Application of Multilabel Learning Using the Relevant Feature for Each Label in Chronic Gastritis Syndrome Diagnosis

الملخص EN

Background.

In Traditional Chinese Medicine (TCM), most of the algorithms are used to solve problems of syndrome diagnosis that only focus on one syndrome, that is, single label learning.

However, in clinical practice, patients may simultaneously have more than one syndrome, which has its own symptoms (signs).

Methods.

We employed a multilabel learning using the relevant feature for each label (REAL) algorithm to construct a syndrome diagnostic model for chronic gastritis (CG) in TCM.

REAL combines feature selection methods to select the significant symptoms (signs) of CG.

The method was tested on 919 patients using the standard scale.

Results.

The highest prediction accuracy was achieved when 20 features were selected.

The features selected with the information gain were more consistent with the TCM theory.

The lowest average accuracy was 54% using multi-label neural networks (BP-MLL), whereas the highest was 82% using REAL for constructing the diagnostic model.

For coverage, hamming loss, and ranking loss, the values obtained using the REAL algorithm were the lowest at 0.160, 0.142, and 0.177, respectively.

Conclusion.

REAL extracts the relevant symptoms (signs) for each syndrome and improves its recognition accuracy.

Moreover, the studies will provide a reference for constructing syndrome diagnostic models and guide clinical practice.
