When One Point Is Not Enough: Addressing Ambiguous Instances in Dimensionality Reduction by Splitting
arXiv:2605.23540v1 Announce Type: new Abstract: Dimensionality Reduction (DR) methods are widely used to visualize high-dimensional data. One key task in DR-based analysis is discovering neighborhoods, which relies on analyzing the fine-grained local structure of a projection. However, DR is an inherently lossy process; no technique can perfectly preserve the high-dimensional relationships, and projections therefore contain visual artifacts. In this paper, we highlight a typically overlooked source of visual artifacts: ambiguous instances. These are instances that are highly similar to multipl
The proliferation of high-dimensional data across various fields necessitates more accurate and reliable dimensionality reduction techniques to extract meaningful insights.
Improving dimensionality reduction accuracy directly enhances the interpretability and utility of high-dimensional data visualization, crucial for decision-making in AI and data science.
This research introduces a novel approach to address fundamental ambiguities in dimensionality reduction, potentially leading to more truthful and less artifact-prone data representations.
