we propose the active label distribution learning via kernel maximum mean discrepancy(ALDL-kMMD) method to tackle this crucial but rarely studied problem.ALDL-kMMD captures the structural information of both data and label,extracts the most representative instances from the unlabeled ones by ...

Ref[3]最后和MMD的关系也很有意思,值得过一段时间认真研究下(see also "Maximum Mean Discrepancy Gradient Flow")【话说MMD是non-parametric inference里比较常用的distance,在选test fn是Lipschitz时和W1-dist有关,Paul Dupuis有用它和KL mix起来设计新的distance的文章,更general的dist和flow在“KALE Flow: A ...
is called h -maximum mean discrepancy (mmd), see [ 16 ]. moreover, it can be shown that having a bounded and measurable kernel is also necessary for the mmd to be defined for all probability measures on \((x,\mathcal{a})\) , see e.g. [ 36 , prop. 2] in combination with ...
KCSD: The Kernel Conditional Stein Discrepancy (KCSD) established by Jitkrittum et al. (2020), evaluates conditional density models using a kernel-based approach, facilitating a reliable assessment of model fit. MMD: This method, adapting the Maximum Mean Discrepancy (MMD) (Gretton et al., 20...
这种散度统计量D称为最大*均差(maximum mean discrepancy,MMD)[42]。当MMD很大时,这表明两个点过程是不同的。在经典的假设检验框架中,我们需要假设两个集合来源于同一个潜在随机过程的零假设下的MMD分布。我们可以从零分布中产生MMD值,方法是将两个条件中的样本混合并从混合中重新采样[24, 42]。下面的简单...
Instead of using the classical Maximum Mean Discrepancy (MMD) technique, the K-CUSUM and K-DCUSUM methods use a non-parametric MMD testing framework to evaluate incoming data by comparing it to reference distribution samples. Further, a comprehensive analysis is undertaken on an LVDC test system,...

this end we define the mean elements µ[P](.) = E X∼P k(X, .), which are vec- tors obtained by averaging all k(X, .) over the probability distribution P. Gretton et al. [6] now introduced the Maximum Mean Discrepancy (MMD) between two probability measures P and Q, whi...
To this end, a Kernel Adaptive Filter (KAF) algorithm extracts the dynamic of each channel, relying on the similarity between multiple realizations through the Maximum Mean Discrepancy (MMD) criterion. To assemble dynamics extracted from all MoCap data, center kernel alignment (CKA) is used to ...
