ENSCO, Inc. is a privately held American technology company in Vienna, Virginia, founded in 1969, best known for its railway track inspection subsidiary ENSCO Rail.
Ensembl
Ensembl is a public genome browser and annotation database based at EMBL-EBI in the United Kingdom, founded in 1999 to automatically annotate genomes with open-access gene, variation, and comparative data.
Ensemble cast
Ensemble cast: a group of principal actors sharing roughly equal narrative importance with no single lead, in film, TV, or theater. Also called ensemble casting; distinguished from star vehicles, supporting casts, and anthologies by the load-bearing test of removing a member.
Ensemble clustering
Ensemble clustering, also called consensus clustering, is a machine learning method that combines multiple clusterings of the same data into a single consensus partition, improving quality and robustness.
Ensemble effect in single-atom alloys
The ensemble effect in single-atom alloys is the principle that a catalytic reaction may require a specific number of adjacent atoms of one metal, which dilution controls.
Ensemble empirical mode decomposition
Ensemble empirical mode decomposition (EEMD) is a noise-assisted signal-processing method introduced by Zhaohua Wu and Norden Huang in 2009 that cures EMD's mode mixing by averaging many noise-added runs.
Ensemble forecasting
Ensemble forecasting is a weather and climate prediction method that runs a numerical model many times with varied initial conditions, yielding probabilities instead of a single forecast.
Ensemble Kalman filter
The ensemble Kalman filter (EnKF) is a Monte Carlo implementation of the Kalman filter for high-dimensional, nonlinear state estimation, proposed by Geir Evensen in 1994 for ocean modeling.
Ensemble learning
Ensemble learning, also called ensemble methods, is a machine learning approach that combines predictions from multiple models into one, using methods like bagging, boosting, and stacking.
Ensemble Modern
Ensemble Modern is a German contemporary classical ensemble of eighteen soloists based in Frankfurt am Main, founded in 1980 and regarded among the leading new music ensembles worldwide.
Ensemble of the Ferapontov Monastery
Ensemble of the Ferapontov Monastery (Ансамбль Ферапонтова монастыря): 15th-17th century Russian Orthodox monastic complex in Vologda region, founded 1398, UNESCO World Heritage site since 2000, with Dionisy's fully preserved 1502 cathedral frescoes.
Ensemble regression
Ensemble regression is a machine learning method that combines several regression models into one predictor, typically by averaging, so that individual errors partially cancel; bagging and boosting are the classical ways of building it.
Ensemble simulation
An ensemble simulation runs a numerical model many times with slightly different initial conditions, parameters, or formulations, so the spread among runs estimates forecast uncertainty, underpinning operational weather and climate prediction since 1992.
Ensemble transform Kalman filter
The ensemble transform Kalman filter (ETKF) is a deterministic square-root Kalman filter, introduced in 2001, that assimilates observations into a forecast ensemble without perturbing observations.
