Core Content:

AI Hierarchy: AI encompasses all technologies enabling machines to mimic human intelligence. Machine Learning (ML) is a subset where machines learn from data without explicit programming. Deep Learning (DL) uses neural networks with multiple layers. Generative AI, within DL, creates new content (text, images, audio, video).

7 AI Workloads and Azure Services:

Workload	Azure Service	Key Purpose
Content Moderation	Azure AI Content Safety Studio	Detect/filter harmful content in text and images
Personalization	Azure AI Personalizer	Reinforcement learning for real-time decisions
Computer Vision	Azure AI Vision	Analyze images/videos: OCR, object detection, face recognition
NLP	Azure AI Language	NER, PII detection, sentiment analysis, summarization, CLU

Core Content:

ML Workflow: (1) Train — feed labeled/unlabeled data to learn patterns; (2) Apply Algorithm — find best-fit model (linear regression, logistic regression, K-means, etc.); (3) Inferencing — use trained model to predict on new data.

Types of ML:

• Supervised Learning — uses labeled data (regression, classification). Example: predicting house prices
• Unsupervised Learning — no labels, finds patterns (clustering). Example: customer segmentation with K-means
• Reinforcement Learning — learns by trial-and-error with rewards. Example: Azure AI Personalizer

Regression: Predicts continuous numerical values. Key metrics:

• MAE (Mean Absolute Error) — average of absolute differences
• MSE (Mean Squared Error) — average of squared differences (penalizes larger errors)
• RMSE (Root MSE) — MSE in original units
• R² (Coefficient of Determination) — proportion of variance explained (0-1, higher = better)

Classification: Assigns data to predefined categories.

• Binary: two classes (e.g., spam/not-spam). Uses logistic regression. Metrics: Accuracy, Precision, Recall, F1 Score, AUC
• Multiclass: multiple classes. One-vs-Rest (OVR) approach builds separate binary classifiers per class

Clustering: Groups similar data without labels. K-means is the most common algorithm.

Deep Learning: Uses neural networks with multiple layers. Enables breakthroughs in image recognition, speech, and NLP.

Closer to 1 = better fit.

[TF-1] Inferencing is the step where the trained model generates predictions on new data. Answer: True | After training and validation, inferencing applies the model to new, unseen data to produce predictions.

[TF-2] In K-means clustering, you need labeled data to train the model. Answer: False | K-means is unsupervised — it groups data based on similarities without requiring any labels.
