Artificial Intelligence AI Ethics and Bias 3

Question 1

What is 'hallucination' in large language models?

Accepted Answer

Generating confident but factually incorrect or fabricated information

Answer

LLM hallucination occurs when the model produces plausible-sounding but false or invented information with unwarranted confidence.

Question 2

What is a 'model card' in responsible AI?

Accepted Answer

A document disclosing a model's intended uses, limitations, performance, and ethical considerations

Answer

Model cards, proposed by Google, are documentation accompanying AI models to communicate their capabilities, limitations, and ethical considerations.

Question 3

What is RLHF (Reinforcement Learning from Human Feedback) used for?

Accepted Answer

Aligning LLM outputs with human preferences using reward signals from human raters

Answer

RLHF trains a reward model from human preference comparisons, then uses RL to fine-tune the LLM to produce higher-rated outputs.

Question 4

What is 'consent' in AI data collection?

Accepted Answer

Individuals knowingly and voluntarily agreeing to have their data collected and used

Answer

Consent requires that people are informed about data collection and freely agree to it before their data is used to train AI models.

Question 5

What is 'AI safety' research broadly focused on?

Accepted Answer

Preventing AI systems from causing unintended or catastrophic harm

Answer

AI safety research works to ensure that AI systems behave reliably, predictably, and without causing unintended harm as they become more capable.
