SQuadMDS: A lean Stochastic Quartet MDS improving global structure preservation in neighbor embedding like t-SNE and UMAP

, with data points. The method can be combined with force directed layouts of the family of neighbour embedding such as -SNE, to produce embeddings that preserve both the global and the local structures of the data.Experiments assess the quality of the embeddings produced by the standalone version and its hybrid extension both quantitatively and qualitatively, showing competitive results outperforming state-of-the-art approaches. Codes are available at .
