Adata scientist makes his argument for using trees and random forests: “trees and random forests are superior to machine learning methods, such as support vector machines and neural networks, because trees are unaffected by monotonic transformations of the explanatory variables.” how would you go about testing the transformation-invariance argument (with python and scikit-learn, for example) ?

When determining the classification of data, which one of the following is the most important consideration? a. processing systemb. valuec. storage mediad. accessibility

The following function returns a string of length n whose characters are all 'x'. give the order of growth (as a function of n) of the running time. recall that concatenating two strings in java takes time proportional to the sum of their lengths. public static string f(int n) { if (n == 0) return ""; if (n == 1) return "x"; return f(n/2) + f(n - n/2); } options: a) constant b) logarithmic c) linear d) linearithmic e)quadratic f)cubic g) exponential
