What is Random State? And Why is it Always 42? - Medium
Web17 Dec 2024 · If you don’t set random_state to 42, every time you run your code again, it will generate a different test set. Over time, you (or your machine learning algorithm) will be able to see the dataset, which you want to avoid. One solution is to save the test set on the first run, and then load it on subsequent runs. Web{random_state} shrinkage : float or dict, default=None Parameter controlling the shrinkage applied to the covariance matrix. when a smoothed bootstrap is generated. The options are: - if `None`, a normal bootstrap will be generated without perturbation. It is equivalent to `shrinkage=0` as well; fame mma 14 stream online
