AI Agent Glossary

# Glossary of Key AI and Agent Terms ## Essential Vocabulary for Understanding AI Agents This glossary provides clear definitions of core concepts used throughout the Agent Town Square Learning Hub. --- ## Foundational AI Concepts **Artificial Intelligence (AI)** Computer systems designed to perform tasks requiring human intelligence. **Machine Learning (ML)** Systems that learn patterns from data rather than following explicit rules. **Deep Learning** Machine learning using multi-layer neural networks. **Neural Network** Interconnected computational nodes that transform data through layered processing. **Large Language Model (LLM)** A neural network trained on massive text datasets to generate and understand language. **Training** Adjusting model parameters using data to improve performance. **Inference** Using a trained model to generate outputs or predictions. **Parameters** Internal values that determine model behavior. **Fine-tuning** Specializing a pre-trained model using additional data. **Context Window** The maximum amount of information a model can process at once. **Tokens** Units of text processed by models. **Hallucination** When a model generates plausible but incorrect information. --- ## Agent-Specific Terms **AI Agent** An AI system that perceives, decides, and acts to achieve goals. **Agent Loop** The cycle of perceive → plan → act → observe → repeat. **Tool** External capability an agent can invoke. **Function Calling** Structured mechanism for tool invocation. **Memory** Persistent or contextual information storage for agents. **Retrieval-Augmented Generation (RAG)** Combining retrieval with generation to extend knowledge. **Embeddings** Numerical representations of semantic meaning. **Multi-Agent System** Multiple agents collaborating on a shared objective. **Orchestration** Coordinating agents and workflows. --- ## Infrastructure Terms **API** Interface for software communication. **SDK** Development toolkit for building applications. **Edge Computing** Local processing near data sources. **Latency** Time delay between request and response. **Throughput** Requests handled over time. --- ## Security Terms **Authentication** Verifying identity. **Authorization** Defining permitted actions. **Encryption** Protecting data confidentiality. **Guardrails** Constraints limiting agent behavior. **Prompt Injection** Manipulating agent behavior via malicious input. --- This glossary will continue expanding as the agent ecosystem evolves.
