CSE 4502/5717 Big Data Analytics Fall 2020 Exam 3 Helpsheet 1. Let f : Rn → R be any function on n variables. Given a series of examples to learn f, we can fit them using a linear model: f(x1,x2,…,xn)=w1x1+w2x2+···+wnxn. Linearregressioncomputestheoptimalvaluesfortheparameters by equating the gradient to zero. Let the examples be (x1i ,x2i ,…,xni ;yi)

CS 112: Data Structures Sesh Venugopal Quicksort Algorithm Divide and Conquer Mergesort and Quicksort both use what’s called a “divide and conquer” technique In Mergesort, the “divide” step is trivial – just divide the array in two halves. All the work is done in “combine”, where sorted subarrays are merged Sesh Venugopal CS 112: Quicksort
