Interpretable Multiple-Kernel Prototype Learning for Discriminative Representation and Feature Selection

no code implementations10 Nov 2019 Babak Hosseini, Barbara Hammer

In this paper, we propose a novel interpretable multiple-kernel prototype learning (IMKPL) to construct highly interpretable prototypes in the feature space, which are also efficient for the discriminative representation of the data.

Interpretable Discriminative Dimensionality Reduction and Feature Selection on the Manifold

no code implementations19 Sep 2019 Babak Hosseini, Barbara Hammer

In this research, we propose the interpretable kernel DR algorithm (I-KDR) as a new algorithm which maps the data from the feature space to a lower dimensional space where the classes are more condensed with less overlapping.

Confident Kernel Sparse Coding and Dictionary Learning

no code implementations12 Mar 2019 Babak Hosseini, Barbara Hammer

In this work, we propose a novel confident K-SRC and dictionary learning algorithm (CKSC) which focuses on the discriminative reconstruction of the data based on its representation in the kernel space.

Multiple-Kernel Dictionary Learning for Reconstruction and Clustering of Unseen Multivariate Time-series

no code implementations5 Mar 2019 Babak Hosseini, Barbara Hammer

Furthermore, we obtain sparse encodings for unseen classes based on the learned MKD attributes, and upon which we propose a simple but effective incremental clustering algorithm to categorize the unseen MTS classes in an unsupervised way.

Feasibility Based Large Margin Nearest Neighbor Metric Learning

no code implementations18 Oct 2016 Babak Hosseini, Barbara Hammer

In this paper, we address the feasibility of LMNN's optimization constraints regarding these target points, and introduce a mathematical measure to evaluate the size of the feasible region of the optimization problem.

Efficient Metric Learning for the Analysis of Motion Data

1 code implementation17 Oct 2016 Babak Hosseini, Barbara Hammer

We investigate metric learning in the context of dynamic time warping (DTW), the by far most popular dissimilarity measure used for the comparison and analysis of motion capture data.
