PCA based Anomaly Detection and Mitigation Approach
In this method, the size of the moving window
was modified from 1 to 33.
the model using a moving window
of 0.5 km outer radius in land cover classes) held the highest AUC value of 0.77 (Fig.
The modified FQRS detector comprises of four stages: (i) amplitude squarer, (ii) moving window
integrator, (iii) moving average filter, and (iv) adaptive threshold.
In order to improve the estimation accuracy of observation noise variance, the moving window
parameter can appropriately be increased properly, and the Helmert variance component estimated by introducing time-correlated forgetting factor is used to achieve the precise weight ratio between GPS and BDS observations; then, the history window data is used to improve the accuracy of observation variance at the current epoch by smoothing the noise; finally, the displacement detection with submillimeter accuracy can be achieved based on the KALMAN filter .
The negative consequence of failing to use moving window
analysis and instead evaluating diversified electrical demand over fixed time periods (e.g., hourly from 5:00 to 6:00 a.m.
where [DELTA][y.sub.MA] stands for the difference between the side values of the processed signal moving window
The new sample in the bottom of the figure is scanned with a moving window
, following normalization to the [-1,1] range.
The lower the [MD.sub.i,j,k] value, the more even the color of the sample in the area covered by the moving window
. Moving the window pixel by pixel, the software can locate the area having the highest MDfc value (HMD.).
[t.sub.n,i]].sup.T] and n is the size of moving window
Based on the score the data obtained was used to calculate Sorenson's similarity coefficient, Shannon's diversity index (11), Range weighted richness (12), Pielou's evenness index (13), Pareto Lorenz curve (14) and Moving window
The how--to sections, for example, show readers how to make and use variability graphs, min-max graphs and moving window
