1.1.2. The AI Hierarchy: AI → ML → Deep Learning → Transformers

AI concepts nest inside each other like Russian dolls. Understanding this hierarchy prevents confusion when the exam uses these terms.

The following diagram illustrates how these concepts relate:

The following table clarifies each level of the hierarchy:

LevelDefinitionKey Characteristic
Artificial IntelligenceAny system that mimics human intelligenceBroadest category—includes rule-based systems
Machine LearningAI that learns patterns from dataImproves with more data, no explicit programming
Deep LearningML using neural networks with many layersHandles complex patterns in images, text, audio
TransformersDeep learning architecture using attentionPowers modern language models (GPT, BERT)
