Wasserstein距离也被称为推土机距离(Earth Mover’s Distance,EMD),用来表示两个分布的相似程度。Wasserstein距离衡量了把数据从分布 p p p移动成”分布 q q q时所需要移动的平均距离的最小值。Wasserstein距离是2000年IJCV期刊文章《The Earth Mover’s Distance as a Metric for Image Retrieval》提出的一种直方图...

The embedding is interpolated to the entire mesh by solving a biharmonic equation, and Euclidean distances in the em- bedding space provide a distance measure on the entire mesh. Since it is generally impossible to embed geodesic distances exactly into Euclidean space, this approach is likely to ...

Solution (Earthmover distance): Treat each sample set A corresponding to a “point” as a discrete probability distribution, so that each sample x∈A has probability mass px=1/|A|. The distance between A and B is the optional solution to the following linear program. Each x∈A corresponds...
如果是离散的分布,那就是每次移动一个有质量的点。(实际上Wasserstein距离就是在最优路径下搬运过程的最小消耗,又被称作Earth-Mover Distance)在一维分布时,很形象但在二维上面,事实上有很多种方法,推土机距离就是定义为穷举所有的方案,距离最小的那个正式定义...
Different from the previous methods that perform distance computation between the image-level em- beddings, our approach advocates the use of discriminative local information. We decompose an image into a set of local representations and use the optimal match...
