Grid search is a tuning technique that attempts to compute the optimum values of hyperparameters. It is an exhaustive search that is performed on a the specific parameter values of a model. The model is also known as an estimator. See more For the sake of simplicity, we can divide the analytical aspects of a data science project into three parts: 1. The first part would be all about gathering the required data and engineering the features. 2. The second part would … See more A machine learning model has multiple parameters that are not trained by the training set. These parameters control the accuracy of the model. Therefore, the hyperparameters are … See more This article explained how to use the Grid Search to obtain optimal hyperparameters for a machine learning model.
