“…To demonstrate the effectiveness of the OFHIR algorithm, this section selects five online streaming feature selection algorithms: OFS‐A3M, 25 Fast‐OSFS, 39 OSFS, 39 SAOLA, 40 and OFS‐Density 41 . Meanwhile, two online streaming feature selection algorithms for hierarchical classification learning: KFOHS 27 and HSFSAR 29 are selected. Among them, the significance levels of Fast‐OSFS (abbreviated as FOSFS), OSFS, and SAOLA are all set to 0.01, OFS‐Density (abbreviated to OFSD) sets α$$ \alpha $$ to 0.05, HSFSAR sets λ$$ \lambda $$ = 0.0001 and the parameter δ$$ \delta $$ in KFOHFS is set to 0.0001, respectively.…”

“…It can be seen from Tables 3–6 that the average performance of the OFHIR algorithm all rank first under the four evaluation indicators of Accuracy, H‐F1, LCA‐F1, and TIE. Compared with HSFSAR, 29 OFHIR takes into account the interactivity between features. Therefore, the performance of the algorithm will be improved or flat on most datasets, especially when the number of samples is too large, such as in the Cifar and VOC datasets, the performance under the four evaluation indicators was significantly improved.…”
