AI in Industry: Real-world Applications

Duration: 5 min

This module delves into the practical applications of AI and machine learning within various industries. Understanding these applications is crucial for leveraging AI to solve real-world problems, optimize processes, and drive innovation.

Predictive Maintenance in Manufacturing

Predictive maintenance uses AI algorithms to predict equipment failures before they occur. By analyzing sensor data, machine learning models can identify patterns that indicate potential failures, allowing for timely maintenance and reducing downtime.

import pandas as pd
from sklearn.model_selection import train_test_split
from sklearn.ensemble import RandomForestClassifier
from sklearn.metrics import accuracy_score

# Load dataset
data = pd.read_csv('machine_data.csv')

# Features and target
X = data.drop('failure', axis=1)
y = data['failure']

# Split data
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2, random_state=42)

# Train model
model = RandomForestClassifier()
model.fit(X_train, y_train)

# Predict
y_pred = model.predict(X_test)

# Evaluate
accuracy = accuracy_score(y_test, y_pred)
print(f'Accuracy: {accuracy:.2f}')

Try it in Google Colab:

Accuracy: 0.85

Customer Segmentation in Retail

Customer segmentation involves dividing a customer base into groups of individuals that share similar characteristics. Machine learning algorithms can analyze purchasing behavior, demographics, and other data to create these segments, enabling targeted marketing and personalized services.

import pandas as pd
from sklearn.cluster import KMeans
import matplotlib.pyplot as plt

# Load dataset
data = pd.read_csv('customer_data.csv')

# Features
X = data[['age', 'annual_income','spending_score']]

# Apply KMeans
kmeans = KMeans(n_clusters=3, random_state=42)
kmeans.fit(X)

# Add cluster labels
data['cluster'] = kmeans.labels_

# Plot
plt.scatter(data['annual_income'], data['spending_score'], c=data['cluster'], cmap='viridis')
plt.scatter(kmeans.cluster_centers_[:, 1], kmeans.cluster_centers_[:, 2], s=300, c='red')
plt.xlabel('Annual Income')
plt.ylabel('Spending Score')
plt.title('Customer Segments')
plt.show()

💡 Tip: When applying KMeans for customer segmentation, experiment with different values of 'n_clusters' to find the optimal number of segments.
