数学中，outlier表示离群点，离群点（outlier）是指数值中，远离数值的一般水平的极端大值和极端小值。因此，也称之为歧异值，有时也称其为野值。形成离群点的主要原因有：首先可能是采样中的误差，如记录的偏误，工作人员出现笔误，计算错误等，都有可能产生极端大值或者极端小值。其次可能是被研究现...

While this might look basic, the fact that an expert in Chinese characters wrote it manually matters a lot. It’s not a one-line basic definition, it’s an actual explanation with cited references (although not shown in the image). I also love the fact that the simplification process ...
aTo overcome the problem of outlier data in the regression analysis for numerical-based damage spectra, the C4.5 decision tree learning algorithm is used to predict damage in reinforced concrete buildings in future earthquake scenarios. Reinforced concrete buildings are modelled as single-degree-of-free...
aFor years it was held in various halls in London, outgrowing each of them in turn until, in answer to enthusiastic invitations to bring it to different parts of the country, the decision was taken to move outside the capital 多年来它在伦敦,比长得快反过来举行了以各种各样的大厅每一他们直...
Before applying the data mining techniques like association, classification or clustering noisy and outliers should be removed. In this paper we are trying to find similarities and differences between noisy data and outliers .Actually most of the data mining users are thing that these two are same...
This study aimed to determine the outlier values in live-weight performance data of Japanese quails. Japanese quails were grown under the same conditions, and, after being divided according to gender, the live weight data of quails up to 56 days of age (7 weeks) was collected. For both mal...
