Isye 6501 Final exam with complete solution 2023 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=(z...

ISYE 6501 FINAL EXAM WITH COMPLETE SOLUTION 2022/2023 1. Factor Based Models: classification, clustering, regression. Implicitly assumed that we have a lot of factors in the final model 2. Why limit number of factors in a model? 2 reasons: overfitting: when # of factors is close to or larger than # of data points. Model may fit too closely to random effects simplicity: simple models are usually better 3. Classical variable selection approaches: 1. Forward selection 2. Backwards eli...
