Researchers have introduced EntroPath, a novel manifold learning method designed to reconstruct geodesic geometry from data graphs. This method utilizes ensembles of diffusion paths, specifically employing a maximum entropy random walk (MERW) to aggregate paths rather than relying on single trajectories or shortest-path distances. EntroPath demonstrates superior performance on synthetic manifolds and single-cell benchmarks, particularly in scenarios with uneven sampling density and distinct branching trajectories, where it more accurately preserves geodesic geometry compared to existing diffusion- and shortest-path-based techniques.
