11PT

Sinopsis

Description

1. Compute P-R values at each data point
2. devide range 0.0-1.0 on x-axis(recall) into 10 sub range (11 grid points)
3. Use the maximal precision value for each sub range as the precision for the corresponding left grid point
4. Do backward interpolation:
Precision(i) = max(Precision(i+1), Precision(i)) Xin
