How it works — components
Language understanding
CLU / LUIS intents and entities map free text to structured actions — the theory is to separate "what the user wants" (intent) from "the values" (entities) so downstream code stays deterministic.
Document intelligence
Form Recognizer / OCR turns unstructured PDFs and images into key-value pairs and tables using layout models trained on spatial features, not just characters.
Vision & speech
Pretrained Computer Vision and Speech-to-Text services expose embeddings/transcripts via REST; the lab covers when to use prebuilt models vs. custom training.
Responsible AI
Content safety, confidence thresholds, and human-in-the-loop review — the exam emphasizes calibrating automation against the cost of a wrong prediction.
