1 # LLE (Locally Linear Embedding) 2 3 ML D5 4 5 **Definition:** LLE is a dimensionality reduction technique that uses manifold learning instead of projection. 6 7 LLE works by finding the distance between an instance and its nearest neighbors and then lookking for a low-dimensional representation of the training set where these relationships are best preserved. 8 9 This approach is good at unrolling twisted manifolds when there is not too much noise.
