NBEATSHyperparams

nbeats_model.NBEATSHyperparams · inherits PydanticBaseModel

Tunable training knobs; aligned with TFT / shorter training.

Attributes

Parameter	Type	Default	Description
input_size	int	128	NeuralForecast input_size (lookback).
max_steps	int	25	Lightning optimization steps per fit (not forecast horizon; tasks cap h at 128).
batch_size	int	64	Minibatch size (series per step); larger improves GPU/CPU throughput until memory-bound.

train(self, y_context: np.ndarray, y_target: np.ndarray, timestamps_context: np.ndarray, timestamps_target: np.ndarray, x_context: Optional[np.ndarray] = None, x_target: Optional[np.ndarray] = None, **kwargs) -> NBEATSModel

Parameter	Type	Default	Description
y_context	np.ndarray	-	(undocumented)
y_target	np.ndarray	-	(undocumented)

timestamps_target	np.ndarray	-	(undocumented)
x_context	Optional[np.ndarray]	None	(undocumented)
x_target	Optional[np.ndarray]	None	(undocumented)
**kwargs		-	(undocumented)

Returns: NBEATSModel (the fitted forecaster).

predict(self, y_context: np.ndarray, timestamps_context: np.ndarray, timestamps_target: np.ndarray, x_context: Optional[np.ndarray] = None, x_target: Optional[np.ndarray] = None, **kwargs) -> np.ndarray
