-# Summary
-In this report we analysed how distance metrics learning affects classification
-accuracy for the dataset CUHK03. The baseline method used for classification is
-Nearest Neighbors based on Euclidean distance. The improved approach we propose 
-mixes Jaccardian and Mahalanobis metrics to obtain a ranklist that takes into 
-account also the reciprocal neighbors. This approach is computationally more 
-complex, since the matrices representing distances are effectively calculated 
-twice. However it is possible to observe a significant accuracy improvement of 
-around 10% for the $@rank1$ case. Accuracy improves overall, especially for
-$@rankn$ cases with low n.
