+  This report analyses distance metrics learning techniques with regards to 
+  identification accuracy for the dataset CUHK03. The baseline method used for 
+  identification is Eucdidian based Nearest Neighbors based on Euclidean distance. 
+  The improved approach we propose utilises Jaccardian metrics to rearrange the NN
+  ranklist based on reciprocal neighbours. While this approach is more complex and introduced new hyperparameter, significant accuracy improvements are observed -
+  approximately 10% increased Top-1 identifications, and good improvements for Top-$N$  accuracy with low $N$.

-# 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.

+The problem to solve is to create a ranklist for each image of the query set

+not be considered when forming the ranklist.
