Study Notes
SageMaker Clarify
- Evaluates foundation models to compare performance (e.g., model A vs. model B).
- Provides insights into model performance on specific tasks, like brand voice (25% for model A vs. 75% for model B) and relevance (64% for model A vs. 93% for model B).
- Uses tasks and evaluates models on human factors (friendliness, humor).
- Leverages AWS-managed teams or user-provided employees for human evaluation.
- Allows use of built-in datasets or user-provided datasets and questions.
- Offers built-in metrics and algorithms.
- Part of SageMaker Studio.
Model Explainability
- Explains how models make predictions.
- Aids in understanding model behavior before deployment.
- Useful for debugging incorrect predictions after deployment.
- Enhances trust and understanding of models.
- Example: Explaining why a loan applicant was rejected (e.g., based on maturity month, loan amount).
Bias Detection
- Identifies human biases in datasets and models.
- Measures bias using statistical metrics.
- Automatically detects bias in specified input features.
- Example: Detects class imbalance (one group significantly outnumbers another) or imbalances in data distribution.
SageMaker Ground Truth
- Based on Reinforcement Learning from Human Feedback (RLHF).
- Used for model review, customization, and evaluation.
- Aligns models with human preferences.
- Involves human feedback in the reward function for reinforcement learning, enabling model creation and evaluation from a human perspective.
- Enhances models by incorporating human preferences (e.g., business-oriented).
- Example: Providing human labeling (dog, ship, cat) for data annotation.
SageMaker Ground Truth Plus
- A feature within SageMaker Ground Truth.
