AI Glossary (Updated for 2023)
Artificial Intelligence (AI): The ability of a machine to simulate human intelligence and perform tasks like reasoning, learning, planning and problem-solving. The broader goal of AI research is to create intelligent machines capable of complex thought and action on par with humans.
Machine Learning: A subset of AI focused on building algorithms that can learn and improve from experience without being explicitly programmed. Machine learning algorithms use training data to make predictions or decisions without relying on rule-based programming.
Deep Learning: A machine learning technique that trains artificial neural networks on large sets of data, with each layer learning increasingly higher level features. Deep learning algorithms perform well at tasks like image recognition, natural language processing, and prediction.
Neural Networks: Computing systems modeled on the biological neural networks of animal brains. Neural networks consist of layers of simple processing nodes that operate as interconnected networks. Data is processed through the network and weighted connections are adjusted based on results.
Computer Vision: The field of AI focused on enabling machines to identify, process and analyze visual data such as digital images and videos. Computer vision powers applications like image recognition, video surveillance and self-driving cars.
Natural Language Processing (NLP): The branch of AI dealing with the ability of computers to understand, interpret and manipulate human language. NLP powers voice assistants, language translation, sentiment analysis, text generation and summarization.
Reinforcement Learning: A machine learning technique in which software agents learn by interacting with an environment and receiving positive or negative feedback rewards for their actions. The agent seeks to maximize cumulative reward through trial and error.
Robotics: The field of technology focused on designing and building robots or autonomous machines able to perform tasks and assist humans. AI advances like computer vision and deep learning have enabled major improvements in robotic capabilities.
Expert System: A type of AI system that uses a knowledge base of human expertise to provide advice or make decisions in specific domains like medicine, engineering, etc. Expert systems mimic the decision making of human specialists.
Supervised Learning: A machine learning approach in which algorithms are trained on labeled datasets containing correct example inputs and outputs. The system learns by comparing its predictions to the known “ground truth” in training data.
Unsupervised Learning: Machine learning models that are provided unlabeled data and left to find patterns and relationships on their own without human guidance. Clustering and dimension reduction are common unsupervised learning tasks.:
Automated Reasoning: The field of AI focused on designing systems that can reason, draw conclusions, and solve logical problems automatically. Methods include mathematical logic, knowledge representation, and formal reasoning.
Knowledge Representation: Techniques for encoding human knowledge in a form that can be understood and processed by AI systems. Common approaches include rules, logic, ontologies, semantic networks, and concept maps.
Robot Learning: Methods that enable robots to learn from experience and environmental interaction, rather than relying solely on predefined programming. Approaches include reinforcement learning, neural networks, imitation learning, and developmental robotics.
Affective Computing: The study and development of systems that can recognize, interpret, simulate, and process human affects like emotions. This enables more natural emotional intelligence for human-AI interaction.
Computer Audition: The field dealing with how computers can recognize, understand, and synthesize various auditory signals and sound stimuli. Includes speech recognition, sound event detection, auditory scene analysis, and speech synthesis.
Automated Planning: AI methods focused on creating and executing plans or action sequences to achieve prescribed goals. Planning enables intelligent agents to reason about complex objectives in domains like navigation, manufacturing, logistics, etc.
Multi-Agent Systems: Systems composed of multiple interacting intelligent agents coordinating behaviors to solve problems. Agents may compete, cooperate, or use negotiation tactics. Common in fields like robotics, economics, transportation.
Explainable AI (XAI): Systems and methods that enable AI and machine learning models to explain their purpose, reasoning, and decisions to humans in a transparent, interpretable manner. Improves transparency.
Transfer Learning: AI techniques focused on transferring learned patterns in one domain or task to accelerate learning and improve performance in a related domain or new task. Enables reuse of previous model training.
Sentiment Analysis: The use of NLP and machine learning to systematically identify, extract, and study affective states and subjective information in written and spoken language. Used to determine sentiment, opinions, emotions towards certain topics.
Predictive Analytics: The use of data and AI modeling techniques like machine learning to make predictions about future events and outcomes. Common in fields like sales forecasting, investment predictions, and risk assessment.
Speech Synthesis: The artificial production of human speech, enabled by AI fields like NLP and computer audition. Also referred to as text-to-speech (TTS) synthesis. Used to create voice assistants and reading systems for the visually impaired.
Artificial Creativity: Development of AI systems that can mimic, enhance, or replace human creativity and creative expression in domains like art, music, literature, design, humor, and storytelling.
