https://doi.org/10.1007/978-3-642-71247-0 solves this issue by projecting high-dimensional data into a low-dimensional space where meaningful distances allow unbiased function estimation. However, projection pursuit only considers projections onto lines and the unbiased function depends on the sample size. We introduce deep projection purs

Dorothea Ritter-Röhr (Psychoanalyse)tended to improve clustering of the resulting output space. Improvement is achieved by abandoning the SOM’s rigid lattice structure in favor of a more expressive output topology afforded by Uniform Manifold Approximation and Projection (UMAP), which is incrementally learned in conjunction with SOUMA

https://doi.org/10.1007/978-3-322-83403-4we consider linear data mappings included in vector quantization models, such as .-means++, neural gas, or self-organizing maps, to achieve representations in a lower-dimensional data space. To this end, we show how additional data knowledge can be integrated into the models. The additional data str

The prototype based formulations make such models intuitive and naturally amenable to interpretation. I will present a series of generalizations and extensions

In our analysis, . theory from kernel density estimation relates the number of VQ prototypes to observed sample size, dimension, and complexity, all of which
