WebThe prompt is asking you to perform binary classification on the MNIST dataset using logistic regression with L1 and L2 penalty terms. Specifically, you are required to train models on the first 50000 samples of MNIST for the O-detector and determine the optimal value of the regularization parameter C using the F1 score on the validation set. WebThe penalty (aka regularization term) to be used. Defaults to ‘l2’ which is the standard regularizer for linear SVM models. ‘l1’ and ‘elasticnet’ might bring sparsity to the model (feature selection) not achievable with ‘l2’. No penalty is added when set to None. alphafloat, default=0.0001 Constant that multiplies the regularization term.
