Elastic principal graph algorithm
WebThis makes the algorithm very effective, especially for parallel implementations. Another advantage is that the same algorithmic kernel is applied to construct principal manifolds … WebMay 18, 2005 · Principal manifolds serve as useful tool for many practical applications. These manifolds are defined as lines or surfaces passing through “the middle” of data distribution. We propose an algorithm for fast construction of grid approximations of principal manifolds with given topology. It is based on analogy of principal manifold and …

Obviously, the lasso is a special case of the elastic net with λ2 = 0. Given a fixed λ2, the LARS-EN algorithm (Zou & Hastie 2003) efficiently solves the elastic net problem for all λ1 with the computation cost as a single least squares fit.
