Isye 6501 Final exam with complete solution 1. 1-norm: Similar to rectilinear distance; measures the straight-line length of a vector from the origin. If z=(z1,z2,...,zm) is a vector in an m-dimensional space, then it's 1-norm is square root(|5g1|+|5g2|+ï+|5g5Z| = |5m£g1o|+v|e5rgi2=|1+ï|+5|g55gV| |= 2. A/B Testing: testing two alternatives to see which one performs better 3. 2-norm: Similar to Euclidian distance; measures the straight-line length of a vector from the origin. If z=(z1,z2,...
