Model-agnostic and diverse explanations for streaming rumour graphs

作者:

Highlights:

• Our approach yields explanations of much higher accumulated utility up to 16x.

• Our approach is robust to concept drift with a 67.95% of explanation accuracy.

• Our approach has indexing performance significantly better in time and space.

• Our embedding-based similarity is much faster to compute than graph measures.

• Our example-based explanations also support the detection accuracy (>=0.95).
