It is shown that this approach may give unsatisfactory results when applied to imaging systems whose noise characteristics vary substantially over time. Such ...
In this study we show how a signal plus noise formulation can be used to improve the performance of auto-regressive shape classifiers in environments with ...
causal noise-shaping filter with infinite order (i.e.. 1. ][ ][ i i r itwh tx. , where hi is coefficient of a filter). In practice, using the infinite number ...
Bibliographic details on Auto-regressive shape classifiers in time varying noise.
Here, we describe two methods based on autoregressive (AR) models: the short-time autoregressive method (ST-AR) and the Kalman smoother (KS). These two methods ...

Jun 12, 2020 · No process noise is added before the 60th time unit so that the trajectories are entirely driven by the AR and CR parameters. The vertical ...
The autoregressive model specifies that the output variable depends linearly on its own previous values and on a stochastic term (an imperfectly predictable ...

Apr 4, 2023 · Abstract. This paper considers statistical inference of time-varying network vector autoregression models for large-scale time series.
A series of simulations show that the proposed classification scheme can achieve high classification rates under realistic conditions, such as low signal-to- ...
