The tempest prognosticator, also known as the leech barometer, is a 19th-century invention by George Merryweather in which leeches are used in a barometer. The twelve leeches are kept in small bottles inside the device; when they become agitated by an approaching storm, they attempt to climb out of the bottles and trigger a small hammer which ...
His best-known invention was the Tempest Prognosticator—a weather predicting device also called "The Leech Barometer". [2] It consists of twelve glass bottles containing leeches, which, when disturbed by the atmospheric conditions preceding a storm, climb upwards, triggering a small whalebone hammer which rings a bell.
An example of 500 mbar geopotential height and absolute vorticity prediction from a numerical weather prediction model Main article: Numerical weather prediction The basic idea of numerical weather prediction is to sample the state of the fluid at a given time and use the equations of fluid dynamics and thermodynamics to estimate the state of ...
Prediction by partial matching (PPM) is an adaptive statistical data compression technique based on context modeling and prediction. PPM models use a set of previous symbols in the uncompressed symbol stream to predict the next symbol in the stream. PPM algorithms can also be used to cluster data into predicted groupings in cluster analysis.
where the training data examples are () and (), and the Interval Predictor Model bounds _ and ¯ are parameterised by the parameter vector . The reliability of such an IPM is obtained by noting that for a convex IPM the number of support constraints is less than the dimensionality of the trainable parameters , and hence the scenario approach ...

In numerical analysis, predictor–corrector methods belong to a class of algorithms designed to integrate ordinary differential equations – to find an unknown function that satisfies a given differential equation. All such algorithms proceed in two steps:
