Performance evaluation of DPFCM_GK and other methods under varying privacy budgets using LLCS. (A) The relationship between the test accuracy (%) of various models and privacy budget values. (B) The relationship between the misclassification rate (%) of various models and privacy budget values. (C) The relationship between the misclassification rate (%) of various models and the number of iterations, with the privacy budget fixed at 5. (D-J) When the privacy budget ε is set to 5, the confusion matrices of the DPFCM, DPFCM_GK, LDP-Fed, LDP-FL, LDP-SGD, MGM-DPFL, and MGM-FedSGD models are evaluated using the LLCS dataset.
