Here k ← k + 1 means that we are assigning the value k + 1 to the variable k.
Homework Answers
By dividing q by norm of q, q is being normalized, and the normalized vector is now stored in x, and the while loop continues. So, this line is just to normalize the vector q

Using R,
Exercise 4 (CLT Simulation) For this exercise we will simulate from the exponential distribution. If a random variable X has an exponential distribution with rate parameter A, the pdf of X can be written for z 2 0 Also recall, (a) This exercise relies heavily on generating random observations. To make this reproducible we will set a seed for the randomization. Alter the following code to make birthday store your birthday in the format yyyymmdd. For example, William...

K-means clustering K-means clustering is a very well-known method of clustering unlabeled data. The simplicity of the process made it popular to data analysts. The task is to form clusters of similar data objects (points, properties etc.). When the dataset given is unlabeled, we try to make some conclusion about the data by forming clusters. Now, the number of clusters can be pre-determined and number of points can have any range. The main idea behind the process is finding nearest...
