> 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 [here|http://www.csie.ntu.edu.tw/~cjlin/libsvm/faq.html#/Q03:_Data_preparation]
