An in-place algorithm is an algorithm that uses only constant extra space beyond its input, so algorithms like heapsort and quicksort sort without an auxiliary array.
In-situ reactive additive manufacturing of titanium matrix composites
In-situ reactive additive manufacturing of titanium matrix composites (TMCs) builds titanium parts by 3D printing while chemical reactions form TiB whiskers and TiC reinforcements in the melt pool.
In-situ recovery
In-situ recovery, also called in-situ leaching, is a uranium mining method that dissolves ore underground with chemically treated solution and pumps the uranium to the surface without excavation.
In-system programming
In-system programming (ISP), also called in-circuit or on-board programming, writes firmware, configuration data, or bitstreams to a device while it is soldered on its printed circuit board, using interfaces such as JTAG, SPI, and SWD.
in-toto
in-toto is a framework for software supply chain security that cryptographically records each step and verifies execution matched a plan, created in 2015 at NYU.
In-vessel retention
In-vessel retention, also called in-vessel melt retention, is a severe accident management strategy that keeps molten reactor core material inside the vessel by cooling it externally with water.
In-wheel motor
An in-wheel motor (IWM), also called a hub motor, is an electric traction motor built inside a vehicle's wheel hub, first used on Ferdinand Porsche's Lohner-Porsche in 1900.

An incendiary device, also called an incendiary weapon, is a weapon or munition primarily designed to set fires or cause burn injuries, including flame throwers, napalm, and thermite bombs.
Inception network
The Inception network is a family of convolutional neural network architectures for image classification, introduced in 2014; its GoogLeNet version won ILSVRC 2014 by running filters of several sizes in parallel.
Inception score
The Inception score (IS) is a metric for evaluating generative image models, measuring the confidence and diversity of a pretrained Inception classifier's predictions on generated images.
