Proposing the Curvature-Augmented Manifold Embedding and Learning (CAMEL) method as a novel approach to dimensional reduction and data visualization.
Tiivistelmä
The content introduces the CAMEL method, focusing on formulating the DR problem as a mechanistic/physics model. It reviews existing DR methods, discusses a new force field model inspired by physics, and applies CAMEL to various learning tasks. The comparison with existing models like tSNE, UMAP, TRIMAP, and PacMap is performed using visual comparisons and metrics-based evaluations. The study concludes with suggestions for future work.
