Results for the domain adaptation with ADNI (source) and AIBL (target) data. In addition to the proposed domain adaptation with instance weighting, we evaluate four strategies that use either one of the datasets (I and II), merge both (III), and combine both with c = 0.5. Discs show mean classification accuracy over 50 samples and bars indicate standard error. We vary the size of the training dataset from AIBL (x-axis), where the remaining AIBL data is used for testing.
