WitrynaIf feature_names_in_ is not defined, then the following input feature names are generated: ["x0", "x1", ..., "x (n_features_in_ - 1)"]. If input_features is an array-like, then input_features must match feature_names_in_ if feature_names_in_ is defined. Returns: feature_names_outndarray of str objects Transformed feature names. Witryna1 lip 2024 · Now, we have the input data ready. Let’s see how to write a custom model in PyTorch for logistic regression. The first step would be to define a class with the model name. This class should derive torch.nn.Module. Inside the class, we have the __init__ function and forward function.
