Latent Space Exploration Using Generative Kernel PCA

David Winant, Joachim Schreurs, Johan A. K. Suykens

Kernel PCA is a powerful feature extractor which recently has seen a reformulation in the context of Restricted Kernel Machines (RKMs). These RKMs allow for a representation of ker…

Towards Deterministic Diverse Subset Sampling

Joachim Schreurs, Michaël Fanuel, Johan A. K. Suykens

Determinantal point processes (DPPs) are well known models for diverse subset selection problems, including recommendation tasks, document summarization and image search. In this p…

Leverage Score Sampling for Complete Mode Coverage in Generative Adversarial Networks

Joachim Schreurs, Hannes De Meulemeester, Michaël Fanuel +2

Commonly, machine learning models minimize an empirical expectation. As a result, the trained models typically perform well for the majority of the data but the performance may det…

Determinantal Point Processes Implicitly Regularize Semi-parametric Regression Problems

Michaël Fanuel, Joachim Schreurs, Johan A. K. Suykens

Semi-parametric regression models are used in several applications which require comprehensibility without sacrificing accuracy. Typical examples are spline interpolation in geophy…

Outlier detection in non-elliptical data by kernel MRCD

Joachim Schreurs, Iwein Vranckx, Mia Hubert +2

The minimum regularized covariance determinant method (MRCD) is a robust estimator for multivariate location and scatter, which detects outliers by fitting a robust covariance matr…

The Bures Metric for Generative Adversarial Networks

Hannes De Meulemeester, Joachim Schreurs, Michaël Fanuel +2

Generative Adversarial Networks (GANs) are performant generative methods yielding high-quality samples. However, under certain circumstances, the training of GANs can lead to mode…

Disentangled Representation Learning and Generation with Manifold Optimization

Arun Pandey, Michael Fanuel, Joachim Schreurs +1

Disentanglement is a useful property in representation learning which increases the interpretability of generative models such as Variational autoencoders (VAE), Generative Adversa…

Diversity sampling is an implicit regularization for kernel methods

Michaël Fanuel, Joachim Schreurs, Johan A. K. Suykens

Kernel methods have achieved very good performance on large scale regression and classification problems, by using the Nyström method and preconditioning techniques. The Nyström ap…

Nyström landmark sampling and regularized Christoffel functions

Michaël Fanuel, Joachim Schreurs, Johan A. K. Suykens

Selecting diverse and important items, called landmarks, from a large set is a problem of interest in machine learning. As a specific example, in order to deal with large training…
