Section 1: Core AI Fundamentals
AI Ethics / Responsible AI - Responsible AI refers to the principles and practices that ensure AI systems are used safely, fairly and transparently, minimizing bias and unintended harm.
Algorithm - An algorithm is a defined set of rules or instructions that a computer follows to solve a problem or complete a task. Algorithms underpin all AI systems, determining how data is processed and how decisions are made.
Artificial Intelligence (AI) - Artificial intelligence refers to computer systems designed to perform tasks that traditionally require human intelligence. These tasks include understanding language, recognizing patterns, making decisions and adapting based on new information. In hospitality, AI is used across marketing, operations, guest services and revenue management.
Context Window - The context window refers to the amount of text or information an AI system can consider at one time when generating a response.
Data Privacy (AI Context) - Data privacy in AI refers to how personal and operational data is collected, stored and used responsibly within AI systems.
Deep Learning - Deep learning is a more advanced type of machine learning that uses layered neural networks to process large and complex datasets. It is particularly effective for tasks involving language, images and behavioral patterns. Examples can be tools that analyze guest photos, voice requests or complex booking patterns.
Embeddings - Embeddings are mathematical representations of words, phrases or concepts that allow AI systems to understand meaning and relationships between ideas rather than relying on exact keyword matches. For example, they enable AI models to recognize that “pet-friendly” and “we welcome dogs” mean the same thing in an online listing.
Fine-Tuning - Fine-tuning is the process of taking an already trained model and refining it using specialized data to improve performance for a specific use case. For hospitality operations, this is where a general AI model adapts and can speak in the brand’s voice or know specific property details.
Guardrails - Guardrails are rules, constraints or controls built into AI systems to ensure outputs remain accurate, safe and appropriate. For hospitality organizations, these are rules that stop chatbots from promising discounts or policies that are not authorized.
Hallucination - A hallucination occurs when an AI system generates information that appears accurate but is incorrect or fabricated.
Hallucination Mitigation - Hallucination mitigation refers to methods used to reduce the risk of incorrect AI outputs, often through improved data sources, system design or validation processes.
Large Language Model (LLM) - A large language model is an AI system trained using vast amounts of text data to understand, interpret and generate human language. These models power tools such as chatbots, virtual assistants and AI search platforms. For hotel applications, it can be the technology behind a chatbot, answering guest questions in natural, human-like language.
Latency - Latency is the time delay between a request to an AI system and the system providing a response.
Machine Learning (ML) - Machine learning is a branch of AI that enables systems to learn from data rather than relying solely on fixed rules. Over time, these systems improve their performance by identifying patterns and adjusting their outputs based on new inputs. For example, a system might become better at predicting cancellations or no-shows as it processes more booking history.
Model Training - Model training is the process of teaching an AI system by exposing it to large datasets so it can learn patterns and relationships.
Natural Language Processing (NLP) - Natural language processing is the field of AI that focuses on enabling machines to read, interpret and generate human language in a meaningful way. For example, being able to have a system read and route guest emails or messages by topic.
Natural Language Understanding (NLU) - Natural language understanding is a subset of NLP that focuses specifically on interpreting meaning and intent behind language, rather than simply processing words.
Token - A token is a unit of text processed by AI systems. It can be a full word, part of a word or even a character. Tokens determine how AI systems read and generate language.
Transformer - A transformer is a type of AI model architecture that allows systems to understand relationships between words and concepts across entire sentences or conversations. It is the foundational technology behind modern language-based AI systems.
