outlier detectionWe hypothesize that similar objects should have similar outlier scores. To the best of our knowledge, all existing outlier detectors calculate the outlier score for each object independently regardless of the outlier scores of the other objects. Therefore, they do not guarantee that ...
To the best of our knowledge, all existing outlier detectors calculate the outlier score for each object independently regardless of the outlier scores of the other objects. Therefore, they do not guarantee that similar objects have similar outlier scores. To verify our proposed hypothesis, we ...

When the outlier was removed, significance remained (p = 0.004, β = 0.65 (95% CI 0.21, 1.09), R2 = 0.11, Fig. 3B). Figure 2 shows that the highest R2 and lowest p-value occur when the pT is more stringent. Fig. 2 The adjusted R2 and PRS p-values for the ...
Anomaly detection, also referred to as outlier detection, is a data analysis technique used to identify observations or data samples that deviate significantly from the majority of a dataset. These observations are referred to as anomalies or outliers because they differ from expected or typical patte...

Outlier detection method based on standard scoresYaNan Wang
Standard scoreMoving rangeAgricultural monitoring data is the basis of environmental early warning, however, abnormal data is inevitable in the monitoring process. Aiming at the problem that the data of wireless sensor network is abnormal, an outlier detection method is proposed, in order to achieve...
