Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and expressions
related to conformity assessment, as well as information about ISO's adherence to the World Trade
Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www.iso.org/iso/foreword.html.
Amendment 1 to ISO/IEC 22989:2022 was prepared by Joint Technical Committee ISO/IEC/JTC1, Information
technology, Subcommittee SC 42, Artificial intelligence.

Page 24, Clause 5.11
Add new sub clause 5.11.10 and 5.11.11:
5.11.10  Self-supervised machine learning
Self-supervised machine learning is an approach for training on unlabelled data using algorithms that
normally belong to supervised machine learning. This is achieved by using implicit labels, such as the
input itself, part of the input, or any other label that can be easily generated from the raw data. Refer to
ISO/IEC 23053 for further information on self-supervised machine learning.
5.11.11  Retrieval-augmented generation (RAG)
RAG is a technique that is used to augment an LLM with new or domain specific data without the need to
fine tune or retrain the model (see 5.24). In RAG a data source with relevant text is used to populate the
context window of the LLM in addition to the system prompt and user prompt, if any. The data source can
be one or more specific files or a database that is queried based on the input. In the case of the database the
input is converted to a set of keywords or phrases or a vector query depending on the underlying database
technology. This conversion can be accomplished by NLP techniques like keyword search or an embedding
generated by an LLM. RAG helps to mitigate hallucinations of the AI systems.

samples that are representative of the dataset, and one or more discriminators, which try to distinguish
generated samples from real ones. Refer to ISO/IEC 23053 for further information on GANs.
