      Why It's Trending Now

      Outlier detection is a process that involves identifying data points that deviate significantly from the norm. This can be done using various statistical methods, such as the Z-score, Mahalanobis distance, and One-Class SVM. These techniques help to identify outliers by measuring the distance between each data point and the center of the data distribution. When a data point exceeds a certain threshold, it is flagged as an outlier.

    Outlier detection is relevant for anyone working with data, including:
