WebMay 17, 2015 · 获得一个矩阵,不同于信息检索的是F-Measure有多个,并且人工标记簇的个数和聚类算法得到的簇个数不一定相等。 若已人工标记的簇 ${{P}_{j}}$ 为基准,则聚类算法结果越接近人工标记的结果效果越好。 WebMar 24, 2024 · L^2-Space. On a measure space , the set of square integrable L2-functions is an -space. Taken together with the L2-inner product with respect to a measure , the -space forms a Hilbert space. The functions in an -space satisfy. The inequality ( 7) is called Schwarz's inequality . The basic example is when with Lebesgue measure. WebMar 30, 2024 · The new quality measure displays several desirable characteristics like symmetry w.r.t. prediction/ground truth pairs and balanced responsiveness across scales, which makes it more suitable for segmentation evaluation than other boundary-focused measures like Trimap IoU and F-measure.
