    en.wikipedia.org/wiki/Estimator

    A consistent estimator is an estimator whose sequence of estimates converge in probability to the quantity being estimated as the index (usually the sample size) grows without bound. In other words, increasing the sample size increases the probability of the estimator being close to the population parameter.

    The goal is to estimate the parameters of the filter , and at each time we refer to the current estimate as and the adapted least-squares estimate by +. w n {\displaystyle \mathbf {w} _{n}} is also a column vector, as shown below, and the transpose , w n T {\displaystyle \mathbf {w} _{n}^{\mathit {T}}} , is a row vector .

  4. Real-time data - Wikipedia

    en.wikipedia.org/wiki/Real-time_data

    Real-time data (RTD) is information that is delivered immediately after collection. There is no delay in the timeliness of the information provided. Real-time data is often used for navigation or tracking. [1] Such data is usually processed using real-time computing although it can also be stored for later or off-line data analysis.

  5. Kalman filter - Wikipedia

    en.wikipedia.org/wiki/Kalman_filter

    The predict phase uses the state estimate from the previous timestep to produce an estimate of the state at the current timestep. This predicted state estimate is also known as the a priori state estimate because, although it is an estimate of the state at the current timestep, it does not include observation information from the current timestep.

  7. State observer - Wikipedia

    en.wikipedia.org/wiki/State_observer

    In control theory, a state observer, state estimator, or Luenberger observer is a system that provides an estimate of the internal state of a given real system, from measurements of the input and output of the real system. It is typically computer-implemented, and provides the basis of many practical applications.
