Numerical simulations … WebJul 1, 2024 · Abstract. We present a connection between two dynamical systems arising in entirely different contexts: the Iteratively Reweighted Least Squares (IRLS) algorithm used in compressed sensing and sparse recovery to find a minimum ℓ 1-norm solution in an affine space, and the dynamics of a slime mold (Physarum polycephalum) that finds the …

WebAlgorithm pIRLS is an Iteratively Reweighted Least Squares (IRLS) Algorithm that provably converges for all p at least 2. The algorithm converges geometrically and can thus be used to solve problems to a high accuracy. You may refer to the paper for the analysis and proof of convergence guarantees. Using the Code WebThe method relies on the Newton-Raphson algorithm, but is equivalent to Fisher scoring when using the canonical link (e.g., logit for logistic regression, and log for Poisson). 2 However, at each iteration of the Newton-Raphson algorithm, IRLS computes the closed-form solution to a weighted least squares problem. Interestingly, then, it takes ...
