etna.analysis.RelevanceTable

class RelevanceTable(greater_is_better: bool)

Bases: ABC, BaseMixin

Abstract class for relevance table computation.

Init RelevanceTable.

Parameters:

greater_is_better (bool) – bool flag, if True the biggest value in relevance table corresponds to the most important exog feature

abstract __call__(df: DataFrame, df_exog: DataFrame, return_ranks: bool = False, **kwargs) → DataFrame

Compute relevance table.

For each series in df compute relevance of corresponding series in df_exog.

Parameters:

• df (DataFrame) – dataframe with series that will be used as target

• df_exog (DataFrame) – dataframe with series to compute relevance for df

• return_ranks (bool) – if False return relevance values else return ranks of relevance values

Returns:

dataframe of shape n_segment x n_exog_series, relevance_table[i][j] contains relevance of j-th df_exog series to i-th df series

Return type:

relevance table

set_params(**params: dict) → Self

Return new object instance with modified parameters.

Method also allows to change parameters of nested objects within the current object. For example, it is possible to change parameters of a model in a Pipeline.

Nested parameters are expected to be in a <component_1>.<...>.<parameter> form, where components are separated by a dot.

Parameters:

**params (dict) – Estimator parameters

Returns:

New instance with changed parameters

Return type:

Self

Examples

>>> from etna.pipeline import Pipeline
>>> from etna.models import NaiveModel
>>> from etna.transforms import AddConstTransform
>>> model = NaiveModel(lag=1)
>>> transforms = [AddConstTransform(in_column="target", value=1)]
>>> pipeline = Pipeline(model, transforms=transforms, horizon=3)
>>> pipeline.set_params(**{"model.lag": 3, "transforms.0.value": 2})
Pipeline(model = NaiveModel(lag = 3, ), transforms = [AddConstTransform(in_column = 'target', value = 2, inplace = True, out_column = None, )], horizon = 3, )
