DeepEstimator(module, loss_fn='mse', optimizer_fn='sgd', lr=0.001, is_feature_incremental=False, device='cpu', seed=42, **kwargs)

Bases: Estimator

Abstract base class that implements basic functionality of River-compatible PyTorch wrappers.

PARAMETER	DESCRIPTION
module	Torch Module that builds the autoencoder to be wrapped. The Module should accept parameter n_features so that the returned model's input shape can be determined based on the number of features in the initial training example. TYPE: Type[Module]
loss_fn	Loss function to be used for training the wrapped model. Can be a loss function provided by torch.nn.functional or one of the following: 'mse', 'l1', 'cross_entropy', 'binary_crossentropy', 'smooth_l1', 'kl_div'. TYPE: Union[str, Callable] DEFAULT: 'mse'
optimizer_fn	Optimizer to be used for training the wrapped model. Can be an optimizer class provided by torch.optim or one of the following: "adam", "adam_w", "sgd", "rmsprop", "lbfgs". TYPE: Union[str, Callable] DEFAULT: 'sgd'
lr	Learning rate of the optimizer. TYPE: float DEFAULT: 0.001
device	Device to run the wrapped model on. Can be "cpu" or "cuda". TYPE: str DEFAULT: 'cpu'
seed	Random seed to be used for training the wrapped model. TYPE: int DEFAULT: 42
**kwargs	Parameters to be passed to the Module or the optimizer. DEFAULT: {}

clone(new_params=None, include_attributes=False)

Clones the estimator.

PARAMETER	DESCRIPTION
new_params	New parameters to be passed to the cloned estimator. TYPE: dict[Any, Any] | None DEFAULT: None
include_attributes	If True, the attributes of the estimator will be copied to the cloned estimator. This is useful when the estimator is a transformer and the attributes are the learned parameters. DEFAULT: False

RETURNS	DESCRIPTION
DeepEstimator	The cloned estimator.

draw()

Draws the wrapped model.

initialize_module(x, **kwargs)

PARAMETER	DESCRIPTION
module	The instance or class or callable to be initialized, e.g. self.module.
kwargs	The keyword arguments to initialize the instance or class. Can be an empty dict. TYPE: dict DEFAULT: {}

RETURNS	DESCRIPTION
instance	The initialized component.

RollingDeepEstimator(module, loss_fn='mse', optimizer_fn='sgd', lr=0.001, device='cpu', seed=42, window_size=10, append_predict=False, **kwargs)

Bases: DeepEstimator

Abstract base class that implements basic functionality of River-compatible PyTorch wrappers including a rolling window to allow the model to make predictions based on multiple previous examples.

PARAMETER	DESCRIPTION
module	Torch Module that builds the autoencoder to be wrapped. The Module should accept parameter n_features so that the returned model's input shape can be determined based on the number of features in the initial training example. TYPE: Type[Module]
loss_fn	Loss function to be used for training the wrapped model. Can be a loss function provided by torch.nn.functional or one of the following: 'mse', 'l1', 'cross_entropy', 'binary_crossentropy', 'smooth_l1', 'kl_div'. TYPE: Union[str, Callable] DEFAULT: 'mse'
optimizer_fn	Optimizer to be used for training the wrapped model. Can be an optimizer class provided by torch.optim or one of the following: "adam", "adam_w", "sgd", "rmsprop", "lbfgs". TYPE: Union[str, Callable] DEFAULT: 'sgd'
lr	Learning rate of the optimizer. TYPE: float DEFAULT: 0.001
device	Device to run the wrapped model on. Can be "cpu" or "cuda". TYPE: str DEFAULT: 'cpu'
seed	Random seed to be used for training the wrapped model. TYPE: int DEFAULT: 42
window_size	Size of the rolling window used for storing previous examples. TYPE: int DEFAULT: 10
append_predict	Whether to append inputs passed for prediction to the rolling window. TYPE: bool DEFAULT: False
**kwargs	Parameters to be passed to the Module or the optimizer. DEFAULT: {}
