- Please answer it asap. both questions.arrow_forwardClassify the 1’s, 2’s, 3’s for the zip code data in R. (a) Use the k-nearest neighbor classification with k = 1, 3, 5, 7, 15. Report both the training and test errors for each choice. (b) Implement the LDA method and report its training and testing errors. Note: Before carrying out the LDA analysis, consider deleting variable 16 first from the data, since it takes constant values and may cause the singularity of the covariance matrix. In general, a constant variable does not have a discriminating power to separate two classes.arrow_forwardPlease answer question.arrow_forward
- Solve the recurrence relations shown below. a. T(n)={4T(n−1)+1if n>11if n=1T(n)={4T(n−1)+1if n>11if n=1 -- b. T(n)={3T(n/3)+4nif n>11if n=1arrow_forwardLogistic regression aims to train the parameters from the training set D = {(x(i),y(i)), i 1,2,...,m, y ¤ {0,1}} so that the hypothesis function h(x) = g(0¹ x) 1 (here g(z) is the logistic or sigmod function g(z) can predict the probability of a 1+ e-z new instance x being labeled as 1. Please derive the following stochastic gradient ascent update rule for a logistic regression problem. 0j = 0j + a(y(¹) — hz(x)))x; ave. =arrow_forwardUse & for •, v for V, > for Ɔ, and = for = What can you derive by applying De Morgan's (DM) to this formula: ~(N • E) Ɔ G (N v E) > G O (-N v -E) > G O (N & E) v G O (N & E) v G O (N v E) > G O (N & E) > Garrow_forward
- Consider the following recurrence relation: T(0) = 2, T(1) = 5, T(n) = 27(n – 1) – T(n – 2) for n>1 Write out the first few values T(0), T(1), T(2),...,. Make a guess about the closed form of T(n) and then prove that it is a closed form for T(n) using induction.arrow_forward1(a). For an M/M/1 queuing system, write your own function in R to compute andoutput the:1. long-run probability po,p1,…,pn of there being 0,..,n people in the system.2. the values L, Lq, W, Wq, and Wse. The function should return elements with the names probs (vector of po,…,pn), L, Lq, W,Wq, and Wse (does not have to be in this order) The function should take as inputs, lambda (arrival rate), mu (service rate), and n (thenumber of people to compute probabilities for 0,…,n) Note: you are to code the computations for the above on your own, so none of the functionsin the queueing package are to be used. 1(b). Using your function from 1(a), find the values (b)-(f) in the Queuing Theory(M_M_1).arrow_forward8. Solve the following recurrence relations. (16 points) a. T(n) = 4T(n-1) + 1 for n > 1; T(1) = 1; b. T(n) = T(n/2) + 3; T(1) = 1; Here you can assume that n=2k for some integer k.arrow_forward
