## dml_ensemble_lm

### Description

As an important integrated learning method, stacking consists of at least two layers of structure, including a primary learner and a secondary learner or a meta-learner used to combine the learner.Stacking first trained the primary learner from the initial data set, and then generated a new data set used to train the secondary learner, in this data set, the output of the primary learner is taken as the sample input characteristics, and the initial sample mark is still taken as the sample mark. Integrate the four basic model through linear model.
