AI Foundations
Explain how modern AI actually works, in plain language.
What you will learn
- What is AI5 minSoftware that learns patterns from data instead of following fixed rules.
- How machines learn7 minFitting a function to examples so it generalizes to new cases.
- Neural networks8 minLayers of simple weighted units that together approximate complex functions.
- Training vs inference6 minThe expensive one-time learning phase versus the cheap repeated answering phase.
- What is a large language model7 minA next-token predictor trained on vast text that becomes broadly capable.
- Tokens and context6 minText is chunked into tokens; the context window is how many the model can hold at once.
- Embeddings8 minTurning text into vectors whose distances capture meaning.
