------------------------------------
Summary: Add support to read libSVM and SVMLight input files
Key: FLINK-1717
URL: https://issues.apache.org/jira/browse/FLINK-1717
Project: Flink
Issue Type: Improvement
Reporter: Till Rohrmann
In order to train SVMs, the machine learning library should be able to read
standard SVM input file formats. A widespread format is used by libSVM and
SMVLight which has the following format:
<line> .=. <target> <feature>:<value> <feature>:<value> ... <feature>:<value> #
<info>
<target> .=. +1 | -1 | 0 | <float>
<feature> .=. <integer> | "qid"
<value> .=. <float>
<info> .=. <string>
Details can be found [here|http://svmlight.joachims.org/] and
