Information-based uncertainty decomposition in dual-channel microwave remote sensing of soil moisture

Bonan Li, Stephen P. Good
2021 Hydrology and Earth System Sciences  
Loss of information in the DCA modeling process contributes 35 % of the unexplained information, while the remainder is induced by a lack of additional explanatory power within TBh, TBv, and Teff.  ...  The results show that, on average, 80 % of the information in the in situ soil moisture is unexplained by SMAP DCA soil moisture estimates.  ...  This project was supported by the National Aeronautics and Space Administration (NASA) under grant NNX16AN13G.

OB-PWS: Obfuscation-Based Private Web Search

Ero Balsa, Carmela Troncoso, Claudia Diaz
2012 2012 IEEE Symposium on Security and Privacy  
Based on these results, we elicit a set of features that must be taken into account when analyzing the security of OB-PWS designs to avoid falling into the same pitfalls as previous proposals.  ...  The basic privacy mechanism in OB-PWS is the automatic generation of dummy queries that are sent to the search engine along with users' real requests.  ...  From a query analysis perspective, the adversary can implement a DCA that exploits this feature, and identifies as Q R queries Q C that are associated with categories included in set C according to SCA  ...

Optimistic Robust Optimization With Applications To Machine Learning [article]

Matthew Norton and Akiko Takeda and Alexander Mafusalov
2017 arXiv   pre-print
In this paper, we explore an optimistic, or best-case view of uncertainty and show that it can be a fruitful approach. We show that these techniques can be used to address a wide variety of problems.  ...  Although many of the problems resulting from our approach are non-convex, we find that DCA or DCA-like optimization approaches can be intuitive and efficient.  ...  Acknowledgements This work was partially supported by the International Internship Support Program of the Institute of Statistical Mathematics, ROIS, and Grant-in-Aid for Scientific Research (C), 15K00031  ...
