Abstract
A data processing device for selecting data words which are contained in a dictionary and which are nearest to a data word to be processed according to a correspondence criterion. The device includes: first apparatus for segmenting the space enclosing the assembly of data words of the dictionary; second apparatus for generating, for each segment, sub-dictionaries by making an arbitrary segment correspond, in accordance with the correspondence criterion, to words of a sub-dictionary; third apparatus for utilising the sub-dictionaries by determining, for an arbitrary data word to be processed, the segment with which it is associated, followed by determination, in accordance with the correspondence criterion, of that word or words among the words of the sub-dictionary associated with the segment which corresponds (correspond) best to the arbitrary data word to be processed. Segmentation can be realised by means of a layered or tree-like neural network. The device may be used for data compression or data classification.
