Human-in-the-loop
Human-in-the-loop (HITL) is used in multiple contexts. It can be defined as a model requiring human interaction. HITL is associated with modeling and simulation (M&S) in the live, virtual, and constructive taxonomy. HITL along with the related human-on-the-loop are also used in relation to lethal autonomous weapons. Further, HITL is used in the context of machine learning. Machine learning In machine learning, HITL is used in the sense of humans aiding the computer in making the correct decisions in building a model. HITL improves machine learning over random sampling by selecting the most critical data needed to refine the model. Simulation In simulation, HITL models may conform to human factors requirements as in the case of a mockup. In this type of simulation a human is always part of the simulation and consequently influences the outcome in such a way that is difficult if not impossible to reproduce exactly. HITL also readily allows for the identification of problems and re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Military Robots
Military robots are autonomous robots or remote-controlled mobile robots designed for military applications, from transport to search & rescue and attack. Some such systems are currently in use, and many are under development. The difference between military robots and military drones is unclear as of 2025: some say that lethal autonomous weapons are robots whereas others describe “fully autonomous military drones”. History Broadly defined, military robots date back to World War II and the Cold War in the form of the German Goliath tracked mines and the Soviet teletanks. The introduction of the MQ-1 Predator drone was when "CIA officers began to see the first practical returns on their decade-old fantasy of using aerial robots to collect intelligence". The use of robots in warfare, although traditionally a topic for science fiction, is being researched as a possible future means of fighting wars. Already several military robots have been developed by various ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reinforcement Learning From Human Feedback
In machine learning, reinforcement learning from human feedback (RLHF) is a technique to AI alignment, align an intelligent agent with human preferences. It involves training a reward model to represent preferences, which can then be used to train other models through reinforcement learning. In classical reinforcement learning, an intelligent agent's goal is to learn a function that guides its behavior, called a reinforcement learning#Policy, policy. This function is iteratively updated to maximize rewards based on the agent's task performance. However, explicitly defining a reward function that accurately approximates human preferences is challenging. Therefore, RLHF seeks to train a "reward model" directly from human feedback. The reward model is first trained in a supervised learning, supervised manner to predict if a response to a given prompt is good (high reward) or bad (low reward) based on ranking data collected from human labeled data, annotators. This model then serves a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flight Simulators
A flight simulator is a device that artificially re-creates aircraft flight and the environment in which it flies, for pilot training, design, or other purposes. It includes replicating the equations that govern how aircraft fly, how they react to applications of flight controls, the effects of other aircraft systems, and how the aircraft reacts to external factors such as air density, turbulence, wind shear, cloud, precipitation, etc. Flight simulation is used for a variety of reasons, including flight training (mainly of pilots), the design and development of the aircraft itself, and research into aircraft characteristics and control handling qualities. The term "flight simulator" may carry slightly different meaning in general language and technical documents. In past regulations, it referred specifically to devices which can closely mimic the behavior of aircraft throughout various procedures and flight conditions. In more recent definitions, this has been named "full fli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Military Terminology
Military terminology refers to the terminology, terms and language of military organizations, military personnel, personnel, and military doctrine. Much like other forms of corporate jargon, military terminology is distinguishable from colloquial language by its use of new or repurposed words and phrases typically only understandable by current and former members of the military or associated companies and agencies. Common understanding The operational pressure for uniform understanding has developed since the early 20th century with the importance of Joint warfare, joint operations between different services (army, navy, air force) of the same country. International alliances and operations, including peacekeeping, have added additional complexity. For example, the NATO alliance now maintains a large dictionary of common terms for use by member countries. Development work is also taking place between NATO and Russia on common terminology for extended air defence, in English, Fre ...

Military Technology
Military technology is the application of technology for use in warfare. It comprises the kinds of technology that are distinctly military in nature and not civilian in application, usually because they lack useful or legal civilian applications, or are dangerous to use without appropriate military training. The line is porous; military inventions have been brought into civilian use throughout history, with sometimes minor modification if any, and civilian innovations have similarly been put to military use. Military technology is usually researched and developed by scientists and engineers specifically for use in battle by the armed forces. Many new technologies came as a result of the military funding of science. On the other hand, the theories, strategies, concepts and doctrines of warfare are studied under the academic discipline of military science. Armament engineering is the design, development, testing and lifecycle management of military weapons and systems. It draws ...

