The main notations used in Fig. 4.

№	Notation	Explanation
1		The dataset with the primary 4 inputs attributes
2		The predicted output of the enhanced input-doubling method for the i-Zone after first level of the enhanced ensemble
3	The enhanced input-doubling method	A weak predictor at the first level of the enhanced cascade ensemble
4	GRNN	General Regression Neural Network – a weak predictor at the second level of the enhanced cascade ensemble
5		New training dataset for the second level of the cascade ensemble that contains predicted output of the enhanced input-doubling method for each 3 Zones
6		The final predicted output of the enhanced ANN-based ensemble method for the i-Zone
