Abstract：To improve prediction accuracy, a stacking integration framework in machine learning is employed to learn label distribution through multiple classifiers, and a heterogeneous ensemble learning algorithm based on label distribution learning(HELA-LDL) is proposed. A two-layer model framework is constructed, and the sample data are combined through the first layer structure to integrate the learning results of each classifier. Finally, the fusion results are input to the second layer classifier as the original feature, and the labels are predicted to be a label distribution with confidence. Comparative experiments on specialized datasets show that HELA-LDL is superior to other algorithms in various scenes. The stability analysis further illustrates the effectiveness of HELA-LDL.
