Understand and apply Reinforcement Learning from Human Feedback (RLHF) in AI alignment and machine learning applications. Learn how human-in-the-loop training aligns large language models (LLMs) with human preferences and AI safety.

Key Features

Master principles of Reinforcement Learning from Human Feedback (RLHF) and AI alignment techniques
Apply RLHF to large language models (LLMs) and practical LLM fine-tuning workflows
Learn reward modeling, preference learning, and policy optimization to align AI models with human values
Purchase of the print or Kindle book includes a free PDF eBook

Book Description

Reinforcement Learning from Human Feedback (RLHF) is a powerful approach to AI alignment and human-centered machine learning. By combining reinforcement learning algorithms with human feedback signals, RLHF has become a key method for improving the safety, reliability, and alignment of large language models (LLMs).

This book begins with the foundations of reinforcement learning and policy optimization, including algorithms such as proximal policy optimization (PPO), and explains how reward models and human preference learning help fine-tune AI systems and generative AI models. You’ll gain practical insight into how RLHF pipelines optimize models to better match human preferences and real-world objectives.

You’ll also explore strategies for collecting human feedback data, training reward models, and improving LLM fine-tuning and alignment workflows. Key challenges—including bias in human feedback, scalability of RLHF training, and reward design—are addressed with practical solutions.

The final chapters examine advanced AI alignment methods, model evaluation, and AI safety considerations. By the end, you’ll have the skills to apply RLHF to large language models and generative AI systems, building AI applications aligned with human values.

What you will learn

Master the essentials of reinforcement learning for RLHF
Understand how RLHF can be applied across diverse AI problems
Build and apply reward models to guide reinforcement learning agents
Learn effective strategies for collecting human preference data
Fine-tune large language models using reward-driven optimization
Address challenges of RLHF, including bias and data costs
Explore emerging approaches in RLHF, AI evaluation, and safety

Who this book is for

This book is for AI practitioners, machine learning engineers, and researchers looking to implement Reinforcement Learning from Human Feedback (RLHF) in real-world projects. It also supports students and researchers exploring AI alignment, reinforcement learning, and large language model training in a single, structured resource. Industry leaders and decision-makers will gain insight into evaluating RLHF, AI alignment strategies, and responsible adoption of generative AI and LLM-based systems.

Diritto di recesso

Instructions for revocation

Right of withdrawal for the sale of goods

Revocation right for consumers
(A ‘consumer' is any natural person who concludes a legal transaction which, to an overwhelming extent, cannot be attributed to either his commercial or independent professional activities.)

Instructions for revocation

Revocation right
You have the right to revoke this contract within 14 days without specifying any reasons.
The revocation period is 14 days with effect from the day,

on which you or a third party nominated by you, which is not the carrier, had taken possession of the products, provided you had ordered one or more products within the scope of a standard order and this/these product/products is/are delivered uniformly;
on which you or a third party nominated by you, which is not the carrier, had taken possession of the last product, provided you had ordered several products within the scope of a standard order and these products are delivered separately;
on which you or a third party nominated by you, which is not the carrier, had taken possession of the last part delivery or the last unit, provided you had ordered a product, which is delivered in several part deliveries or units;

To exercise your right of withdrawal, you must inform us (preigu GmbH & Co. KG, Lengericher Landstr. 19, 49078 Osnabrück, Telephone number: +49 (0) 541 / 580 72 84, E-Mail address: mail@preigu.de) by means of a clear declaration (e.g. a letter sent by post, or an e-mail) of your decision to withdraw from this contract. You can use the attached model withdrawal form for this purpose, which is, however, not mandatory.

You can also exercise your right of withdrawal online by clicking on a button labelled accordingly (such as ‘Withdraw from contract' or similar) on the AbeBooks/ZVAB website. If you use this online function, you will immediately receive a confirmation of receipt on a durable medium (e.g. via email) containing information on the content of the withdrawal notice, as well as the date and time of its receipt.

In order to safeguard the revocation period, it is sufficient that you send the notification about the exercise of the revocation right before the expiry of the revocation period.

Consequences of the revocation

If you revoke this contract, we shall repay all the payments, which we received from you, including the delivery costs (with the exception of additional costs, which arise from that fact that you selected a form of delivery other than the most reasonable standard delivery offered by us), immediately and at the latest within 14 days from the day on which we received the notification about the revocation of this contract from you. We use the same means of payment, which you had originally used during the original transaction, for this repayment unless expressly agreed otherwise with you; you will not be charged any fees owing to this repayment.

We can refuse the repayment until the products are returned to us or until you have furnished evidence that you have sent the products back to us, depending on whichever is earlier.

You must return or transfer the products to us immediately and, in any case, at the latest within 14 days with effect from the day on which you inform us of the revocation of this contract. The deadline is maintained if you send the products before the expiry of the 14 day deadline.

You bear the direct costs for returning the products.

You must pay for any depreciation of the products only if this depreciation can be attributed to any handling with you that was not necessary for checking the condition, features and functionality of the products.

Criteria for exclusion or expiry

The revocation right is not available for contracts

for delivery of products, which are not prefabricated and for whose manufacturing an individual selection or stipulation by the consumer is important or which are clearly tailored to the personal requirements of the consumer;
for delivery of products, which can spoil quickly or whose use-by date would be exceeded quickly;
for delivery of alcoholic drinks, whose price was agreed at the time of concluding the contract, which however can be delivered 30 days after the conclusion of the contract at the earliest and whose current value depends on the fluctuations in the market, on which the entrepreneur has no influence;
for delivery of newspapers, periodicals or magazines with the exception of subscription contracts. The revocation right expires prematurely in case of contracts
for delivery of sealed products, which are not suitable for return for reasons of health protection or hygiene if their seal has been removed after the delivery;
for delivery of products if they have been mixed inseparably with other goods after the delivery, owing to their condition;
for delivery of sound or video recording or computer software in a sealed package if the seal has been removed after the delivery.
