Active Server Pages
Active Server Pages, later called Classic ASP, is Microsoft's server-side scripting technology for dynamic web pages, introduced in December 1996 with Internet Information Server 3.0 and running on IIS.
Active site prediction
Active site prediction is a set of computational methods that identify the likely ligand-binding or catalytic regions of a protein from its sequence or structure.
Active Worlds
Active Worlds is a 3D online virtual world platform launched in June 1995, where users explore shared worlds as avatars, chat, and build permanent structures on virtual land.
ActiveX
ActiveX is a Microsoft framework, announced in 1996, for reusable software components built on COM that can embed in applications and web pages, now considered legacy.
Activity diagram
An activity diagram is a Unified Modeling Language (UML) behavioral diagram that models workflows and computations as a flow of actions, decisions, and parallel paths.
Activity schema
Activity Schema is an open, warehouse-native data modeling standard (spec 2.0, 2022) storing business data as one time-series activity stream table: entity, timestamp, activity, features; temporal self-joins, immutable activities, optional entity tables.
Activity Streams
Activity Streams is a data format for encoding activity and event metadata across the social web, with a JSON-based 2.0 version published as a W3C Recommendation and used by ActivityPub.
ActivityNet
ActivityNet is a large-scale video benchmark for human activity understanding introduced at CVPR 2015, with untrimmed YouTube videos and temporal annotations for classifying and localizing daily activities.
Actix Web
Actix Web is a web framework for the Rust programming language that provides an HTTP server, routing, extractors, and middleware, known for top TechEmpower benchmark performance.
Actor model
The actor model, also known as actor modeling, is a mathematical model of concurrent computation in which actors process messages one at a time without shared memory, proposed in 1973.
Actor-critic algorithm
The actor-critic algorithm is a reinforcement learning method combining a policy, the actor, with a value function, the critic, introduced by Barto, Sutton, and Anderson in 1983.
Actor-critic methods
Actor-critic methods are reinforcement learning algorithms combining an actor policy with a critic value function, introduced in 1983 and behind systems from DeepMind's A3C to PPO-based LLM training.
Actor-critic reinforcement learning
Actor-critic reinforcement learning is a machine learning method in which an actor parameterizes a policy and a critic estimates state values, combining low variance with direct policy optimization.
Actoz Soft
Actoz Soft (액토즈소프트) is a South Korean video game developer and publisher, founded in Seoul in 1996, known for early Korean MMORPGs including the Legend of Mir series and LaTale.
Acunetix
Acunetix is an automated web application security testing tool sold by Invicti that audits websites for vulnerabilities such as SQL injection and cross-site scripting, pioneered in 2005.
Ad blocking
Ad blocking, done with ad blockers, is software, usually a browser extension, that stops advertisements from loading on websites, speeding up browsing, reducing tracking, and cutting advertising revenue.
Ad hoc On-Demand Distance Vector routing
Ad hoc On-Demand Distance Vector (AODV) routing is a reactive routing protocol for mobile ad hoc networks, specified as RFC 3561 by Perkins, Belding-Royer, and Das in 2003.
Ada (programming language)
Ada, also called the Ada language, is a statically typed programming language developed for the United States Department of Defense in 1979 for reliable embedded systems.
Ada Lovelace
Ada Lovelace, born Augusta Ada Byron, was an English mathematician whose 1843 Notes on Babbage's Analytical Engine included what is often called the first published computer program.
Ada Lovelace Institute
The Ada Lovelace Institute is an independent research institute in London, established by the Nuffield Foundation in 2018 to study the ethical and social implications of data and AI.
AdaBoost
AdaBoost is a machine-learning ensemble algorithm introduced by Yoav Freund and Robert Schapire that combines weak classifiers into a strong one; their 1997 paper won the 2003 Gödel Prize.
AdaDelta
AdaDelta is an adaptive learning rate method for gradient descent, proposed by Matthew D. Zeiler in December 2012, that eliminates the need for a hand-tuned global learning rate.
AdaGrad
AdaGrad is a gradient-based optimization algorithm that assigns each parameter its own learning rate, introduced by John Duchi, Elad Hazan, and Yoram Singer in 2010 for online learning.
ADALINE
ADALINE, short for ADaptive LInear NEuron, is an early artificial neuron introduced in 1960 by Bernard Widrow and Marcian Hoff at Stanford, trained by the Widrow-Hoff delta rule.
AdaLoRA
AdaLoRA (Adaptive LoRA) is a parameter-efficient fine-tuning method for large language models that allocates a fixed parameter budget by importance rather than uniformly, published at ICLR 2023.
Adam D'Angelo
Adam D'Angelo, born in 1984, is an American technology executive who co-founded Quora in 2009 and serves as its CEO; he was Facebook's first chief technology officer.
Adam Guild
Adam Guild is an American technology entrepreneur who co-founded Owner.com, a software platform that lets independent restaurants take online orders directly instead of through commission-charging delivery marketplaces.
Adam Mosseri
Adam Mosseri (אדם מוסרי) is an American technology executive who has been head of Instagram since 2018, after previously running product for Facebook's News Feed and overseeing the Threads app.
Adam optimizer
Adam, or adaptive moment estimation, is a first-order gradient-based optimization algorithm introduced by Diederik P. Kingma and Jimmy Ba in 2014, widely used for training deep learning models.
AdamW
AdamW is the Adam stochastic optimizer with its weight decay decoupled from the adaptive gradient update, introduced by Loshchilov and Hutter in 2017 and now the default for training large language models.
