Provide MapReduce job for creating Encoded Vectors from sequence files

        Details

        • Type: Improvement
        • Status: Closed
        • Priority: Major
        • Resolution: Fixed

        • Component/s: None

          Description

          Similar to SparseVectorsFromSequenceFiles, provide a version that can do encoded vectors. Start simple by handling basic text, but this could easily evolve to handle pluggable Vectorizer's that can better deal with features (numerics, etc.).

              Patch that does basic work. Also refactors AbstractJob and HadoopUtil a bit to make it easier to use PrepareJob

              Progress. Extracted a Vectorizer interface, made the encoder pluggable, various other goodness.

              Also started to flesh out hooking in seq2encoded to build-asf-email so as to run SGD over the ASF email archive. Now just need train test per MAHOUT-851.

              Starts the conversion of DictionaryVectorizer. I now think we could fold SparseVectorsFromSequenceFiles and EncodedVectorsFromSequenceFiles, perhaps, into one class, if we use appropriate command line grouping of options.

              I've checked in some baseline functionality here. Going to leave this open, as I think we can really take this to an interesting level of capabilities.
