5. Key Technologies Used
• Machine Learning (ML) and Artificial Intelligence (AI): ML and AI algorithms
are at the core of the system, enabling the automated detection of patterns and
anomalies in transaction data.
• Data Preprocessing: Techniques such as data cleaning, feature scaling, and
feature engineering are essential for preparing the data for modeling.
• Ensemble Learning: Ensemble methods like Random Forests and Gradient
Boosting are used to combine the predictive power of multiple models, enhancing
accuracy.
• Real-time Monitoring: Technologies for real-time data processing and monitoring
enable the system to swiftly identify and respond to potentially fraudulent
transactions.
• Big Data Processing: For handling large volumes of transaction data,
technologies like Hadoop and Spark may be employed to perform data analytics
efficiently.

6. Computer Vision and Machine Learning
• Computer Vision is not typically the primary technology used in Credit
Card Fraud Detection systems. Instead, these systems primarily rely on
transaction data and behavioral patterns. Machine Learning (ML) is the
cornerstone of Credit Card Fraud Detection, and it plays a crucial role in
several aspects of the system.
• One of the primary applications of ML in this context is anomaly
detection. ML models are trained on historical transaction data, learning
to recognize patterns associated with legitimate transactions.
• Ensemble learning techniques, like Random Forests or Gradient
Boosting, are commonly used to combine the predictive power of
multiple ML models.

or app notifications to cardholders for
immediate action.
• Automated Calls: Initiate automated phone
calls to alert cardholders.
• Alert Financial Institutions: Notify the card
issuer with transaction details for action.
• Geolocation Alerts: Alert for transactions
from unusual locations.

8. Programming Languages
Python: For
machine
learning and
data analysis.
SQL: For
database
management
and data
preprocessing
.
MATLAB: For
research and
prototyping.
R: For
