WebThank you for your answers. @mschmitz About the Detect Outlier algorithm I was just wondering that when I set the "number of outliers" to 10 it would give me the first 10 examples as outlier = true - and when I set the "number of outliers" to 15 it would give me the first 15 examples as outliers. Anyway the LOF algorithm was a good hint, however i … WebOne is as you suggest: classify the documents and define as an outlier anything that is distant from the nearest class (e.g. using standard deviations). Or if you use a probabilistic classifier, such as naive Bayes, you could then define outliers as documents with a very low maximum likelihood. WebIntuitively, a document is a Type O outlier when it does not appear to be similar to documents of any single class. In contrast, a document is a Type M outlier when it … fasttrack microsoft login
