Mean testing performance (in [%]) of 50 repetitions of the semisupervised FL model. Exploring the impact of the number of SecureBoost and PU components on model performance. Fixed parameters: The proportion for PU₁ is 0.3, and for PU₂, it is 0.5. The number of trees in SecureBoost_{{1, 2, 3}} is 10, 20, and 30 respectively, and the depth of the trees is 3.

Number of PU	Number of SecureBoost	Acc	UAR	UF1
1 (PU{1})	2 (SecureBoost{1, 2})	80.225	80.240	80.216
2 (PU{1, 2})	3 (SecureBoost{1, 2, 3})	80.601	80.630	80.594
3 (PU{1, 2, 3})	4 (SecureBoost{1, 2, 3, 4})	80.601	80.622	80.590
