**TLDR:** A nonlinear dimensionality reduction method that seeks to preserve manifold structure through approximate geodesic distances.

<p>Isomap is built on the assumption that high-dimensional data lies on a lower-dimensional manifold. It estimates geodesic distances through neighborhood relationships and preserves that structure in a lower-dimensional embedding. This can be especially meaningful in problems where nonlinear geometry matters. However, the quality of the neighborhood graph and the level of noise strongly influence performance.</p>
