Web13 jun. 2024 · GridSearchCV is a technique for finding the optimal parameter values from a given set of parameters in a grid. It’s essentially a cross-validation technique. The model as well as the parameters must be entered. After extracting the best parameter values, predictions are made. How do you define GridSearchCV? http://scikit-neuralnetwork.readthedocs.io/en/latest/guide_sklearn.html
