  • Distributed coding and prediction by use of contexts
    Patent number: 5652581
    Abstract: The present invention comprises a distributed data processing system including a plurality of data processing elements for expeditiously performing an encoding or prediction function pursuant to a context-based model in an adaptive, optimal and time-progressive manner. The distributed data processing system, having access to each symbol of an input data string at each clock cycle, adaptively generates context-relevant data sets which provide the best model for coding or prediction based on the input symbols. Each symbol and its best model for encoding or prediction emerge concurrently from the system, resulting in a favorable time complexity of .omicron.(n) for an n-symbol input data string.
    Type: Grant
    Filed: July 31, 1996
    Date of Patent: July 29, 1997
    Assignee: International Business Machines Corporation
    Inventors: Gilbert Furlan, Jorma Johannes Rissanen, Dafna Sheinvald
