Jensen-Shannon distance between phylogeniesE Lewitus
The Jensen-Shannon Distance (square root of the Jensen-Shannon Divergence) is a true metric distance with good statistical properties and biological interpretation. It's a kind of must in Biology, here just some examples: https://www.nature.com/articles/nature09944 http://compbio.mit.edu/cummeR...

数的Jensen-Shannon散度分析 distance、probability、distribution、entropy、uncertainty Jensen-Shannon散度是一种度量两个概率分布之间相似性的方法,它的界限是1(0 <= JSD(p,q) <= 1)。 我已经应用了Jensen-Shannon散度的python代码,我想分析我的结果。我不明白结果数字是什么意思。JSD(p,q)=1或JSD(p,q)=0是...

Therefore, essentially speaking, all improvements on TOPSIS method under the IF framework provide certain improvements on the order structure and the distance/similarity measures. Based on different IFDisMs, various forms of intuitionistic fuzzy TOPSIS (IF-TOPSIS) methods were developed and widely applied...
the hypergraph edit distance. This implies that our method possess the ability to distinguish hypergraphs under controlled structural-errors. 4.2 Real-World Datasets We compare our proposed Jensen-Shannon hypergraph kernel (JSHK) with several alternative state of the art structural characterization methods...
Prediction的精度,这一点让人(至少我是这样的)眼前一亮。 论文中不明白的地方:在loss函数中有两个点不是很清楚概念, Wasserstein distance和Kullback-Leibler...feature-map之间的像素之间的差距,用Kullback-Leiblerdivergence来度量 Pair-wise distillation:这个loss好像是来自其他论文的启发,直接拿来用了,看公式定义 ...
