Ex. 8EM Algorithm and K-Means Algorithm

Aim: To apply EM algorithm to cluster a set of data stored in a .csv file. Use the same dataset for
clustering using k-means algorithm.

Code:
from sklearn.cluster import KMeans
from sklearn.mixture import GaussianMixture
import sklearn.metrics as metrics
import pandas as pd
import numpy as np
import matplotlib.pyplot as plt

names = ['Sepal_Length','Sepal_Width','Petal_Length','Petal_Width', 'Class']

dataset = pd.read_csv("8-dataset.csv", names=names)

X = dataset.iloc[:, :-1]

label = {'Iris-setosa': 0,'Iris-versicolor': 1, 'Iris-virginica': 2}

y = [label[c] for c in dataset.iloc[:, -1]]

plt.figure(figsize=(14,7))
colormap=np.array(['red','lime','black'])

# REAL PLOT
plt.subplot(1,3,1)
plt.title('Real')
plt.scatter(X.Petal_Length,X.Petal_Width,c=colormap[y])

# K-PLOT
model=KMeans(n_clusters=3, random_state=0).fit(X)
plt.subplot(1,3,2)
plt.title('KMeans')
plt.scatter(X.Petal_Length,X.Petal_Width,c=colormap[model.labels_])

print('The accuracy score of K-Mean: ',metrics.accuracy_score(y, model.labels_))
print('The Confusion matrixof K-Mean:n',metrics.confusion_matrix(y, model.labels_))

# GMM PLOT
gmm=GaussianMixture(n_components=3, random_state=0).fit(X)
y_cluster_gmm=gmm.predict(X)
plt.subplot(1,3,3)
plt.title('GMM Classification')
plt.scatter(X.Petal_Length,X.Petal_Width,c=colormap[y_cluster_gmm])

print('The accuracy score of EM: ',metrics.accuracy_score(y, y_cluster_gmm))
print('The Confusion matrix of EM:n ',metrics.confusion_matrix(y, y_cluster_gmm))

Output:
The accuracy score of K-Mean: 0.09333333333333334
The Confusion matrixof K-Mean:
[[ 0 50 0]
[ 2 0 48]
[36 0 14]]
The accuracy score of EM: 0.9666666666666667
The Confusion matrix of EM:
[[50 0 0]
[ 0 45 5]
[ 0 0 50]]

Go to settings/playback speed. Even funnier at 2X speed

Super।

I do wonder if the prank victims still watch these videos later on from time to time. Or ever watched afterwards. Shoot me a message by responding to this posting if you are one of them and tell me which =)

Very good!

I think when you are 30 you should take part in a seminar that you can report to the police if they drown dogs or drive drunk 😀
