pyts.preprocessing.MaxAbsScaler

class pyts.preprocessing.MaxAbsScaler[source]

Scale each sample by its maximum absolute value.

Examples

>>> from pyts.preprocessing import MaxAbsScaler
>>> X = [[1, 5, 3, 2, 10, 6, 4, 7],
...      [1, -5, 3, 2, 2, 1, 0, 2]]
>>> scaler = MaxAbsScaler()
>>> scaler.transform(X)
array([[ 0.1,  0.5,  0.3,  0.2,  1. ,  0.6,  0.4,  0.7],
       [ 0.2, -1. ,  0.6,  0.4,  0.4,  0.2,  0. ,  0.4]])

Methods

__init__() Initialize self.
fit([X, y]) Pass.
fit_transform(X[, y]) Fit to data, then transform it.
get_metadata_routing() Get metadata routing of this object.
get_params([deep]) Get parameters for this estimator.
set_output(*[, transform]) Set output container.
set_params(**params) Set the parameters of this estimator.
transform(X) Scale the data.
__init__()[source]

Initialize self. See help(type(self)) for accurate signature.

fit(X=None, y=None)[source]

Pass.

Parameters:
X

Ignored

y

Ignored
Returns:
self : object
fit_transform(X, y=None, **fit_params)

Fit to data, then transform it.

Fits transformer to X and y with optional parameters fit_params and returns a transformed version of X.

Parameters:
X : array-like of shape (n_samples, n_features)

Input samples.

y : array-like of shape (n_samples,) or (n_samples, n_outputs), default=None

Target values (None for unsupervised transformations).

**fit_params : dict

Additional fit parameters.
Returns:
X_new : ndarray array of shape (n_samples, n_features_new)

Transformed array.
get_metadata_routing()

Get metadata routing of this object.

Please check User Guide on how the routing mechanism works.

Returns:
routing : MetadataRequest

A MetadataRequest encapsulating routing information.
get_params(deep=True)

Get parameters for this estimator.

Parameters:
deep : bool, default=True

If True, will return the parameters for this estimator and contained subobjects that are estimators.
Returns:
params : dict

Parameter names mapped to their values.
set_output(*, transform=None)

Set output container.

See Introducing the set_output API for an example on how to use the API.

Parameters:
transform : {“default”, “pandas”, “polars”}, default=None

Configure output of transform and fit_transform.

  • “default”: Default output format of a transformer
  • “pandas”: DataFrame output
  • “polars”: Polars output
  • None: Transform configuration is unchanged

New in version 1.4: “polars” option was added.
Returns:
self : estimator instance

Estimator instance.
set_params(**params)

Set the parameters of this estimator.

The method works on simple estimators as well as on nested objects (such as Pipeline). The latter have parameters of the form <component>__<parameter> so that it’s possible to update each component of a nested object.

Parameters:
**params : dict

Estimator parameters.
Returns:
self : estimator instance

Estimator instance.
transform(X)[source]

Scale the data.

Parameters:
X : array-like, shape = (n_samples, n_timestamps)

Data to scale.
Returns:
X_new : array-like, shape = (n_samples, n_timestamps)

Scaled data.
