Exploration

Exploration: traveling to unfamiliar places to learn about them, and, in decision science, the explore-exploit trade-off between unknown and known options. Covers the Age of Exploration, Zheng He, bandit models, and neural findings.

Exploration in reinforcement learning

Exploration in reinforcement learning is the problem of how a trial-and-error agent balances trying new actions against repeating ones that already look good, especially in sparse-reward settings.

Exploration Method of Love (爱的勘探法)

Exploration Method of Love (爱的勘探法), also known as Mo Da Wei De Mi Mi, is a 2023 Mango TV Chinese urban romance drama, 22 episodes, directed by Qiu Yu, starring Song Yanfei and Gao Hanyu, adapted from Mo Li's novel.

Exploration of Jupiter

The exploration of Jupiter is the study of the planet and its moons by spacecraft, beginning with Pioneer 10's 1973 flyby and continuing today with NASA's Juno orbiter.

Exploration of Krubera Cave

Krubera Cave, also called Voronja, is a cave in Abkhazia that became the deepest known cave on Earth in 2001, first explored past 2,000 m in 2004.

Exploration of Lechuguilla Cave

The exploration of Lechuguilla Cave, in Carlsbad Caverns National Park, New Mexico, transformed a small dead-end pit into one of the world's longest caves after a 1986 breakthrough.

Exploration of Mars

Exploration of Mars, also called Martian exploration, is the robotic and, prospectively, human investigation of the planet by spacecraft, led by NASA since the Mariner flybys of the 1960s.

Exploration of North America

Exploration of North America: European voyages from the Norse landings at L'Anse aux Meadows (Vinland, AD 1021) through Columbus, Spanish and French expeditions, colonial settlement, and the Lewis and Clark crossing.

Exploration of Sistema Sac Actun

Exploration of Sistema Sac Actun, a flooded cave near Tulum, Mexico, began in 1987; after a 2018 connection with Dos Ojos it briefly ranked as the world's longest underwater cave.

Exploration of the Moon

The exploration of the Moon, also known as Moon exploration, is the study of Earth's natural satellite by robotic spacecraft and crewed missions, ongoing since 1959.

Exploratorium

The Exploratorium is a museum of science, art, and human perception in San Francisco, founded by physicist Frank Oppenheimer in 1969 and known for hands-on, interactive exhibits.

Exploratory causal analysis

Exploratory causal analysis, also known as causal discovery or data causality, uses observational data to learn the causal structure of a system of variables, typically as a causal graph.

Exploratory data analysis

Exploratory data analysis, also called explorative data analysis, is a statistical approach that examines data first with descriptive statistics and graphs before hypothesis testing, named by John Tukey in 1977.

Exploratory factor analysis

Exploratory factor analysis (EFA) is a multivariate statistical method that models correlations among observed variables as the shared influence of a smaller number of unobserved common factors, without imposing a factor structure in advance.

Exploratory graph analysis

Exploratory graph analysis (EGA) is a network psychometrics method that estimates the number of dimensions in data via community detection on a regularized correlation network.

Exploratory laparotomy

Exploratory laparotomy is an open surgical exploration of the abdomen through a midline incision, both diagnostic and therapeutic, most often performed as an emergency for bleeding, perforation, or trauma.

Exploratory research

Exploratory research is a mode of scientific inquiry used when a problem is loosely defined or little studied, generating concepts and hypotheses rather than testing them.

Exploratory sequential mixed methods design

The exploratory sequential mixed methods design is a research design that runs a qualitative phase first, then a quantitative phase to test or generalize the findings.

Exploratory structural equation modeling

Exploratory structural equation modeling (ESEM) is a statistical framework, introduced by Tihomir Asparouhov and Bengt Muthén in 2009, that combines exploratory factor analysis with the confirmatory machinery of structural equation modeling.

Exploratory surgery

Exploratory surgery is a diagnostic operation in which a surgeon opens a body cavity, usually the abdomen, to inspect organs directly when imaging has not produced a diagnosis.

Exploratory testing

Exploratory testing is a software testing approach where testers design, execute, and evaluate tests simultaneously, letting each result shape the next test instead of following a script.

Explorer (Rocket Lab)

Explorer is Rocket Lab's configurable interplanetary spacecraft platform for missions to Mars, Venus, the Moon, and deep space, with flight heritage from NASA's 2022 CAPSTONE lunar mission.

Explorer 1

Explorer 1 was the first successful United States satellite, launched January 31, 1958 from Cape Canaveral; its cosmic ray instrument led to the discovery of the Van Allen radiation belts.

Explorer of the Seas

Explorer of the Seas is a Voyager-class cruise ship built for Royal Caribbean International in 2000, among the largest passenger ships of its time, with an onboard oceanographic laboratory.

Explorer Pipeline

Explorer Pipeline is an American common-carrier pipeline transporting gasoline, diesel, and jet fuel from Gulf Coast refineries to Midwest markets, formed in 1967 and headquartered in Tulsa.
