Webb11 apr. 2024 · X contains 5 features, and y contains one target. ( How to create datasets using make_regression () in sklearn?) X, y = make_regression (n_samples=200, n_features=5, n_targets=1, shuffle=True, random_state=1) The argument shuffle=True indicates that we are shuffling the features and the samples. Webb12 jan. 2024 · UPDATE: How to set global randomseed for sklearn models: Given that sklearn does not have its own global random seed but uses the numpy random seed we can set it globally with the above : np.random.seed (seed) Here is a little experiment for scipy library, analogous would be sklearn (generating random numbers-usually weights):

Webb11 apr. 2024 · Let’s say the target variable of a multiclass classification problem can take three different values A, B, and C. An OVR classifier, in that case, will break the multiclass classification problem into the following three binary classification problems.
