Task Z (partner 1) On the basis of the baseline results produced in Task 1, determine the sequence in which the features should be used to build the hash filter . Justify your choice of feature sequence in the design of the hash lter. Determine the cost of each classication error at the leaves of the hash filter hierarchy tree . The error cost function (loss) is unique to this application .For each sample that is in error use the ground truth value (actual triple for Age, Gender and Race) and then determine the number of buckets to be searched to reach the target bucket according to the search procedure outlined above for the binary tree (siblings rst then parent , etc). The number of buckets to be searched is the cost for that sample .The overall loss is then the sum of all loss values for samples that are misclassified 2.1 Justify your choice of feature sequence in the design of the hash lter
