Source Code

```import pandas as pd import numpy as np from matplotlib import pyplot as plt from scipy.cluster.hierarchy import dendrogram, linkage """# Read original data with all coefficients We will read the original .csv file and then extract the desired column """ data = pd.read_csv('original_data.csv') # drop na data = data.dropna() data.head() """# Get data for column 'Degree = 4 Coefficients' The column contains the points in a string '[ .. ]', so we will have to parse that string to remove the brackets and extract the float values """ pointsraw = data['Degree=4 Coefficients'].to_numpy() # extract values and convert to numpy # Now, take each row, remove first and last characters ( [] ), and split X = np.zeros((pointsraw.shape[0], 5)) # Matrix to store all 39 samples # Loop through each raw sample for i, points_str in enumerate(pointsraw): points_str = points_str[1:-1] # remove first and last characters which are [] # Split points_lst = points_str.split() # Convert to float points_i = list(map(float, points_lst)) # Add to matrix X[i,:] = points_i """# Hierarchical Clustering""" Z = linkage(X, method = 'ward', metric = 'euclidean') """# Dendogram""" # Create figure plt.figure(figsize=(25, 15)) # Create dendogram dendrogram( Z, leaf_rotation=90., # rotates the x axis labels leaf_font_size=8., # font size for the x axis labels ) plt.title('Hierarchical Clustering Dendrogram', fontsize=25) plt.xlabel('Index', fontsize=25) plt.ylabel('Euclidean Distance', fontsize=25) plt.show() ```
