New algorithm uncovers hidden anomalies in categorical data for better decision-making.
The article presents a new method for finding unusual data points in categorical data. Instead of looking for outliers in the whole dataset, this method focuses on finding outliers within smaller groups. By using a combination of clustering and statistical analysis, the researchers were able to identify clusters with unusual data points and individual data points that stand out. The results from testing this method on real datasets showed that it is accurate and effective in finding local outliers.
