Fig. 4. Generalizability evaluation.

Generalizability comparison of Joint MAPLE trained by slice 15 and FTL-Joint MAPLE trained by the random slice selection manner. The acceleration rate is R = 12 (4×3) and a complementary uniform sampling is used. For slice 15, two methods perform closely. For slices 30 and 42 which are unseen for Joint MAPLE, the mapping performance of the proposed FTL-Joint MAPLE is better than Joint MAPLE in all parameters which is an indicator of better obtained generalizability with whole-brain training.
