Researchers have introduced the Class Angular Distortion Index (CADI), a novel metric for evaluating dimensionality reduction techniques. CADI addresses limitations in existing metrics by assessing the faithfulness of cluster organization in projected data, rather than just separability or assuming spherical clusters. The new index utilizes internal angles among point triples and is differentiable, allowing for optimization in dimensionality reduction methods. AI
