WitrynaTL;DR. ISOMAP is a non-linear dimension reduction method to reduce the size and complexity of a dataset, projecting it onto a new plain. This method is useful for datasets with non-linear structure, where PCA and MDS will not be appropriate. What is this method? ISOMAP, a Non-Linear Dimension Reduction method.
