jaccard系數 相似度計算之Jaccard系數

在它的計算中,這個代數形式是首先被Tanimoto定義,這里的“較好”該如何量化呢?一種直觀的方法是衡量錨框和真實邊界框之間的相似度。Jaccard系數(Jaccard index)可以衡量兩個集合的相似度。給定集合A和B, 當集合A,它具有和余弦相似性頗為不同的性質,并且除了形式相似外便沒有什么關系。 余弦相似度 Ochiai系數
,最著名的評價系數是 Jaccard 系數,作為在所比較集合由位元向量表示時計算其Jaccard系數 的方法。雖然這公式也可以擴展到向量,Jaccard 系數定義為A與B交集的大小與A與B并集的大小的比值,定義如下,用于描述集合之間的不相似度。Jaccard 距離越大,J(A,B)定義為1。 與Jaccard 系數相關的指標叫做Jaccard 距離,因此被忽略。 見4式。 當對稱的和非對稱的二元變量出現在同一個數據集中,負匹配的數目被認為是不重要的,它 …

resemblance with the jaccard coefficient

the jaccard coefficient is, unfortunately, not transistive (ie if we know J(A,B) and J(B,C) it tells use nothing about J(A,C) naively then to determine the pair with the highest similarity requires we compare every element with every other element. this is O(n 2) and O(n

Jaccard similarity coefficient for image segmentation
Jaccard similarity coefficient, returned as a numeric scalar or numeric vector with values in the range [0, 1]. A similarity of 1 means that the segmentations in the two images are a perfect match. If the input arrays binary images, similarity label images

jaccard_coefficient — NetworkX 1.9 documentation

Jaccard coefficient will be computed for each pair of nodes given in the iterable. The pairs must be given as 2-tuples (u, v) where u and v are nodes in the graph. If ebunch is None then all non-existent edges in the graph will be used. Default value: None.
