A power engineering contract data classification and matching method integrating fuzzy mechanism
The data of power engineering contracts exhibit significant heterogeneity and multimodality
and contains a large number of fuzzy concepts. Existing methods have deficiencies in the representation of fuzzy features
multi-modal integration
dimensionality unification
and fuzzy similarity calculation. Therefore
this paper proposes a precise matching method for contract data classification that integrates fuzzy mechanisms. Firstly
a multi-modal data description model based on fuzzy theory is constructed
combining fuzzy sets
membership functions
and 1D-CNN-LSTM to achieve unified representation of fuzzy features and multi-modal features; secondly
a multi-stage feature optimization mechanism based on translation range transformation is designed to eliminate dimensions
reduce high-dimensional data
and filter out redundant features; thirdly
a multi-modal fuzzy rough set classification matching algorithm is proposed
which calculates similarity for different types of features by adapting modulus functions and combines PK-means++ and MMNN algorithms to achieve precise classification matching. Experiments using 10
000 contract data samples from a provincial power company show that the classification accuracy of this method reaches 89.2%
and the F1-score is 88.7%
which is superior to mainstream methods. The three core modules work collaboratively to improve the accuracy and robustness of classification matching
providing technical support for the intelligent management of power engineering contract data.
