Fig 3. Feature rank instability (FRI) analysis as a function of number of projects aggregated.

Fig 3

As the number of projects increased, FRI decreased (i.e. pFI ranking became more stable). (A, B) Expected FRI calculated for all 46 features. BPlog had an average FRI of 174.40 ± 2.14 with 2-project aggregation and 13.03 ± 0.34 with 25-project aggregation (A). Similarly, BPXGB started with an average FRI of 153.83 ± 3.06 that decreased to 11.65 ± 0.33 at 25 projects (B). (C, D) Focusing only on the bottom five features by pFI to calculate FRI, BPlog had an average FRI of 20.41 ± 0.75 with 2-project aggregation and decreased to 0.96 ± 0.08 with 25-project aggregation (C). Similarly, BPXGB started with an average FRI of 7.77 ± 0.37 and decreased to 0.56 ± 0.06 for the bottom five features with 25-project aggregation (D).
