Amazon Web Services Updated AIF-C01 Exam Questions and Answers by leonie

The regression model is a fundamental type of supervised machine learning algorithm that is specifically designed to make numeric predictions. In regression tasks, the goal is to predict a continuous numerical value based on input features. This contrasts with classification, which predicts discrete labels.

According to AWS documentation:

“Regression models are used for predicting a continuous value. Examples include predicting house prices, stock market prices, or customer credit limits.”

(Reference: AWS Machine Learning Foundations: Regression, AWS AI Practitioner Study Guide)

Option A (Diffusion) relates to generative models and is not primarily used for numeric prediction.

Option C (Transformer) is a neural network architecture, often used for sequence modeling tasks (e.g., NLP).

Option D (Multi-modal) describes a model handling multiple data types, not specifically numeric prediction.

Explainability refers to the ability of an AI system to make its decision-making process clear and understandable to humans.

A is correct:

"Explainability is crucial for human-centered AI, especially in healthcare, to ensure that doctors and patients understand the rationale behind AI-driven recommendations."

(Reference: AWS Responsible AI)

B relates to protecting data, not explanations.

C is about treating groups equally.

D is about managing data lifecycle, not providing rationales.

Comprehensive and Detailed Explanation From Exact Extract:

The best practice for mitigating bias in AI/ML models, according to AWS and responsible AI frameworks, is to ensure that the training data is representative and diverse. If a model demonstrates bias (such as favoring a particular demographic), the recommended, cost-effective approach is to collect additional data from underrepresented groups and retrain (fine-tune) the model with the improved dataset.

A. Include more diverse training data. Fine-tune the model again by using the new data:

“The most effective method to reduce model bias is to curate and include diverse, representative training data, then retrain or fine-tune the model.”

(Reference: AWS Responsible AI, SageMaker Clarify Bias Mitigation)

B (RAG) is unrelated to model fairness or bias mitigation; it’s for grounding LLMs with external knowledge.

C (AWS Trusted Advisor) is for AWS resource optimization/security—not for ML model bias detection or mitigation.

D (Pre-train a new LLM) would be extremely costly and is unnecessary; fine-tuning with better data is much more efficient.

AI governance frameworks aim to build trust and deploy human-centered AI technologies by establishing guidelines and policies for data usage, transparency, responsible AI practices, and compliance with regulations. This ensures ethical and accountable AI development and deployment.

Exact Extract from AWS AI Documents:

From the AWS Documentation on Responsible AI:

"AI governance frameworks establish trust in AI technologies by developing policies and guidelines for data management, transparency, responsible AI practices, and compliance with regulatory requirements, ensuring human-centered and ethical AI deployment."

Detailed Explanation:

Option A: Expanding initiatives across business units to create long-term business valueWhile expanding initiatives can drive value, it is not a core characteristic of AI governance frameworks focused on trust and human-centered AI.

Option B: Ensuring alignment with business standards, revenue goals, and stakeholder expectationsAlignment with business goals is important but not specific to AI governance frameworks for building trust and ethical AI deployment.

Option C: Overcoming challenges to drive business transformation and growthOvercoming challenges is a general business goal, not a defining characteristic of AI governance frameworks.

Option D: Developing policies and guidelines for data, transparency, responsible AI, and complianceThis is the correct answer. This option directly describes the core components of AI governance frameworks that ensure trust and ethical AI deployment.
