Time-Variant and Time-Invariant Lattice Filters for Nonstationary Processes 来自 ResearchGate 喜欢 0 阅读量: 44 作者: T Kailath 摘要: The structure of second-order processes is exposed by specification of whitening filters and modeling filters, or equivalently by Cholesky decompositions of the ...

The attention weights plot is not the same as an autocorrelation plot: The autocorrelation plot refers to a particular sequence, while the attention weights here focus on the impact of each timestep by looking across all covariates and time series. Feature-wise Interpretability Th...
Finally, it is worth emphasizing that sci-FTS is primarily focused on time-invariant and first-order models, as illustrated in Listing 5. However, it was designed to be easily extended to support models characterized for being time-variant and with higher orders. Moreover, it was intrinsically...
We also introduce a variant of DILATE, which provides a smooth generalization of temporally-constrained Dynamic Time Warping (DTW). Enhancing the Locality and Breaking the Memory Bottleneck of Transformer on Time Series Forecasting NeurIPS 2019 - solar, wind we first propose convolutional self-...
The time-variant reliability and its sensitivity of cutting tools under both wear deterioration and an invariant machining condition are analyzed. The wear process is modeled by a Gamma process which is a continuous-state and continuous-time stochastic process with the independent and nonnegative incre...
In addition, the feedback matrix in Tuna (2010) was based on the output matrix and the state transition matrix, while that in this paper is based on the input matrix and a variant of the controllability Gramian. The main contributions of this paper are as follows. For a network of ...
It should be noted that the reason why x and y are the parametric variables here is that the laws of echo delay variation and the initial phase variation are closely related to the parameters and the position (x, y) of the scattering point, that is, the echo has space-variant ...
Based on these five steps, Song and Chissom developed two time series models — the time-invariant model [28] and the time-variant model [29]. Following the work of Song and Chissom, focusing on step (4) and (5), most of researchers focused on various variants of fuzzy time series ...
