Sampled data systems — A sampled data system is a control system where a continuous time plant (control theory) is controlled with a digital device. Under periodic sampling, the sampled data system is time varying but also periodic, and thus it may be modeled by a… … Wikipedia
Model predictive control — Model Predictive Control, or MPC, is an advanced method of process control that has been in use in the process industries such as chemical plants and oil refineries since the 1980s. Model predictive controllers rely on dynamic models of the… … Wikipedia
Data transmission — Data transmission, digital transmission, or digital communications is the physical transfer of data (a digital bit stream) over a point to point or point to multipoint communication channel. Examples of such channels are copper wires, optical… … Wikipedia

Autoregressive moving average model — In statistics, autoregressive moving average (ARMA) models, sometimes called Box Jenkins models after the iterative Box Jenkins methodology usually used to estimate them, are typically applied to time series data.Given a time series of data X t … Wikipedia
Generative model — In statistics, a generative model is a model for randomly generating observed data, typically given some hidden parameters. It specifies a joint probability distribution over observation and label sequences. Generative models are used in machine… … Wikipedia
Audio compression (data) — For processes which reduce the amount of time it takes to listen to and understand a recording, see time compressed speech. Audio compression is a form of data compression designed to reduce the size of audio files. Audio compression algorithms… … Wikipedia
Mixed data sampling — (MIDAS) is an econometric regression or filtering method developed by Ghysels et al. A simple regression example has the regressor appearing at a higher frequency than the regressand: where y is the regressand, x is the regressor, m denotes the… … Wikipedia
