Revised Conditional t-SNE: Looking Beyond the Nearest Neighbors

1 code implementation7 Feb 2023 Edith Heiter, Bo Kang, Ruth Seurinck, Jefrey Lijffijt

Conditional t-SNE (ct-SNE) is a recent extension to t-SNE that allows removal of known cluster information from the embedding, to obtain a visualization revealing structure beyond label information.

Topologically Regularized Data Embeddings

1 code implementation9 Jan 2023 Edith Heiter, Robin Vandaele, Tijl De Bie, Yvan Saeys, Jefrey Lijffijt

In some cases, users may have prior topological knowledge about the data, such as a known cluster structure or the fact that the data is known to lie along a tree- or graph-structured topology.

ExClus: Explainable Clustering on Low-dimensional Data Representations

no code implementations4 Nov 2021 Xander Vankwikelberge, Bo Kang, Edith Heiter, Jefrey Lijffijt

Dimensionality reduction and clustering techniques are frequently used to analyze complex data sets, but their results are often not easy to interpret.

Clustering Dimensionality Reduction

Factoring out prior knowledge from low-dimensional embeddings

no code implementations2 Mar 2021 Edith Heiter, Jonas Fischer, Jilles Vreeken

Low-dimensional embedding techniques such as tSNE and UMAP allow visualizing high-dimensional data and therewith facilitate the discovery of interesting structure.
