What does the RLHF course cover?

The course covers human preference data, supervised fine-tuning, reward modelling, pairwise ranking, policy optimization, PPO, direct preference optimization, model evaluation, red teaming, reward hacking, bias, and responsible generative AI alignment.

Who should take this Reinforcement Learning from Human Feedback course?

The course is suitable for machine learning students, AI engineers, data scientists, generative AI developers, reinforcement learning researchers, natural language processing professionals, doctoral scholars, academicians, model-evaluation teams, and responsible AI professionals.

What is Reinforcement Learning from Human Feedback?

Reinforcement Learning from Human Feedback is a model-alignment approach that uses human preferences to train a reward signal and optimize an AI system toward responses that people judge as more helpful, accurate, relevant, or safe.

What type of human preference data is used in RLHF?

RLHF commonly uses demonstrations, response rankings, pairwise comparisons, quality scores, safety labels, correction feedback, and preference annotations collected from trained evaluators or representative users.

What is a reward model in RLHF?

A reward model is trained to predict which model output a human evaluator would prefer. Its score is then used as a learning signal during policy optimization.

How is PPO used in RLHF?

Proximal Policy Optimization updates the language-model policy using reward-model scores while constraining large changes from the reference model to support more stable training.

What is Direct Preference Optimization?

Direct Preference Optimization trains a model directly from preferred and rejected response pairs without requiring a separately deployed reward model and reinforcement learning loop.

What is the difference between supervised fine-tuning and RLHF?

Supervised fine-tuning trains a model to imitate selected example responses, while RLHF uses comparative preference feedback and optimization methods to improve behaviour beyond direct imitation.

What are the main risks and limitations of RLHF?

Important limitations include biased or inconsistent feedback, reward-model errors, reward hacking, over-optimization, reduced response diversity, high annotation costs, evaluator disagreement, and incomplete representation of user values.

How are RLHF-aligned models evaluated?

Evaluation may include human preference tests, benchmark comparisons, safety assessments, adversarial testing, factuality checks, bias analysis, helpfulness ratings, refusal-quality reviews, and monitoring after deployment.

What skills can learners gain from this course?

Learners can develop skills in preference-data preparation, supervised fine-tuning, reward-model training, policy optimization, PPO and DPO workflows, model evaluation, red teaming, failure analysis, and responsible generative AI alignment.
