Blog: A Simple, yet Technical Glossary of Terminology in AI


Demystifying Machine Learning | Glossary

Simple glossary of terms, abbreviations, and concepts related to the field and sub-fields of artificial intelligence. Based on technical definitions by pioneers and leaders in AI.

Relevant fields: [ AI ] [ machine learning ] [ deep learning] [ data science ] [ computer vision ] [ NLP ] [ human AI interaction ] [ robotics ]

Below please find a searchable glossary of terms that are relevant to the scientific field and sub-fields of artificial intelligence — on ongoing growth.

This glossary is by no means complete, if a term it’s missing, please let me know in the comments and I’ll add its definition to this growing glossary. Also, if you have feedback regarding a definition of any of the term(s), please let me know as well.


Glossary of Terms | Sorted (A-Z)

Agent: A bot used in AI related tasks.

Algorithm: Process that follows a set of rules, a problem solver — especially used by computers.

AlphaGo: Computer program that plays the board game Go. Recognized as the first computer Go program to beat a professional human Go player [5].

Artificial Intelligence (AI): Science and engineering of making computers behave in ways that, until recently, we thought required human intelligence [1].

Autonomous: Device or tool capable of operating without direct human control.

Backpropagation: A way in which neural networks train, during training they find input and provide an output, then adjust the

Black box: Complex neural network in which algorithms, contents and decision-making processes are unknown to the end-user.

Bot: An autonomous program that can interact with computer systems, programs or users. Mostly, directly or indirectly supervised by a human.

Clustering: Unsupervised machine learning.

Computational learning theory: Sub-field of AI devoted to studying the design and analysis of machine learning algorithms [4].

Computer program: Collection of instructions that perform specific tasks when launched by a computer.

Computer science: Scientific study of the principles and use of computers.

Computer vision: Interdisciplinary scientific sub-field of AI and CS that aims at giving computers a visual understanding of its input.

Convolutional neural network (CNN): Class of deep neural network used on image recognition, processing, and analysis — specifically designed to process pixel data.

Data: Digital collection of information.

Data mining: Process of examination and discovery of patterns in data to generate new information.

Datasets: A collection of related sets of data that is composed of separate elements but can be manipulated as a unit by a computer.

Data science: Interdisciplinary scientific field on processes and systems to extract knowledge or insights from data in its various forms.

Deep learning: Subset of machine learning in which layered neural networks, combined with high computing power and large datasets can create powerful machine learning models.

Deep neural network (DNN): Large computer system modeled after the human brain.

Dimensional reduction: Process of reducing the number of random variables by obtaining a set of principal variables via feature selection and/or feature extraction.

Explainable AI: AI capable to explain its decision making process.

Generative adversarial networks (GANs): Two neural networks contesting with each other in a zero-sum game framework.

Heuristics: Rules drawn from experience used to solve a problem faster than other traditional problem-solving methods in AI. While faster, a heuristic approach typically is less optimal than the classic methods it replaces.

Input: What is put in, taken in, or operated on a process or system.

Intelligence: Computational part of the ability to achieve goals in the world. Varying kinds and degrees of intelligence occur in people, many animals, and some machines.

Linear Algebra: Branch of mathematics concerning vector spaces and linear mappings between such spaces. It includes the study of lines, planes, and sub-spaces, yet is also concerned with properties common to all vector spaces.

Long short-term memory networks (LSTMs): Special kind of recurrent neural networks capable of learning long-term dependencies [2].

Machine learning (ML): Scientific branch of AI, which focuses on the study of computer algorithms that allow computer programs to automatically improve through experience [3].

Machine learning model/system: Question/answering system that takes care of processing machine learning related tasks.

Machine perception: Capability for a computer system to interpret data in a manner similar to the way humans use their senses to interact and relate to the world around them.

Natural Language Processing (NLP): Scientific branch of AI, which focuses in helping computers understand, interpret and manipulate human language.

Neural network: Computer system modeled after the human brain.

Recurrent neural network (RNN): Powerful and robust type of neural networks, capable of complex cycles in internal memory.

Turing test: Test that only passes if a human being is unable to distinguish a machine from a human.
