Rare category exploration via wavelet analysis: Theory and applications

作者：

Highlights：

• We propose a novel approach RCEWA for RCE which achieves a linear time complexity.

• We provide theoretical proofs for the effectiveness of using wavelet analysis for RCE.

• Experiments show that RCEWA outperforms the existing algorithms w.r.t. F-score.
