| Abstract: | TIn our report,several outliers detection algorithm were introduced and their characteristics were summarized.Based on the shortages of algorithm and the actuality of the warning system,a distance sum-based outliers detection algorithms was used to analyze the gas concentration,and the abnormity data were found.The test results indicated that the model can eliminate the error alarm phenomenon effectively. |
