1. AI vs ML vs Deep Learning
These terms are often confused but represent nested concepts with increasing specificity.
Relationship:
Artificial Intelligence (broadest)
└─ Machine Learning
└─ Deep Learning
└─ Generative AI (e.g., LLMs)2. Types of Machine Learning
3. ML Workflow on AWS
ML Workflow: 1. COLLECT DATA S3, Kinesis, DMS, Glue ETL, Data Lake 2. PREPARE DATA Glue DataBrew (clean), SageMaker Data Wrangler (transform) Label: SageMaker Ground Truth 3. BUILD MODEL SageMaker: built-in algorithms, custom code, notebooks Choose: algorithm, hyperparameters, training data 4. TRAIN MODEL SageMaker Training Jobs: managed GPU/CPU instances Distributed training for large models 5. EVALUATE MODEL Metrics: accuracy, precision, recall, F1, AUC SageMaker Model Monitor: detect drift 6. DEPLOY MODEL SageMaker Endpoints: real-time inference SageMaker Batch Transform: batch inference SageMaker Serverless Inference: pay per request 7. MONITOR SageMaker Model Monitor: data drift, model quality
4. Key ML Concepts for the Exam
Exam Tip
ML Concepts: "Learn from labeled data" = Supervised. "Find patterns in unlabeled data" = Unsupervised. "Trial-and-error with rewards" = Reinforcement. "Model too specific to training data" = Overfitting. "Model too simple" = Underfitting. "Label training data" = SageMaker Ground Truth. "Tune settings before training" = Hyperparameter tuning.
