MedianFilter#

class chemotools.smooth.MedianFilter(window_length: int = 3, mode: Literal['reflect', 'constant', 'nearest', 'mirror', 'wrap', 'grid-constant', 'grid-mirror', 'grid-wrap'] = 'nearest', window_size='deprecated')[fuente]

Bases: TransformerMixin, OneToOneFeatureMixin, BaseEstimator

A smoothing transformer that calculates the median filter of the input data.

Parámetros:

  • window_length (int, optional, default=3) – The size of the window to use for the median filter. Must be odd. Default is 3.

  • mode (str, optional, default="nearest") – The mode to use for the median filter. Can be «nearest», «constant», «reflect», «wrap», «mirror» or «interp». Default is «nearest».

  • window_size (int, optional) – Deprecated alias for window_length.

Variables:

n_features_in (int) – The number of features in the training data.

Ejemplos

>>> from chemotools.datasets import load_fermentation_train
>>> from chemotools.smooth import MedianFilter
>>> # Load sample data
>>> X, _ = load_fermentation_train()
>>> # Initialize MedianFilter
>>> md = MedianFilter()
MedianFilter()
>>> # Fit and transform the data
>>> X_smoothed = md.fit_transform(X)
fit(X: ndarray, y=None) → MedianFilter[fuente]

Fit the transformer to the input data.

Parámetros:

  • X (np.ndarray of shape (n_samples, n_features)) – The input data to fit the transformer to.

  • y (None) – Ignored to align with API.

Devuelve:

self – The fitted transformer.

Tipo del valor devuelto:

MedianFilter

transform(X: ndarray, y=None) → ndarray[fuente]

Transform the input data by calculating the median filter.

Parámetros:

  • X (np.ndarray of shape (n_samples, n_features)) – The input data to transform.

  • y (None) – Ignored to align with API.

Devuelve:

X_transformed – The transformed data.

Tipo del valor devuelto:

np.ndarray of shape (n_samples, n_features)
