensing reconstruction algorithm, a weak-selection backtracking matching pursuit based on Dice coefficient ( DWBMP) algorithm is proposed from the perspective of atomic match...
The statistical analysis of the fracture intensity suggests a strong negative linear correlation with the distance from the fault (R2 = 0.84–0.86), with a slope coefficient of −0.27 and −0.39 and a constant intercept of 8.29 and 9.22 for P21 and P32, respectively. Notwithstanding, due ...
#Python多类别Dice系数的应用 ## 引言 在深度学习领域,我们经常面临图像分割等任务,其中需要对每个像素进行分类。这种场景下,使用常规的准确率评估指标可能不足以反映模型的性能。因此,引入了Dice系数这一指标,尤其是在多类别分类问题中。 ## 什么是Dice系数?Dice系数(DiceCoefficient)是一个测量两个样本相似度的统计...
