Dolma
Dolma is an openly licensed English pretraining corpus for large language models, created by the Allen Institute for AI in 2023 to train its OLMo model family.
Dolmabahçe Palace
Dolmabahçe Palace (Dolmabahçe Sarayı) is a former Ottoman imperial palace on the European shore of the Bosphorus in Istanbul, built between 1843 and 1856, where Atatürk died in 1938.
Dolna Odra power station
The Dolna Odra power station (Elektrownia Dolna Odra) is a power plant at Nowe Czarnowo near Gryfino, north-western Poland, operated by PGE and converted from coal to gas.
Dolos (breakwater)
The dolos is a concrete armor unit shaped like a ship's anchor, invented in South Africa in 1963 and placed on breakwaters worldwide to dissipate wave energy economically.
Dolphin fine-tunes
Dolphin fine-tunes are community-modified versions of open-weight language models, created by Eric Hartford, in which the base model's refusal behavior is removed from the weights; they power 30% of identified uncensored GitHub applications.
Dolphin Oil and Gas Field
The Dolphin Oil and Gas Field, also called the Dolphin Gas Project, pipes natural gas from Qatar's offshore North Field to the UAE and Oman, starting supply in July 2007.
Dolphin Qatar–UAE Natural Gas Pipeline
The Dolphin Qatar–UAE Natural Gas Pipeline is a 364-kilometer subsea pipeline carrying 2 billion cubic feet of gas daily from Ras Laffan, Qatar, to Taweelah, Abu Dhabi, since 2007.
Dolphin-class submarine
The Dolphin class (Hebrew: הצוללות מסדרת דולפין) is a series of diesel-electric submarines built by Howaldtswerke-Deutsche Werft in Kiel, Germany, for the Israeli Navy, largely German-financed, serving since 1999.
Dolt (database)
Dolt is an open-source, MySQL-compatible SQL database with Git-style version control (branch, merge, diff, clone) built on content-addressed Prolly Trees; launched 2019 by DoltHub, with Doltgres for Postgres and Dolt 2.0 in 2026.
Dom Luís I Bridge
The Dom Luís I Bridge (Ponte Dom Luís I) is an 1886 double-deck iron arch bridge over the Douro River between Porto and Vila Nova de Gaia, Portugal.
Domain adaptation
Domain adaptation is a machine learning setting in which a model trained on labeled data from one distribution is adapted to predict accurately on a different but related distribution.
Domain adaptation network
A domain adaptation network is a neural network trained on labeled source and unlabeled target data so its features transfer across the domain shift, enabling target-domain classification.
Domain analysis
Domain analysis is a software engineering process that identifies and organizes information across similar systems in a domain, making it reusable when building new products.
Domain generation algorithm
A domain generation algorithm (DGA) is an algorithm in malware that generates many domain names, letting infected machines find command-and-control servers that blacklisting cannot block.
Domain name
A domain name is a human-readable, hierarchical identifier, such as icann.org, registered in the Domain Name System since 1983 and mapped to the IP addresses of Internet hosts.
Domain name registrar
A domain name registrar, also called a domain registrar, is a company accredited by ICANN to register and maintain domain names for customers, who manage settings through it.
Domain Name System
The Domain Name System (DNS), also called DNS, is the Internet's hierarchical, distributed database translating domain names into IP addresses, defined by RFCs 1034 and 1035 in 1987.
Domain Name System Security Extensions
The Domain Name System Security Extensions (DNSSEC) are Internet standards that add cryptographic authentication and integrity to DNS, preventing attackers from forging responses and redirecting users.
Domain randomization
Domain randomization is a sim-to-real transfer technique, introduced in 2017 OpenAI-associated papers, that randomizes simulation textures, lighting, and physics so policies trained in simulation transfer to real robots without real-world calibration.
Domain validation
Domain validation (DV), also called domain control validation, is the minimum check a certificate authority performs before issuing a TLS certificate, verifying control of the domain but not the applicant's identity.
Domain-adaptive object detection
Domain-adaptive object detection adapts a detector trained on labeled source images to a target domain whose data distribution differs, using unlabeled target images, mainly through adversarial feature alignment and self-training with pseudo-labels.
Domain-adversarial neural network
A domain-adversarial neural network (DANN) is a neural network for unsupervised domain adaptation, introduced by Yaroslav Ganin and Victor Lempitsky in 2014, that uses a gradient reversal layer to make features indistinguishable across domains.
Domain-adversarial training of neural networks
Domain-adversarial training of neural networks (DANN) is an unsupervised domain adaptation technique introduced by Ganin and Lempitsky in 2014, which uses a gradient reversal layer to learn domain-invariant features.
Domain-driven design
Domain-driven design is an approach to software development that centers on a model of the business domain rather than technical layers, named after Eric Evans's 2003 book.
Domain-specific language
A domain-specific language, also called a little language or mini-language, is a programming language targeted at one kind of problem, examples including SQL, CSS, and regular expressions.
DomainKeys Identified Mail
DomainKeys Identified Mail (DKIM) is an email authentication method in which the sending organization cryptographically signs a message, letting receivers verify its origin and integrity.
Dombarovskiy
Dombarovskiy, also written Dombarovsky and known as the Yasny launch site, is a Russian strategic missile base and space launch site in Orenburg Oblast, near the Kazakhstan border.
Dome
A dome is a rounded roof or vault shaped like the upper half of a sphere, whose curved shell carries its weight to the ground without internal supports.
Dome car
A dome car is a railroad passenger car with a raised, glass-enclosed observation compartment in the roof, offering panoramic views; the type originated in the United States in the mid-1940s.
Dome of the Rock (قبة الصخرة)
The Dome of the Rock (قبة الصخرة) is an Islamic shrine in Jerusalem, begun in 691–692 by the Umayyad caliph Abd al-Malik over a sacred rock on the Temple Mount.
