Subject [GitHub] incubator-hivemall issue #51: [HIVEMALL-75] Support Sparse Vector Format as ...
Date Fri, 03 Mar 2017 12:09:06 GMT
Github user myui commented on the issue:
    To reduce memory consumption, I'm considering to replace `int[][] order` with `CompressedIntStream[]`.
    `CompressedIntStream` should support streaming construction and should support streaming
decompression in
    Any good algorithm or library for fast integer sequence compression/decompression?
