Line search convergence tolerance
NettetIn the line search descent methods, the optimization technique picks a direction δj to begin with, for the jth step and carries out a search along this direction from the previous experimental point, to generate a new iterate. The iterative process looks like: … Nettet1. feb. 2001 · In order to improve convergence, Crisfield 1991 proposed a line search technique for the global iterations and Armero and Jeremić 2001 even used a line search technique for the local iterations.

Default Rα l =10−8 R l α = 10 - 8. Cf C f, field conversion ratio used in scaling the relationship between two active fields when one is of negligible magnitude. NettetLine searches help to prevent divergence of equilibrium iterations resulting from the inexact Jacobian produced by the quasi-Newton method. The line search method is …

Benchmarks on different machine learning problems illustrate large performance gains of the proposed variants. 1 Introduction The Frank-Wolfe (FW) or conditional gradient algo- raymond s. mutchlerNettetWhere the convergence tolerance of iterations was set to 0 ( setTol (0.0)) The Spark documentation state: "Smaller value will lead to higher accuracy with the cost of more iterations. Default is 1E-6.
