Journal ArticleDOI
Visualizing the quality of dimensionality reduction
TL;DR: This work analyzes the characteristics of the co-ranking framework, focusing on interpretability and controllability in evaluation scenarios where a fine-grained assessment of a given visualization is desired and proposes how to link the evaluation to point-wise quality measures.
Journal ArticleDOI
Metric learning for sequences in relational LVQ
TL;DR: This work proposes a metric learning scheme which allows for an autonomous learning of parameters (such as the underlying scoring matrix in sequence alignments) according to a given discriminative task in relational LVQ, and offers an increased interpretability of the results by pointing out structural invariances for the given task.
Proceedings ArticleDOI
Linear basis-function t-SNE for fast nonlinear dimensionality reduction
TL;DR: This work proposes an extension of t-SNE to an explicit mapping and finds that its generalization ability is good when evaluated with the standard quality curve, and opens the way towards efficient nonlinear dimensionality reduction techniques as required in interactive settings.
Journal ArticleDOI
Relational generative topographic mapping
TL;DR: In this article, a method which extends the generative topographic mapping (GTM) to relational data and which allows to achieve a sparse representation of data characterized by pairwise dissimilarities, in latent space is proposed.
Proceedings Article
Out-of-sample kernel extensions for nonparametric dimensionality reduction
TL;DR: ESANN 2012 : 20th European Symposium on Artificial Neural Networks, Computational Intelligence and Machine Learning.
