Detection Techniques of Outliers and How to Remove Them voticle.com

In simple terms, outliers are defined as the extreme value that deviates from the other observation on the data. Such observation may indicate having variability in measurement or experimental errors. In other words, it is an observation that diverges itself from the overall pattern seen on a sample.

Outliers can be a serious problem especially when training of machine learning algorithms takes place or while applying statistical techniques.

These (outliers) are often the results of error, this can either be in the measurement or at exceptional system conditions.
