Regularization in Retrieval-Driven Classification of Clustered Microcalcifications for Breast Cancer

Figure 3

Classification performance (AUC) achieved by the case-adaptive classifiers with/without regularization (Ada-Reg-Non, Ada-Reg-Uni and Ada-Reg-Var). The number of retrieved cases 𝑁_𝑟 was varied from 6 to 300. For comparison, results are also shown for the baseline classifier (LR), the classifier trained with all the available cases (LR-all), and the adaptive classifier in [22] (Ada-LR).
