Algorithm: A set of computational rules to be followed to solve a mathematical problem. More recently, the term has been adopted to refer to a process to be followed, often by a computer. NIST Glossary of AI Terms, March 2023

Artificial intelligence: A broad term used to describe an engineered system where machines learn from experience, adjusting to new inputs, and potentially performing tasks previously done by humans. More specifically, it is a field of computer science dedicated to simulating intelligent behavior in computers. It may include automated decision-making. International Association of Privacy Professionals, Glossary, March 2024).  This definition provides a high-level summary of AI definitions found in NIST's The Language of Trustworthy AI: An In-Depth Glossary of Terms (March 22, 2023).

AI prompt: An instruction or command given to an artificial intelligence tool to carry out a task or function. NIST Glossary of AI Terms, March 2023

Confidential information: All information about the organization, its operations, clients or employees that is subject to reasonable efforts by the organization to maintain its confidentiality and that is not typically disclosed by custom or law to people who are not affiliated with the organization but does not qualify as a trade secret. NIST Glossary of AI Terms, March 2023

Generative AI: A kind of artificial intelligence capable of generating new content such as code, images, music, text (e.g., ChatGPT), simulations, 3D objects, videos, etc. It is considered an important part of AI research and development, as it has the potential to revolutionize many industries, including entertainment, art and design. NIST Glossary of AI Terms, March 2023

Hallucination: Generated content that is nonsensical or unfaithful to the provided source content. NIST Glossary of AI Terms, March 2023

Machine learning: The study or the application of computer algorithms that improve automatically through experience. Machine-learning algorithms build a model based on training data in order to perform a specific task, like aiding in prediction or decision-making processes, without necessarily being explicitly programmed to do so. NIST Glossary of AI Terms, March 2023

Personally identifiable information (PII): Information that can be used to distinguish or trace an individual’s identity—such as name, Social Security number, biometric data records – either alone or when combined with other personal or identifying information that is linked or linkable to a specific individual (e.g., date and place of birth, mother’s maiden name, etc.). NIST Glossary of AI Terms, March 2023

Trustworthy AI: Characteristics of trustworthy AI systems include valid and reliable, safe, secure and resilient, accountable and transparent, explainable and interpretable, privacy-enhanced, and fair with harmful bias managed. NIST Glossary of AI Terms, March 2023
