用法: skimage.measure.shannon_entropy(image, base=2)计算图像的香农熵。香农熵定义为 S = -sum(pk * log(pk)),其中 pk 是值为 k 的像素的频率/概率。参数: image:(N, M) ndarray 灰度输入图像。 base:浮点数,可选 要使用的对数底。 返回: entropy:浮点数 ...
交叉熵(Cross Entropy)是Shannon信息论中一个重要概念,主要用于度量两个概率分布间的差异性信息。若P(x)是数据的真实概率分布,q(x)是由数据计算得到的概率分布。机器学习的目的就是希望q(x)尽可能地逼近甚至等于P(x)。对q(x)的优化就等效于求交叉熵的最小值。另外,对交叉熵求最小值,也等效于求最大似然估...
and here another biocore/qiime#280 for qiime, but again there are no news about it since 2015. Scikit-bio got a shannon entropy already, skbio.diversity.alpha.shannon but I don't know how far is from the Jensen Shannon Distance. So I was wondering whether scikit-bio can take any advant...
Diversity Indices:Using two entropy indices, the Shannon Index and Simpson Index, we can measure how evenly diversity exists in your tree inventory. 10/20/30 rule:Urban foresters have long used the 10/20/30 benchmark to measure diversity. The rule suggests no more than 10% of an urban tre...

BDM builds on block entropy’s decomposition approach using algorithmic complexity methods to obtain and combine its building blocks. The result is a complexity measure that, as shown in Section 4.3, approaches K in the best case and behaves like entropy in the worst case (see Section 7.1), ...
