Practical Implementation with Code Examples

Here are some practical examples of how these algorithms can be implemented using Python and Linux commands:

1. Naive Bayes for Spam Detection

from sklearn.naive_bayes import MultinomialNB 
from sklearn.feature_extraction.text import CountVectorizer 
from sklearn.model_selection import train_test_split

<h1>Sample dataset</h1>

emails = ["Free money!!!", "Hi, how are you?", "Win a prize", "Meeting at 5 PM"] 
labels = [1, 0, 1, 0] # 1 = spam, 0 = not spam

<h1>Vectorize text data</h1>

vectorizer = CountVectorizer() 
X = vectorizer.fit_transform(emails)

<h1>Train-test split</h1>

X_train, X_test, y_train, y_test = train_test_split(X, labels, test_size=0.25)

<h1>Train Naive Bayes model</h1>

model = MultinomialNB() 
model.fit(X_train, y_train)

<h1>Predict</h1>

print(model.predict(X_test))

2. K-Means Clustering for Customer Segmentation

from sklearn.cluster import KMeans 
import numpy as np

<h1>Sample customer data</h1>

data = np.array([[1, 2], [1, 4], [1, 0], [10, 2], [10, 4], [10, 0]])

<h1>K-Means clustering</h1>

kmeans = KMeans(n_clusters=2, random_state=0).fit(data) 
print(kmeans.labels_)

3. Linux Command for Network Security Monitoring


<h1>Monitor network traffic for anomalies</h1>

sudo tcpdump -i eth0 -w capture.pcap

<h1>Analyze captured packets using Wireshark</h1>

wireshark capture.pcap
