-# Formulation of the Addresssed Machine Learning Problem

+# 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
-by finding the nearest neighbor(s) within a gallery set. However gallery images
-with the same label and taken from the same camera as the query image should
-not be considered when forming the ranklist.
