Core AI Concepts
Types of AI
- Artificial Intelligence (AI): Machines that mimic human cognitive functions
- Machine Learning (ML): Systems that learn from data without explicit programming
- Deep Learning: ML using neural networks with many layers
- Generative AI: AI that creates new content (text, images, code)
Machine Learning Types
- Supervised Learning: Learn from labeled data (classification, regression)
- Unsupervised Learning: Find patterns in unlabeled data (clustering)
- Reinforcement Learning: Learn through trial and error with rewards
Common ML Tasks
- Classification: Predict categories (spam/not spam, cat/dog)
- Regression: Predict numeric values (price, temperature)
- Clustering: Group similar items (customer segments)
- Anomaly Detection: Find unusual patterns (fraud detection)
Responsible AI Principles
Microsoft's six principles for responsible AI:
- Fairness: AI systems should treat all people fairly
- Reliability & Safety: AI systems should perform reliably and safely
- Privacy & Security: AI systems should be secure and respect privacy
- Inclusiveness: AI systems should empower everyone
- Transparency: AI systems should be understandable
- Accountability: People should be accountable for AI systems
Exam Tip: Responsible AI is heavily tested. Know all six principles and be able to identify which principle applies to given scenarios.
