RPT: Robustness-Performance Trade-Off

Description Usage Arguments Value References Examples

View source: R/stability.R

Description

A variation on the F-measure (precision and recall) to assess robustness versus classification performance.

Usage

1
RPT(stability, performance, beta = 1)

Arguments

stability

Stability metric i.e. result from jaccard, sorensen, etc.

performance

Model performance e.g. accuracy

beta

Relative of importance of stability versus performance. Default beta = 1 treats stability and performance equally.

Value

Harmonic mean of robustness and classification performance
