    GridSearchCV implements a "fit" and a "score" method. It also implements "score_samples", "predict", "predict_proba", "decision_function", "transform" and "inverse_transform" if they are implemented in the estimator used. The parameters of the estimator used to apply these methods are optimized by cross-validated grid-search over a parameter grid.

The KNN Classification algorithm itself is quite simple and intuitive. When a data point is provided to the algorithm, with a given value of K, it searches for the K nearest neighbors to that data point. The nearest neighbors are found by calculating the distance between the given data point and the data points in the initial dataset.

Limitations. The results of GridSearchCV can be somewhat misleading the first time around. The best combination of parameters found is more of a conditional "best" combination. This is due to the fact that the search can only test the parameters that you fed into param_grid.There could be a combination of parameters that further improves the.

I'm looking to tune the parameters for sklearn's MLP classifier but don't know which to tune/how many options to give them? Example is learning rate. should i give it [.0001,.001,.01,.1,.2,.3]? or is that too many, too little etc.. i have no basis to know what is a good range for any of the parameters. Processing power is limited so i can't. GridSearchCV implements a "fit" and a "score" method. It also implements "score_samples", "predict", "predict_proba", "decision_function", "transform" and "inverse_transform" if they are implemented in the estimator used. The parameters of the estimator used to apply these methods are optimized by cross-validated grid-search over a parameter grid.
