Domain 1: Fundamentals of AI and ML
1.1 Explain basic AI concepts and terminologies
- AI is the broad field of building systems that perform tasks requiring human-like intelligence, such as understanding text, recognizing images, reasoning, planning, and making predictions.
- Machine learning is a subset of AI where systems learn patterns from data instead of being explicitly programmed for every rule.
- Deep learning uses neural networks with many layers. It is commonly used for image recognition, speech recognition, language models, and large-scale pattern recognition.
- Generative AI creates new content such as text, images, audio, video, code, and summaries. Foundation models and large language models are common examples.
- Agentic AI uses models plus tools, memory, and workflows to take steps toward a goal. Agents can call APIs, retrieve data, and coordinate tasks.
- Inferencing means using a trained model to produce predictions or outputs. Batch inferencing works on many records later, real-time inferencing responds immediately, asynchronous inferencing handles longer jobs, and serverless inferencing scales without fixed servers.
- Data types include structured tables, semi-structured JSON/logs, unstructured text/images/audio, time-series data, labeled training data, and unlabeled data.
1.2 Identify practical use cases for AI
- Regression predicts continuous numeric values, such as sales amount or delivery time.
- Classification predicts categories, such as fraud/not fraud or high/medium/low risk.
- Clustering groups similar items without predefined labels, such as customer segmentation.
- Computer vision identifies objects, detects defects, extracts text from images, and supports safety monitoring.
- NLP handles text tasks such as sentiment analysis, classification, entity extraction, summarization, and translation.
- Speech services convert speech to text, text to speech, or support conversational voice interfaces.
- Traditional ML is often better when the output must be explainable, highly structured, cheaper to run, or built around tabular prediction. Foundation models are better for flexible language, summarization, generation, reasoning, and multi-modal tasks.
1.3 Describe the AI/ML development lifecycle
- A common lifecycle is business problem definition, data collection, data preparation, model selection, training or customization, evaluation, deployment, monitoring, feedback, and retraining.
- MLOps focuses on repeatable experiments, versioning, automated deployment, monitoring, governance, and reducing technical debt.
- Key ML metrics include accuracy, precision, recall, F1 score, false positives, false negatives, latency, and cost per prediction.
- Business metrics include ROI, user satisfaction, development cost, adoption, task completion rate, conversion rate, and customer feedback.
- AWS services in this area include Amazon SageMaker AI for ML development, Amazon Bedrock for foundation model applications, Amazon Q for AI assistance, Amazon Transcribe, Translate, Comprehend, Lex, Polly, and Rekognition for managed AI capabilities.
- Know the difference between AI, ML, deep learning, GenAI, and agentic AI.
- Choose regression for numeric prediction, classification for category prediction, and clustering for grouping without labels.
- The exam is foundational. Expect service matching and concept selection, not coding or math-heavy modeling.
