Witrynasklearn.linear_model. .LogisticRegression. ¶. Logistic Regression (aka logit, MaxEnt) classifier. In the multiclass case, the training algorithm uses the one-vs-rest (OvR) scheme if the ‘multi_class’ option is set to ‘ovr’, and uses the cross-entropy loss if the ‘multi_class’ option is set to ‘multinomial’. Witrynatorch.nn These are the basic building blocks for graphs: torch.nn Containers Convolution Layers Pooling layers Padding Layers Non-linear Activations (weighted sum, nonlinearity) Non-linear Activations (other) Normalization Layers Recurrent Layers Transformer Layers Linear Layers Dropout Layers Sparse Layers Distance Functions …
