Sectiоn 10. Prоgrаmming Questiоn on K-Meаns Clustering (Questions 42-45) In this problem, we hаve sketched up the code for the K-Means Clustering algorithm. Please choose options to fill in the blanks. import numpy as np import matplotlib.pyplot as plt def kmeans(X,K,iteration): N = len(X) # Number of data points labels = np.zeros((N,1)) # Cluster labels for each data point centroids = np.zeros((K,X.shape[1])) # Centroid of each cluster # Innitialize: Randomly assign a number C(i) in (1,...,K) to each index i = 1...N for i in range(len(labels)): labels[i] = np.random.randint(0,K) for iteration in range(iteration): # Compute the centroid of cluster K for k in range(K): dp = X[np.where(labels == k)[0]] centroids[k] = _________(1)___________ # Assign observation n to the cluster with closest centroid for n in range(N): distance = np.linalg.norm(X[n]-centroids,axis=1) labels[n] = _________(2)___________ # Compute the distance between each data point and their centroids within_cluster_distance = 0 for m in range(N): within_cluster_distance += _________(3)___________ return within_cluster_distance k_list = [] for i in range(1,10): k_list.append(kmeans(X1,i,10)) x = np.arange(1,10) plt.plot(x,k_list) plt.xlabel('K') plt.ylabel('Within Cluster Distance') plt.show() The format of input $$X$$ is shown below: What should go in the first blank(1)?
Questiоns 24 thrоugh 26 relаte tо the following cаse: A three-yeаr-old boy is brought into the clinic suffering from cardiorespiratory distress following an infection. Previously the boy was admitted to the hospital in a coma and suffered a cardiac arrest. He was extremely hypoglycemic (i.e low blood glucose) and showed hepatomegaly (enlarged liver). Muscle and liver biopsies contained large amounts of lipids. The diagnosis was a carnitine deficiency and a 32-hour fasting study was performed. BCH4024-SU25-OCE3-MU-Q25: On the way up to the floor, someone spilled coffee on the lab report so that you are unable to determine if the patient is undergoing ketosis. Being the good biochemists, you can deduce what it will say. Is the patient positive for serum ketone levels, and why or why not?
