Learning primal-dual sparse kernel machines

1 code implementation27 Aug 2021 Riikka Huusari, Sahely Bhadra, Cécile Capponi, Hachem Kadri, Juho Rousu

In this paper, instead of using the traditional representer theorem, we propose to search for a solution in RKHS that has a pre-image decomposition in the original data space, where the elements don't necessarily correspond to the elements in the training set.

Cross-view kernel transfer

no code implementations14 Oct 2019 Riikka Huusari, Cécile Capponi, Paul Villoutreix, Hachem Kadri

We consider the kernel completion problem with the presence of multiple views in the data.

Multi-view Metric Learning in Vector-valued Kernel Spaces

no code implementations21 Mar 2018 Riikka Huusari, Hachem Kadri, Cécile Capponi

We consider the problem of metric learning for multi-view data and present a novel method for learning within-view as well as between-view metrics in vector-valued kernel spaces, as a way to capture multi-modal structure of the data.

Metric Learning

On multi-class learning through the minimization of the confusion matrix norm

no code implementations16 Mar 2013 Sokol Koço, Cécile Capponi

Indeed, recent results show that using the norm of the confusion matrix as an error measure can be quite interesting due to the fine-grain informations contained in the matrix, especially in the case of imbalanced classes.
