Interaction matrix
The interaction matrix, also called the image Jacobian, is the matrix in image-based visual servoing that maps camera velocity to the rate of change of image features such as points.
Interaction nets
Interaction nets are a graphical model of computation, introduced by Yves Lafont in 1990, where computation is local rewriting of agents connected by wires, generalizing proof nets.
Interaction of two metal-oxo (I2M) mechanism
The interaction of two metal-oxo (I2M) mechanism is a water oxidation pathway in which two metal–oxo units couple to an M–O–O–M peroxide that releases O2, contrasting with water nucleophilic attack.
Interaction picture
The interaction picture, also called the Dirac picture, is a formulation of quantum dynamics where states evolve under the perturbation and operators under the solvable part.
Interaction testing (statistics)
Interaction testing in statistics determines whether the effect of one variable on an outcome depends on the level of another, usually via a product term in regression.
Interactive Brokers
Interactive Brokers Group, Inc. is an automated global electronic broker headquartered in Greenwich, Connecticut, founded by Thomas Peterffy in 1993 and serving over 5 million accounts in more than 200 countries.
Interactive Disassembler
The Interactive Disassembler, sold as IDA Pro, is a programmable disassembler and debugger developed by Hex-Rays in Liège, Belgium, and created by Ilfak Guilfanov, supporting over 60 processor families.
Interactive fiction
Interactive fiction (IF), or text adventure, is a game genre told primarily through text, advanced by typed parser commands or on-screen choices. Founded on Colossal Cave Adventure (1976) and Infocom's Zork; modern tools include Twine, Inform, and Ink.
Interactive genetic algorithm
An interactive genetic algorithm is a genetic algorithm in which a human user evaluates candidate solutions instead of a fitness function, applied to art, music, and design tasks.
Interactive machine learning
Interactive machine learning (IML) is an approach in which users iteratively build and refine a model through rapid, focused, incremental cycles of input and review.
Interactive machine translation
Interactive machine translation (IMT) is a mode of computer-assisted translation in which a human translator and a machine translation system build the target text together, with the system re-predicting after each edit.
Interactive proof system
An interactive proof system is a protocol in which a computationally limited verifier checks a mathematical statement via randomized back-and-forth messages with an all-powerful prover.
Interactive Strength, Inc.
Interactive Strength Inc. (Nasdaq: TRNR), doing business as Forme, is a fitness-technology company founded in 2017 that makes connected fitness equipment and went public in April 2023.
Interactive theatre
Interactive theatre (also medspilsteater, Mitspieltheater) is live performance in which audience members participate, choose, or co-create, breaking the actor-spectator barrier; spans forum, playback, participatory, immersive, and digital forms.
Interactive Ventilatory Support
Interactive Ventilatory Support (MeSH D059725), also called proportional modes: mechanical ventilation matching patient effort breath-by-breath, chiefly proportional assist ventilation (PAV/PAV+) and neurally adjusted ventilatory assist (NAVA), used to reduce asynchrony and aid weaning versus pressure support ventilation.
Interactive voice response
Interactive voice response, known as IVR or an audio response unit, is a computerized phone system where callers interact with menus using keypads or speech.
Interactive whiteboard
An interactive whiteboard is a large touch-sensitive board connected to a computer and projector, first commercialized by SMART Technologies in 1991 and common in classrooms.
Interactivity
Interactivity in web user interfaces is the property of content that responds to user input by changing state or performing an action, resting on keyboard operability, DOM events, and user activation.
Interahamwe
Interahamwe, Kinyarwanda 'those who attack together': Hutu militia of Rwanda's MRND party, founded early 1990s, main civilian killing force of the 1994 genocide against the Tutsi; remnants later formed the FDLR in Congo.
Interamerican Society of Cardiology
Interamerican Society of Cardiology (SIAC/IASC), founded 1944 in Mexico City by Ignacio Chávez, is a federation of 28 national cardiology societies of the Americas plus Spain, with 40,000+ cardiologists, PAHO relations since 2012, annual congresses, and the journal RIAC.
Interamna Lirenas
Interamna Lirenas, a Roman town near Pignataro Interamna in southern Lazio, founded as a Latin colony in 312 BC with 4,000 colonists; re-appraised by Cambridge archaeologists as a resilient market town, not a backwater.
Interamnium
Interamnium (Nteramnio on the Tabula Peutingeriana) was a Roman road station on the Via Popilia in the Sybaris valley, Calabria, near modern San Lorenzo del Vallo; located near the Esaro-Coscile confluence, attested only by the Geographer of Ravenna.
Interatomic Coulombic decay
Interatomic Coulombic decay (ICD) is a nonlocal electronic decay process in which an excited atom or molecule ionizes a neighboring one, emitting a low-energy electron.
Interaural time difference
Interaural time difference (ITD): the arrival-time difference of a sound at the two ears, the dominant cue for horizontal sound localization at low frequencies, encoded by coincidence-detecting MSO neurons, with human sensitivity near 10 microseconds and a maximum near 763 microseconds.
InteraXon
InteraXon is a Canadian neurotechnology company founded in Toronto in 2007 that makes the Muse line of consumer EEG headbands for meditation, neurofeedback, and sleep tracking.
Interball
Interball (ИНТЕРБОЛ) was a Russian-led program of four spacecraft in two pairs, launched in 1995 and 1996, that studied plasma processes in Earth's magnetosphere and solar wind.
Interbank lending market
The interbank lending market is where banks and other financial institutions lend unsecured funds to one another, reshaped since the 2007–09 financial crisis and the failure of LIBOR.
Interbreeding between archaic and modern humans
Interbreeding between archaic and modern humans: admixture with Neanderthals and Denisovans. Non-Africans carry ~2% Neanderthal DNA, Oceanians up to ~6% Denisovan; admixture dated ~45–49 ka.
