  • Visual information retrieval system for applying self organizing maps/SOM using five distinct modules that merge the best maps
    Patent number: 8666898
    Abstract: A system for information retrieval within a database of large size includes a first module for extracting the descriptors associated with each object in the database, and for constructing a table containing the objects and the value of a descriptor associated with an object. The system also includes a second module for applying a number of classification algorithms, for each of the tables obtained from the module, a third module to fusion the results obtained from the module in order to determine, for each type of descriptor, a class number associated with an object, a fourth module for finding which column of a table is closest to the column obtained during the first fusion of the step, and for selecting the map that is closest contained in the table, or best map, and a fifth module to fusion the aggregate “best maps”, and applying an algorithm for searching for the best map to be transmitted to a display means.
