WebThe RFE method is available via the RFE class in scikit-learn.. RFE is a transform. To use it, first the class is configured with the chosen algorithm specified via the “estimator” argument and the number of features to select via the “n_features_to_select” argument. The algorithm must provide a way to calculate important scores, such as a decision tree. Web9 Feb 2024 · The GridSearchCV class in Scikit-Learn is an amazing tool to help you tune your model’s hyper-parameters. In this tutorial, you learned what hyper-parameters are and what the process of tuning them looks like. You then explored sklearn’s GridSearchCV class and its various parameters.

Web28 Jul 2024 · Custom losses require looking outside sklearn (e.g. at Keras) or writing your own estimator. Model scoring allows you to select between different trained models. Scikit-learn makes custom scoring very easy. The difference is a custom score is called once per model, while a custom loss would be called thousands of times per model. Web1 Jun 2024 · The task is to learn a 1-D gaussian function def gaussian (x, mu, sig): return np.exp (-np.square ( (x-mu)/sig)/2) given some training data. I build the following neural network in Keras: The network is trained simultaneously for both classification and regression. It splits only in the last layer. The input is one-dimensional.
