Data-based structure selection for unified discrete grey prediction model

作者：

Highlights：

• A novel discrete grey polynomial model is proposed.

• The proposed model unifies the univariate discrete grey models.

• An algorithm is presented to select the optimal model structure adaptively.

• Matrix decomposition technique is adopted to provide a simpler paradigm for property analysis.
