V-Net's Dice coefficient for soft predictions is D=2∑ipigi∑ipi2+∑igi2D = \frac{2\sum_i p_i g_i}{\sum_i p_i^2 + \sum_i g_i^2}. Four voxels have predicted foreground probabilities p=(0.9,0.8,0.3,0.1)p = (0.9, 0.8, 0.3, 0.1) and ground truth g=(1,1,0,0)g = (1, 1, 0, 0). What is DD?

a number between 0 and 1, 3 decimals
