• Statistical Methods: To find/have the patterns and trends.
• Data Visualization: Graphically representing information to represent concepts effectively

The core applications of data science:

• Analytics and decision making in business.
• Predictive modeling and forecasting
• Segmentation and personalisation of consumers.
• Detection of fraud and risk management.

What is Artificial Intelligence (AI)?

Artificial Intelligence (AI) is the field of creating machines that can perform tasks that typically require human intelligence. It involves:

Machine Learning: Training algorithms to learn from data and make predictions.

Deep Learning: Using neural networks to model complex patterns.

Natural Language Processing (NLP): Enabling machines to understand and generate human language.

Computer Vision: Allowing machines to interpret and analyze visual data.

Key Applications of AI

• Autonomous vehicles and robotics.
• Virtual assistants and chatbots.
• Image and speech recognition.
• Game playing and strategic planning.
