Suppose that you need to group some data into clusters, and you run K-means 100 times,starting each time from a different random initialisation. You get 100 different clusterings of thedata. Which one should you choose?Simply pick one at random.Choose the one that minimises the mean distance of points from the centroid of their allocated cluster.Label the clusters 1, 2, ...,Choose the clustering you get from the 100th run.k each time, and assign each point to the cluster it ends up in most often.

Suppose instead of dividing in half at each step, you divide into thirds, sort each third, and combine using a 3-way merge. What is the order of growth of the overall running time of this algorithm?
We are going to use K-means algorithm to cluster 6 data points from dataset D = {0, 1, 2, 3, 4, 2022} in R1 into 2 clusters. Before the first iteration, the cluster centers are randomly initialized at c1 = 0.235 and c2 = 1.984. Next, we simulate the first iteration (for part (a) and (b)) of K-means with manual computation. (a) Compute the cluster assignment for each of the 6 data points given, using the Euclidean distance. [5 pts] (b) Compute the updated cluster center c1 and c2. [5 pts] (c) How many iterations are needed to finish the K-means algorithm for this problem? [10 pts]
Draw the Weighted Quick Union object on 0 through 10, that results from the following connect calls. Do not use path compression. Note that if we connect two sets of equal weight, by convention we make the set whose root has a smaller number the parent of the other. We use the convention that if an element is the root of the set its array value is the weight of the set negated. connect (0, 1); connect (2, 3); connect (9, 5); connect (5, 7); connect (7, 1); connect (4, 2); 1); connect (3,
you will learn how to manually classify and cluster data based on a specific variable using R programming language. consists of retrieving data, classifying, plot a graph and interpretation of the outcomes. The dataset that are going to be used in this project is “mtcar” that is available in R studio. Methodology: Using the number of cylinders (cyl column) in mtcar dataset(below), classify cars as 4-, 6- or 8-cylinders car. For each class, give a color to the values that belong to that class. Then plot a graph for using “mpg” column as x-axis and “qsec” column as y-axis. Steps: Read the file using R programming language. Read values in column “cyl”. If x =8, then paint as red, if x =6, then paint as green, If x =4, then paint as blue. Plot the values of the columns mpg and qsec into an x&y graph. Plot painted values of “cyl” on the same graph. Finally, you have to add your interpretations of the results. This is very important!

Question 2: The game of "FastestPath" consists of a path (a 1-D array) with n positive integers to represent n cities in a path (except the first index which has always value 0). The aim of the game is to move from the source city (located at index 0) to destination (located at last index) in the shortest time. The value at each index shows the travel time to enter the city located in the corresponding index. Here is a sample path where there are 6 cities (n is 6): 0 5 90 7 61 12 Always start the game from the first city and there are two types of moves. You can either move to the adjacent city or jump over the adjacent city to land two cities over. The total travel time of a game is the sum of the travel times of the visited cities. In the path shown above, there are several ways to get to the end. Starting in the first city, our time so far is 0. We could travel to city 2, then travel to city 4, then travel to last city for a total travel time of 90 + 61 + 12 = 163. However, a…
