Table 4.
Mean testing performance (in [%]) of 50 repetitions of the semisupervised FL model. Exploring the impact of the number of tree models in the SecureBoost component on the performance of semisupervised FL. Fixed parameters: proportion 0.3 in the first PU (PU1), proportion 0.5 in the second PU (PU2). The depth of the tree in SecureBoost is 3.
