A deterministic interpretation of the Kalman filtering formulas is given, using the principle of least squares estimation. The observed signal and the to-be-estimated signal are modeled as being generated as outputs of a finite-dimensional linear system driven by an input disturbance. Postulating ...
Finally, a big factor people forget is any filtering, averaging or discretization that is done. When the sensor changes, it takes time to propagate through the filters based on the filter parameters. And if the discretization is large, you might not even see the change. (If T is at 449,...
Ultra-short-term forecasts in practice mostly utilize statistical methods, including Kalman filtering, auto-regressive models, and neural networks, to establish the internal relationship between historical observations (Lydia et al. [17] ; Tian and Chen [18] ), which is not the focus of this ...
Therefore, fungal communities were constrained to be highly dissimilar in a way that could not be explained by niche-based environmental filtering. In the two deeper soil layers, the confidence interval of the central tendency also overlapped with zero, suggesting an important role of neutral ...
4(d) shows a spectrum after filtering in which only one peak remains. Figure 4(d) shows the detected fluorescent counts on a silicon single-photon detector as a function of normalized pulse laser power, achieving the total flux \({N}_{total}\) = 1,679,000 counts/s. To deduce ...
Subsequently, TF annotations per day were filtered to include only annotations with FDR-corrected Pval < 10−30 in at least one sample. Further filtering the predicted TF to include only TF that are also differentially expressed during reprogramming according to our collected RNA-seq. ATAC-seq ...
Making use of the solution to both the estimation and tracking problems, a constrained estimation problem is solved which shows that the Riccati equation solution has a least squares interpretation that is analogous to the meaning of the covariance matrix in stochastic filtering. This article shows ...

Correlation and covariance techniques are used for time-limited signals. Adaptive filtering, developed for nonstationary signals analysis, is studied. The filter coefficients are reassessed as the signal evolves in time.doi:10.1007/978-3-319-42382-1_20Frédéric Cohen Tenoudji...