Machine Learning
Machine learning (ML) is a field of study in artificial intelligence concerned with the development and study of Computational statistics, statistical algorithms that can learn from data and generalise to unseen data, and thus perform Task (computing), tasks without explicit Machine code, instructions. Within a subdiscipline in machine learning, advances in the field of deep learning have allowed Neural network (machine learning), neural networks, a class of statistical algorithms, to surpass many previous machine learning approaches in performance. ML finds application in many fields, including natural language processing, computer vision, speech recognition, email filtering, agriculture, and medicine. The application of ML to business problems is known as predictive analytics. Statistics and mathematical optimisation (mathematical programming) methods comprise the foundations of machine learning. Data mining is a related field of study, focusing on exploratory data analysi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ethics Of Science And Technology
Ethics is the philosophical study of moral phenomena. Also called moral philosophy, it investigates normative questions about what people ought to do or which behavior is morally right. Its main branches include normative ethics, applied ethics, and metaethics. Normative ethics aims to find general principles that govern how people should act. Applied ethics examines concrete ethical problems in real-life situations, such as abortion, treatment of animals, and business practices. Metaethics explores the underlying assumptions and concepts of ethics. It asks whether there are objective moral facts, how moral knowledge is possible, and how moral judgments motivate people. Influential normative theories are consequentialism, deontology, and virtue ethics. According to consequentialists, an act is right if it leads to the best consequences. Deontologists focus on acts themselves, saying that they must adhere to duties, like telling the truth and keeping promises. Virtue et ...

MIM-104 Patriot
The MIM-104 Patriot is a mobile interceptor missile surface-to-air missile (SAM) system, the primary such system used by the United States Army and several allied states. It is manufactured by the U.S. defense contractor Raytheon and derives its name from the radar component of the weapon system. The AN/MPQ-53 at the heart of the system is known as the "Phased Array Tracking Radar to Intercept on Target", which is a backronym for "Patriot". In 1984, the Patriot system began to replace the Nike Hercules system as the U.S. Army's primary high to medium air defense (HIMAD) system and the MIM-23 Hawk system as the U.S. Army's medium tactical air defense system. In addition to these roles, Patriot has been given a function in the U.S. Army's anti-ballistic missile (ABM) system. , the system is expected to stay fielded until at least 2040. Patriot uses an advanced aerial interceptor missile and high-performance radar systems. Patriot was developed at Redstone Arsenal in Huntsville, A ...

Humanistic Intelligence
Humanistic Intelligence (HI) is defined, in the context of wearable computing, by Marvin Minsky, Ray Kurzweil, and Steve Mann, as follows: Humanistic Intelligence Iis intelligence that arises because of a human being in the feedback loop of a computational process, where the human and computer are inextricably intertwined. When a wearable computer embodies HI and becomes so technologically advanced that its intelligence matches our own biological brain, something much more powerful emerges from this synergy that gives rise to superhuman intelligence within the single “cyborg” being. More generally (beyond only wearable computing), HI describes the creation of intelligence that results from a feedback loop between a computational process and a human being, where the human and computer are inextricably intertwined. In the field of human-computer interaction (HCI) it has been common to think of the human and computer as separate entities. HCI emphasizes this separateness ...

Human Rights Watch
Human Rights Watch (HRW) is an international non-governmental organization that conducts research and advocacy on human rights. Headquartered in New York City, the group investigates and reports on issues including War crime, war crimes, crimes against humanity, Child labour, child labor, torture, human trafficking, and Women's rights, women's and LGBTQ rights. It pressures governments, policymakers, companies, and individual abusers to respect human rights, and frequently works on behalf of refugees, children, migrants, and political prisoners. The organization was founded in 1978 as Helsinki Watch, whose purpose was to monitor the Soviet Union's compliance with the 1975 Helsinki Accords. Its separate global divisions merged into Human Rights Watch in 1988. The group publishes annual reports on about 100 countries with the goal of providing an overview of the worldwide state of human rights. In 1997, HRW shared the Nobel Peace Prize as a founding member of the International C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bonnie Docherty
Bonnie is a Scottish given name and is sometimes used as a descriptive reference, as in the Scottish folk song, My Bonnie Lies over the Ocean or Bonnie Dundee about John Graham, 7th Laird of Claverhouse. It comes from the Scots language word "bonnie" (handsome, pretty, attractive), or the French bonne (good). That is in turn derived from the Latin word "bonus" (good). The name can also be used as a pet form of Bonita. Usage The name has been in use, primarily in the Anglosphere, since the 1800s. It has been ranked among the 50 most popular names for newborn girls in the United Kingdom since 2020 and had been rising in popularity for British girls since the 1990s. It was among the 1,000 most used names for newborn girls in the United States between 1880 and 2003, reaching the height of popularity between 1928 and 1966, when it was ranked among the 100 most popular names for newborn American girls. It was also ranked among the 1,000 most popular names for newborn American boys bet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital Puppetry
Digital puppetry is the manipulation and performance of digitally animated 2D or 3D figures and objects in a virtual environment that are rendered in real-time by computers. It is most commonly used in filmmaking and television production but has also been used in interactive theme park attractions and live theatre. The exact definition of what is and is not digital puppetry is subject to debate among puppeteers and computer graphics designers, but it is generally agreed that digital puppetry differs from conventional computer animation in that it involves performing characters in real-time, rather than animating them frame by frame. Digital puppetry is closely associated with character animation, motion capture technologies, and 3D animation, as well as skeletal animation. Digital puppetry is also known as virtual puppetry, performance animation, living animation, aniforms, live animation and real-time animation (although the latter also refers to animation generated by com ...
