explanation by feature importance

main idea

to explain that anomaly to the user, we can just say that attribute f1 contributed to the abnormality of the square data point.

Non-weighted feature importance

1999.VLDB.Finding intensional knowledge of distance-based outliers

  • define the outlier categories C = {"trivial outlier," "weak outlier," "strongest outlier"} to help gain better insights about the nature of outliers.

explanation by feature values

main idea

explanation by data points comparison

main idea

what is the difference between anomalies and regular data points.

explanation by structure analysis

main idea

x1 and x2 are anomalies for the cluster of round instances and why it is the case, that y is an anomaly for the the triangles and why, and finally that z is an anomaly

for the squares and why.
