REST
REST (Representational State Transfer) is an architectural style for distributed hypermedia systems, defined by Roy Fielding in a 2000 dissertation at UC Irvine and embodied by the Web and HTTP.
ReST / ReST-EM
ReST (Reinforced Self-Training) is a post-training method for language models, introduced by Gulcehre et al. at DeepMind in 2023, that fine-tunes on reward-filtered samples of its own outputs.
Rest area
A rest area is a public roadside facility on freeways, providing parking, restrooms, and picnic amenities so drivers can take breaks without leaving the highway.
REST Assured
REST Assured is an open-source Java domain-specific language for simplifying the testing of REST web services, started by Johan Haleby at Jayway in 2010 and licensed under Apache 2.0.
ReStore (exosuit)
The ReStore, marketed as the ReStore Exo-Suit, is a soft robotic exosuit that assists the paretic ankle during walking in therapist-supervised stroke rehabilitation, FDA-cleared in 2019.
Restoring force model
A restoring force model is a mathematical relation between a structural member's restoring force and its deformation, used to represent hysteretic behavior in nonlinear seismic response analysis.
Restricted Boltzmann machine
A restricted Boltzmann machine (RBM) is a generative neural network of stochastic units in two layers, trained by contrastive divergence and used to build deep belief networks.
Restrictions on cell phone use while driving in the United States
Restrictions on cell phone use while driving in the United States are a patchwork of state and federal laws, from texting bans in nearly all states to hands-free requirements.
Restrictor plate
A restrictor plate, also called an air restrictor, is a metal plate with small holes in an engine's air intake that caps horsepower and top speed, best known from NASCAR.
ReStructuredText
reStructuredText (reST) is a plaintext markup language designed to be readable in raw and processed forms, created by David Goodger in 2001 and serving as the default markup for Sphinx and Python's documentation.
Resurs-F
Resurs-F (Ресурс-Ф, "Resource") was a Soviet and Russian family of film-return Earth observation satellites built by TsSKB in Samara, photographing Earth in visible and near-infrared light from 1979 to 1999.
Resyone
Resyone is a Panasonic rise-assisting nursing care robot in which half of an electric care bed detaches and functions as a wheelchair, moving a person from bed without lifting.
Retained austenite
Retained austenite is austenite in quenched steel that fails to transform to martensite and stays untransformed at room temperature because cooling never reaches the martensite finish temperature.
Retaining wall
A retaining wall is a structure built to hold back soil or other material at a difference in elevation, resisting the lateral pressure of the ground behind it.
Retargeting human motion to humanoids
Retargeting human motion to humanoids converts captured human motion into trajectories a humanoid robot with a different body can execute, the first stage in teleoperation and imitation learning.
Rete Ferroviaria Italiana
Rete Ferroviaria Italiana (RFI) is the company of the FS Italiane Group that manages Italy's national railway infrastructure, founded on 1 July 2001 and based in Rome.
Retention basin
A retention basin, also known as a retention pond, wet pond, or stormwater management pond, is a pond that permanently holds water and treats urban stormwater runoff.
Retentive Network
Retentive Network (RetNet) is a large language model architecture proposed by Microsoft Research in July 2023, which replaces multi-head self-attention with a retention mechanism supporting parallel, recurrent, and chunkwise computation.
Rethink Robotics
Rethink Robotics was an American collaborative-robotics company founded in Boston in 2008 by Rodney Brooks, best known for the Baxter and Sawyer factory robots, and closed in 2018.
Rethmann
Rethmann, also known as the Rethmann Group, is a German family-owned holding company founded in Selm in 1934, parent of REMONDIS, Rhenus, SARIA, and Transdev.
Reticle
A reticle is a patterned glass or quartz master plate used in photolithography to print one layer of an integrated circuit onto a wafer, broadly interchangeable with the term photomask.
Retiming (digital circuits)
Retiming is a sequential circuit optimization technique that relocates registers across combinational logic, reducing clock period or register count while preserving the circuit's functional behavior.
Retina display
Retina display, Apple's marketing term for screens whose pixels are too small to see individually at typical viewing distance, was introduced with the iPhone 4 in June 2010.
Retinal implant
A retinal implant is a medical device that restores partial vision to people blinded by retinitis pigmentosa or macular degeneration by electrically stimulating surviving retinal neurons.
RetinaNet
RetinaNet is a one-stage object detection model introduced in 2017 by Tsung-Yi Lin and colleagues at Facebook AI Research, known for focal loss, which down-weights easy background examples during training.
Retort carbon
Retort carbon, also called gas carbon, is a dense, hard carbon deposit that forms on retort walls during the destructive distillation of coal for town gas.
Retractable bridge
A retractable bridge, also called a thrust or traversing bridge, is a movable bridge whose deck rolls back from the navigation gap rather than lifting, swinging, or curling aside.
Retransmission
Retransmission is the mechanism by which a network protocol resends data lost or corrupted in transit, restoring reliable delivery; TCP and QUIC rely on it for reliability.
Retrievability
Retrievability is the ability in principle to recover radioactive waste or entire waste packages emplaced in a geological disposal repository; technically practicable for hundreds of years, and a legal requirement in some countries.
Retrieval head
A retrieval head is an attention head in a transformer language model that retrieves relevant information from long input contexts; the concept was introduced in 2024.
