-The Discounted Cumulative Gain is a measure of ranking quality. 
-It is used to evaluate Information Retrieval Systems under the following 2 assumptions:
-1. Highly relevant documents/Labels are more useful when appearing earlier in the results
-2. Documents/Labels are relevant to different degrees  
+- ranking
 
-It is defined as the Sum over all relevances of the retrieved documents reduced logarithmically proportional to 
-the position in which they were retrieved.
-The Normalized DCG (nDCG) divides the resulting value by the optimal value, that can be achieved, to get a value between 
-0 and 1 s.t. a perfect retrieval achieves a nDCG of 1.
