No fuss metric learning, a Hilbert space scenario

Faraki, Masoud; Harandi, Mehrtash; Porikli, Fatih

Description

In this paper, we devise a kernel version of the recently introduced keep it simple and straightforward metric learning method, hence adding a novel dimension to its applicability in scenarios where input data is non-linearly distributed. To this end, we make use of the infinite dimensional covariance matrices and show how a matrix in a reproducing kernel Hilbert space can be projected onto the positive cone efficiently. In particular, we propose two techniques towards projecting on the...[Show more]
