RQ4: Why FFT? about defect-prediction HOT 4 CLOSED

First IQ, Median, and 3rd IQ of G-score performance delta of FFT with LR, RF, and SVM:

from defect-prediction.

1/ The scores are ranked based on the delta with Commit.Guru's Logistic Regression.
2/ With the positive median delta, it shows that FFT won most (SVM: 6/9, RF: 6/9, LR: 6/9 cases) up to 18 max absolute difference.

from defect-prediction.

Summary across learners results
1/ different by small effect between fastread + learner versus keyword + learner.
2/ if fastread with the learner > keyword with the learner
Table is sorted based on FFT.

from defect-prediction.

If fastread with the learner (win + tie) in the comparison to keyword with the learner. Sorted for FFT.
