skcriteria.core.methods module

Core functionalities of scikit-criteria.

class skcriteria.core.methods.SKCDecisionMakerABC

Bases: skcriteria.core.methods.SKCMethodABC

Mixin class for all decisor based methods in scikit-criteria.

evaluate(dm)

Validate the dm and calculate and evaluate the alternatives.

Parameters

dm (skcriteria.data.DecisionMatrix) – Decision matrix on which the ranking will be calculated.

Returns

Ranking.

Return type

skcriteria.data.RankResult

class skcriteria.core.methods.SKCMatrixAndWeightTransformerABC(target)

Bases: skcriteria.core.methods.SKCTransformerABC

Transform weights and matrix together or independently.

The Transformer that implements this mixin can be configured to transform weights, matrix or both so only that part of the DecisionMatrix is altered.

This mixin require to redefine _transform_weights and _transform_matrix, instead of _transform_data.

property target

Determine which part of the DecisionMatrix will be transformed.

class skcriteria.core.methods.SKCMethodABC

Bases: object

Base class for all class in scikit-criteria.

Notes

All estimators should specify:

• _skcriteria_dm_type: The type of the decision maker.

class skcriteria.core.methods.SKCTransformerABC

Bases: skcriteria.core.methods.SKCMethodABC

Mixin class for all transformer in scikit-criteria.

transform(dm)

Perform transformation on dm.

Parameters

dm (skcriteria.data.DecisionMatrix) – The decision matrix to transform.

Returns

Transformed decision matrix.

Return type

skcriteria.data.DecisionMatrix

class skcriteria.core.methods.SKCWeighterABC

Bases: skcriteria.core.methods.SKCTransformerABC

Mixin capable of determine the weights of the matrix.

This mixin require to redefine _weight_matrix, instead of _transform_data.
