WebManifold learning is an important dimensionality reduction method, which attempts to obtain the intrinsic distribution and geometry structure of high-dimensional data. Multi-dimensional scaling (MDS) [ 36 ] is a classical manifold learning algorithm, which keeps the geometrical structure of original data via holding the distances among points. Web31. jan 2024. · Aim and Scope. Manifold Learning (ML) has been the subject of intensive study over the past two decades in the computer vision and machine learning communities. Originally, manifold learning techniques aim to identify the underlying structure (usually low-dimensional) of data from a set of, typically high-dimensional, observations.
