Smolyak Method for Solving Dynamic Economic Models: Lagrange Interpolation, Anisotropic Grid and Adaptive Domain (with Kenneth L. Judd, Lilia Maliar and Serguei Maliar). Journal of Economic Dynamics & Control 44 (2014) 92–123. First, we propose a more effcient implementation of the Smolyak method for interpolation, namely, we show how to avoid costly evaluations of repeated basis functions in the conventional Smolyak formula. Second, we extend the Smolyak method to include anisotropic constructions; this allows us to target higher quality of approximation in some dimensions than in others. Third, we show how to effectively adapt the Smolyak hypercube to a solution domain of a given economic model. Finally, we advocate the use of low-cost fixed-point iteration, instead of conventional time iteration. In the context of one- and multi-agent growth models, we find that the proposed techniques lead to substantial increases in accuracy and speed of a Smolyak-based projection method for solving dynamic economic models.

aggreating_predictions_sklearn

# Objectives * Create a training function that train the model many time and store the results. * Create a function that collect previous trained model and provide predictions. * I want to do it in parallel using joblib [this library is used to parallelize in Sklearn]
