An efficient radius-incorporated MKL algorithm for Alzheimer׳s disease prediction

作者:

Highlights:

• The objective of our L2BRMKL is convex and can be globally optimized.

• Our L2BRMKL achieves better classification accuracy by automatically tuning C.

• The objective of L2BRMKL is provably to be an upper bound of generalization error.

• Our L2BRMKL tends to select kernels with more discriminative power.

• Our L2BRMKL is more computationally efficient than other radius-incorporated ones.
