Witryna6 lip 2014 · This paper presents LLE based on orthogonal matching pursuit (OMP) and applies it to classification tasks and experimental results show that the proposed method is promising. Locally Linear Embedding (LLE) is a sort of powerful nonlinear dimensionality reduction algorithms. The basic idea behind the LLE method is that … Witrynadata points into the embedding space, where the classification of these points is done by a classifier, such as K Nearest Neighbor (KNN) [1]. Our experimental results on various benchmark data sets show that this algorithm is effective for classification problems in contrast to SLLE, and SDE. There is an interesting observation: SSDE could
