What is Artificial Intelligence?

10 min

# Introduction to AI

Artificial Intelligence (AI) refers to computer systems designed to perform tasks that typically require human intelligence. These tasks include:

**Learning**: Improving performance from experience - **Reasoning**: Drawing conclusions from information - **Problem-solving**: Finding solutions to complex issues - **Perception**: Understanding data from various sources

Key Concepts
Machine Learning A subset of AI where systems learn from data without being explicitly programmed.
Deep Learning Neural networks with multiple layers that can identify patterns in unstructured data.
Natural Language Processing Teaching computers to understand and generate human language.
Real-World Applications

1. **Healthcare**: Diagnostic imaging and drug discovery 2. **Finance**: Fraud detection and risk assessment 3. **Transportation**: Autonomous vehicles and route optimization 4. **Entertainment**: Recommendation systems and content creation

Code Example

# Simple AI Example: Rule-based Decision Making

def classify_email(email):
    """Basic email classification system"""
    if 'urgent' in email.lower():
        return 'urgent'
    elif 'report' in email.lower():
        return 'work'
    else:
        return 'general'

# Using the classifier
result = classify_email("URGENT: Project deadline changed")
print(result)  # Output: urgent
