Analytical Redundancy of Variable Cycle Engine Based on Proper Net considering Multiple Input Variables and the Whole Engine’s Degradation

Table 4

Comparison between over inner-level data fusion structure and interlevel data fusion structure.

Net	Average relative error/%	Layers	Training time/min (10 epochs)	Calculation time/s (1000 points)	Macroscopic structure
Proper net	0.84	49	25	0.3645
Google-alter net	1.74	31	12	0.2117
Mobile-alter net	1.22	63	52	0.3694
