COLLABORATIVE COMPRESSION

摘要

Provided are, among other things, systems, methods and techniques for collaborative compression, in which is obtained (41) a collection of files (61-66), with individual ones of the files (61-66) including a set of ordered data elements (56-58) (e.g., bit positions), and with individual ones of the data elements (56-58) having different values in different ones of the files (61-66), but with the set of ordered data elements (56-58) being common across the files (61-66). The data elements (56-58) are partitioned (44) into an identified set of bins based on statistics for the values of the data elements (56-58) across the collection of files (61-66), and a received file (131) is compressed (47) based on the bins of data elements (56-58).
