Bayesian search theory - Definition, explanation Bayesian search theory is the application of Bayesian statistics to the search for lost objects. Construct a search path which starts at the point of highest probability and 'scans' over high probability areas, then intermediate probabilities, then the low probability areas. if you have searched location X then the probability that the vessel is there is greatly reduced and the probabilities of all other locations must be increased. www.calsky.com /lexikon/en/txt/b/ba/bayesian_search_theory.php   (315 words)

Search and rescue information - Search.com Search and rescue (acronym SAR) is an operation mounted by emergency services, often well-trained volunteers, to find someone believed to be in distress, lost, sick or injured either in a remote or difficult to access area, such as mountains, desert or forest ("Wilderness search and rescue"), or at sea, whether close to shore or not. A substantial body of mathematical theory called search theory, some initially developed for anti-submarine warfare, has been developed and can be used to help choose the search patterns for maritime search operations. Search is usually an iterative process over many hours or even days, with returning personnel interviewed or debriefed to glean information to be incorporated into plans for the next personnel deployment. domainhelp.search.com /reference/Search_and_rescue   (1635 words)

The Impending Social Search Inflection Point Search engines are trying to resolve user intent more than content connectivity, and social search adds a new relevance layer to information retrieval in the form of context, freshness and some understanding of personal significance, personalization. Search is the Internet OS connecting disjointed pieces of data hosted in totally different places and creating incremental knowledge value. Social search is not a substitute to traditional search... searchengineland.com /070403-040029.php   (2162 words)

Old-school theory is a new force | CNET News.com Search giant Google and Autonomy, a company that sells information retrieval tools, both employ Bayesian principles to provide likely (but technically never exact) results to data searches. Researchers are also using Bayesian models to determine correlations between specific symptoms and diseases, create personal robots, and develop artificially intelligent devices that "think" by doing what data and experience tell them to do. Bayesian theory can roughly be boiled down to one principle: To see the future, one must look at the past. news.com.com /2009-1001-984695.html   (2051 words)

The Bayesian Search Theory - The Fuselage Bayesian Search Theory is using statistics in the search for lost objects. if you have searched location X then the probability that the vessel is there is greatly reduced (though not usually zero) and the probabilities of all other locations must be increased. Danielle did state her purpose wasn't to come to the Island - but they must have gone there in the end for the reason, and I believe they thought the object they were looking for could have been there, but not the first searching place on the agenda. www.thefuselage.com /Threaded/showthread.php?t=28831   (775 words)

Prediction Sometimes one is interested in using a sample, or a database, to predict properties of a new sample, where it is assumed the two samples are obtained from the same probability distribution. , and an offshoot of the Bayesian learning method called constraint based causal discovery, which use the data to limit sometimes severely the possible causal models [11, 26, 24] While techniques in the first class are still not practical on very large data sets, a limited version of the. citeseer.ist.psu.edu /context/360164/0   (1851 words)

Decision Theory and Adaptive Systems - Home Areas of attention include automated reasoning and inference under uncertainty, data mining and knowledge discovery in databases, learning models from data,, information retrieval, automated diagnosis and decision support, and automated learning for custom-tailoring software to user work patterns and preferences. Explicit consideration of user preferences and key uncertainties associated with particular tasks and contexts is a central element of DTAS projects.
