To run:

1. Set 'file_path' and 'data_path' variables in 'crf_aggr_der.m'
2. Run 'crf_aggr_der.m'

Averaged over 5 folds NDCG and Precision results should be very close to those reported in 
Table 2 in [1]. Note that the folder also includes, parsed for Matlab, MQ2008-agg dataset 
from the LETOR4.0 data collection.
