SPatchGAN: A Statistical Feature Based Discriminator for Unsupervised Image-to-Image Translation [article]

Xuning Shao, Weidong Zhang
2021 arXiv   pre-print
The network is stabilized by distribution matching of key statistical features at multiple scales.  ...  For unsupervised image-to-image translation, we propose a discriminator architecture which focuses on the statistical features instead of individual patches.  ...  Analysis of Statistical Feature Matching Our discriminator is designed to match the statistical features of the generated images with the real images.  ...

Stratified Dense Matching for Stereopsis in Complex Scenes

J. Kostkova, R. Sara
2003 Procedings of the British Machine Vision Conference 2003  
Local joint image modeling in stereo matching brings more discriminable and stable matching features.  ...  The window adapts to high-correlation structures in disparity space found in pre-matching which is then followed by final matching.  ...  We claim that in order to produce good results it is essential to assign the matching over jointly discriminable and stable matching features.  ...

Sletto (1086) showed that a population of at least 400 is necessary to determine stable item-discrimination values, and that items which are highly discriminative in one group may be non-discriminative  ...  Jellinek (1055) deplored the misuse of statistics by psychologists and psychiatrists, and reiterated the point that even good statistics do not improve bad data.  ...

A statistical appraisal of disproportional versus proportional microbial source tracking libraries

Brian J. Robinson, Kerry J. Ritter, R. D. Ellender
2007 Journal of Water and Health  
The success of the library-based approach depends on how well each source candidate is represented in the library and which statistical algorithm or matching criterion is used to match unknowns.  ...  We examined prediction bias for four of the most commonly used statistical matching algorithms in library-based MST when applied to disproportionately-represented known source libraries; maximum similarity  ...  ACKNOWLEDGEMENTS The original data set used in this research was generated in 2003 through funding by The National Oceanic and Atmospheric Administration through the Coastal Impact  ...

Stable Distribution Alignment Using the Dual of the Adversarial Distance [article]

Ben Usman, Kate Saenko, Brian Kulis
2018 arXiv   pre-print
Our empirical results suggest that using the dual formulation for the restricted family of linear discriminators results in a more stable convergence to a desirable solution when compared with the performance  ...  In both cases, the dual formulation yields an iterative procedure that gives more stable and monotonic improvement over time.  ...  Adversarial methods seek to match the generated and real distributions by minimizing some notion of statistical distance between the two, which is often defined as a maximal difference between values of  ...
