Welcome to AI & ML Fundamentals! This course will introduce you to the fascinating world of Artificial Intelligence and Machine Learning. Whether you're completely new to AI or looking to solidify your understanding, this course will provide you with a strong foundation.

What is Artificial Intelligence?

Artificial Intelligence (AI) is the simulation of human intelligence processes by machines, especially computer systems. These processes include learning, reasoning, problem-solving, perception, and language understanding. AI enables machines to perform tasks that typically require human intelligence.

Types of AI

• Narrow AI (Weak AI) - AI systems designed for specific tasks like voice assistants, recommendation systems, or image recognition. This is the AI we use today.
• General AI (Strong AI) - Hypothetical AI with human-like intelligence that can understand, learn, and apply knowledge across various domains.
• Super AI - Theoretical AI that surpasses human intelligence in all aspects.

Key Concepts in AI

• Machine Learning - Subset of AI where systems learn from data without being explicitly programmed
• Deep Learning - Advanced ML using neural networks with multiple layers
• Natural Language Processing - Enabling machines to understand and generate human language
• Computer Vision - Teaching machines to interpret and understand visual information
• Reinforcement Learning - Learning through trial and error with rewards and penalties

Applied example: evaluate before serving

Suppose a classifier predicts whether a support ticket needs escalation. Split data before fitting preprocessing. Keep tickets from the same conversation together, and reserve later tickets to check performance on future traffic.

Illustrative test: of 100 tickets that need escalation, the model finds 80 and misses 20. Recall is 80%. If it raises 100 alerts, precision is also 80%. These invented counts demonstrate the calculation; they are not a production target. Review error costs and slices before choosing a threshold.

Read scikit-learn’s guidance on data leakage, then connect serving to observability and SLOs.
