Jeffrey Uhlmann
{{short description|American research scientist}}
Jeffrey K. Uhlmann is an American research scientist who is probably best known for his mathematical generalizations of the Kalman filter.{{cite book |title=Handbook of Multisensor Data Fusion |editor1-first= Martin |editor1-last=Liggins |editor2-first=David |editor2-last=Hall |editor3-first=James |editor3-last=Llinas |chapter=Chapters 14 and 15 |publisher=CRC Press |edition=2 |year=2008}} Most of his publications and patents have been in the field of data fusion. He is also known for being a cult filmmaker and former recording artist.
Dr. Uhlmann is ranked in the top 2% among scientists worldwide in the Stanford University listing of most-cited researchers.{{cite journal |last1=Ioannidis |first1=John P.

Biography
Uhlmann has degrees in philosophy, computer science, and a doctorate in robotics from the University of Oxford.{{Cite web |url=http://people.cs.missouri.edu/~uhlmannj/Dissertation-pref.pdf |title=Archived copy |access-date=2011-10-18 |archive-url=https://web.archive.org/web/20120407061202/http://people.cs.missouri.edu/~uhlmannj/Dissertation-pref.pdf |archive-date=2012-04-07 |url-status=dead }}{{cite web |url=http://engineering.missouri.edu/person/uhlmannj/ |title=Uhlmann, Jeffrey {{!}} Engineering {{!}} University of Missouri {{!}} Mizzou Engineering |website=engineering.missouri.edu |url-status=dead |archive-url=https://web.archive.org/web/20120405044855/http://engineering.missouri.edu/person/uhlmannj/ |archive-date=2012-04-05}} He began work in 1987 at NRL's Laboratory for Computational Physics and Fluid Dynamics in Washington, DC, and remained at NRL until 2000. Since 2000 he has been a professor of computer science at the University of Missouri.{{Cite web |url=http://people.cs.missouri.edu/~uhlmannj/ |title=Archived copy |access-date=2011-10-18 |archive-url=https://web.archive.org/web/20120407061222/http://people.cs.missouri.edu/~uhlmannj/ |archive-date=2012-04-07 |url-status=dead }}
He served for ten years as a co-founding member of the editorial board of the ACM Journal of Experimental Algorithmics (1995–2006) before becoming co-editor of the Synthesis Lectures on Quantum Computing series for Morgan & Claypool.{{Cite web|url=http://www.morganclaypool.com/toc/qmc/1/1|title = Synthesis Lectures on Quantum Computing}}
Theoretical Research
Uhlmann published seminal papers on volumetric, spatial, and metric tree data structures and their applications for computer graphics, virtual reality, and multiple-target tracking.{{cite book |title= Foundations of Multidimensional and Metric Data Structures |author=Hanan Samet |publisher=Morgan Kaufmann |year=2006|author-link=Hanan Samet}}{{cite journal |author=Jeffrey Uhlmann |journal= Information Processing Letters |title=Satisfying General Proximity/Similarity Queries with Metric Trees |volume=40 |issue=4 |year=1991|doi=10.1016/0020-0190(91)90074-r |pages=175–179}}{{cite journal |author=Jeffrey Uhlmann |title=Algorithms for Multiple-Target Tracking |journal=American Scientist |volume=80 |issue=2 |year=1992|page=128 |bibcode=1992AmSci..80..128U }} He originated the unscented transform (and its use in the unscented Kalman filter) and the data fusion techniques of covariance intersection and covariance union.
His work in artificial intelligence has recently focused on tensor-completion methods for recommender system applications.{{cite journal |last1=Nguyen |first1=Tung |last2=Uhlmann |first2=Jeffrey |title=Tensor Completion with Provable Consistency and Fairness Guarantees for Recommender Systems |journal=ACM Trans.

Applied Results
Uhlmann's results are widely-applied in tracking, navigation, and control systems, including for the NASA Mars rover program.{{cite report|author=E.T. Baumgartner|title=State Estimation and Vehicle Localization for the FIDO Rover|publisher=NASA-JPL|year=2000|url=http://trs-new.jpl.nasa.gov/dspace/bitstream/2014/15997/1/00-1838.pdf|display-authors=etal|access-date=2011-10-18|archive-url=https://web.archive.org/web/20120415134042/http://trs-new.jpl.nasa.gov/dspace/bitstream/2014/15997/1/00-1838.pdf|archive-date=2012-04-15|url-status=dead}}{{cite conference |title=NASA Mars Rover: A Testbed for Evaluating Applications of Covariance Intersection |author=Jeffrey Uhlmann|book-title=Proceedings of the 1999 SPIE Conference on Unmanned Ground Vehicle Technology |volume=3693 |year=1999|display-authors=etal}} His results relating to the constrained shortest path problem and simultaneous localization and mapping are also used in rover and autonomous vehicle applications.{{cite journal |title=An Efficient Algorithm for Computing Least Cost Paths with Turn Constraints |author1=Ali Boroujerdi |author2=Jeffrey Uhlmann |journal=Information Processing Letters |year=1998|doi=10.1016/s0020-0190(98)00134-3 |volume=67 |issue=6 |pages=317–321}}{{cite journal |title=Using Covariance Intersection for SLAM |author1=S.

Films
Uhlmann has written, directed, produced, and/or acted in several prominent short and feature-length films. Notable examples include the animated short film Susan's Big Day{{cite web | title=Susan's Big Day |website = YouTube| date=8 September 2011 |url=https://www.youtube.com/watch?v=xJ6BhYHVVEg |access-date=2011-10-11}} and the feature films Mil Mascaras vs. the Aztec Mummy, Academy of Doom, and Aztec Revenge. In recent years he has been a popular invited guest at international genre film festivals.{{cite web |url=http://www.mmvsam.com/fantasia.htm |title=Fantasia International Film Festival |access-date=12 April 2009}}
Music
Uhlmann recorded and released a series of albums in the 1970s and 1980s. Some of his early experimental electronic albums have been reissued in their entirety on CD{{cite web |url=http://www.tower.com/wapi/116928985 |title=Impulse (CD) |publisher=Tower Records |access-date=10 October 2010}} or digital download{{cite web|url=http://www.vicmod.net/music/circuit%20theory/circuit%20theory.html |title=Circuit Theory |publisher=Vicmod Records |access-date=31 October 2011 |url-status=dead |archive-url=https://web.archive.org/web/20120425122401/http://www.vicmod.net/music/circuit%20theory/circuit%20theory.html |archive-date=2012-04-25 }} while his arguably better-known songs are only available on CD compilations.{{cite web |url=http://www.tower.com/wapi/116823025 |title=Performer (CD) |publisher=Tower Records |access-date=22 October 2011}}
