why use l_1 vs. l_2 data why use l_1 is l.1 metric good which metric is used best for clustering? what is the distance metric? why is l.1 more preferable when analyzing distance metrics which one is better? what is the best distance metric available which metric is better to use instead of l_1? which metrics are better distance or elliptical is l_.5 the most preferable measurement for data mining what distance is better $l_1 or $l_2 which distance metric is the best for clustering what is the optimal measure of distance how to find exponential distance why use l1 metrics why use l_1 instead of l_2 why are exponential metric useful what metrics do you use to analyze l1 which distance metric is best
