Given a subset S of D, a predictive learner is constructed on S, and given new values of X and Y not in S, predictions will be made for a corresponding Y. These predictions can be computed from any machine lear
We introduce a linear programming-based approach for hyperparameter tuning of machine learning models. The approach finetunes continuous hyperparameters and model parameters through a linear program, enhancing model generalization in the vicinity of an initial model. The proposed method converts hyper...

The following table contains the hyperparameters for the linear learner algorithm. These are parameters that are set by users to facilitate the estimation of model parameters from data. The required hyperparameters that must be set are listed first, in alphabetical order. The optional hyperparameters...

In our case, the MOOP is addressed based on the Pareto Front, which merges multiple metrics in a vector of objective functions that may conflict with each other, characterizing a non-linear problem in the objectives space. Here, an important concept to measure the quality of solutions is the...
