Transport-based analysis, modeling, and learning from signal and data distributions
This is an incremental review paper summarizing existing methods and their applications in various domains.
The paper provides an overview of transport-based techniques for analyzing and modeling signal and data distributions, highlighting their applications in areas like content-based retrieval and cancer detection, and noting that they have achieved state-of-the-art results in several applications.
Transport-based techniques for signal and data analysis have received increased attention recently. Given their abilities to provide accurate generative models for signal intensities and other data distributions, they have been used in a variety of applications including content-based retrieval, cancer detection, image super-resolution, and statistical machine learning, to name a few, and shown to produce state of the art in several applications. Moreover, the geometric characteristics of transport-related metrics have inspired new kinds of algorithms for interpreting the meaning of data distributions. Here we provide an overview of the mathematical underpinnings of mass transport-related methods, including numerical implementation, as well as a review, with demonstrations, of several applications.
