至此可以很自然引入接下来的Optimal Transport Theorem!核心思路就是找到一个可以处理non-overlapping情况的probability measures! OT theory involved Optimal Transport OT可以刻画分布之间很自然的变化过程,进而能给出衡量各种分布类型之间距离的度量(定义研究对象的distance,OT自动给出研究对象分布的distance)。比如离散-离散...

感觉Optimal Transport Theory逐步成为近年热门的机器学习theoretical tool。其在ML中的应用也是很广泛,如一大类生成模型。其众多成功案例中,背后有OT来做支撑的如Wasserstein GAN。从理论分析出发,实现很小的改变就解决了原始GAN训练稳定性,collapse mode等问题。近来涉及到要使用相关理论,故将该工具分享给大家,若有谬误...
The OT theory is employed to quantify the difference between the distribution formed by the robot trajectories and the given reference spatial distribution indicating the priority. A computationally feasible way is developed to measure the performance of the proposed exploration scheme. Further, the ...

Understanding and improving Generative Adversarial Networks (GAN) using notions from Optimal Transport (OT) theory has been a successful area of study, originally established by the introduction of the Wasserstein GAN (WGAN). An increasing number of GANs incorporate OT for improving their discriminator...
Particularly, we developed CMOT (Cross-Modality Optimal Transport), a computational approach to infer missing modalities of single cells. CMOT first aligns the cells with multimodal data (source) if the cells do not have complete correspondence, and then applies OT to map the cells from single mo...
Variational problems that involve Wasserstein distances and more generally optimal transport (OT) theory are playing an increasingly important role in data sciences. Such problems can be used to form an examplar measure out of various probability measures, as in the Wasserstein barycenter problem, or ...

To achieve the global optimal assigning result under the one-to-many situation, we propose to formulate label as- signment as an Optimal Transport (OT) problem – a special form of Linear Programming (LP) in Optimization Theory. Specifically, we define each gt as a supplier who s...
