New framework estimates manifold dimensions by analyzing local graph structure

Researchers have developed a new framework for estimating manifold dimensions by analyzing local graph structures and regression on local PCA coordinates. This approach explicitly accounts for the manifold's curvature, offering an alternative to methods that assume local flatness. The proposed framework includes two estimators, quadratic embedding (QE) and total least squares (TLS), which have shown competitive and often superior performance compared to existing state-of-the-art methods on both synthetic and real-world datasets.
