Appropriateness of performance indices for imbalanced data classification: An analysis
作者:
Highlights:
• Applicability of popular indices on imbalanced classification problem is analyzed.
• Two fundamental constraints are proposed to evaluate the appropriateness of an index.
• Remedial modifications are suggested in case of violation of constraint.
• A third proposed condition validates the quality of information returned by an index.
• Theoretical findings are empirically validated through extensive experiments.
