Change in precision calculation #1

Closed abellogin closed 10 years ago

abellogin commented 10 years ago

Added a flag to not give too much advantage to recommenders with low coverage (if the flag is 1, then precision@k is normalised by k always).

Thanks @abellogin, fixed in release-0.2.2, with default behaviour now being to normalize by k and assume that all missing recommendations were incorrect.
