### The Hierarchy of Modern AI
* **Artificial Intelligence (AI):** The overarching field of building computing systems capable of performing tasks normally requiring human intelligence.
* **Machine Learning (ML):** A mathematical subset where models learn representations from training data instead of being explicitly programmed with rule trees.
* **Deep Learning (DL):** A sub-field using multi-layer artificial neural networks inspired by biological neuroscience.
