Abstract:

We propose a new heterogeneous transfer learning method, which uses related heterogeneous feature dataset. We use translation invariant kernels(Euclidean kernels and RBF kernels) to map the target dataset and the related dataset to a new reproducing kernel Hilbert space, in which the two datasets have equal feature dimensions and similar distributions and reserve their topological property. The experimental results show that our method works well and the method based on the Euclidean kernel improves accuracy by more than 5%~10%.

Key words: heterogeneous transfer learning, translation invariant kernel, RKHS
