Study on Downhole Geomagnetic Suitability Problems Based on Improved Back Propagation Neural Network
Publikováno v:
Electronics; Volume 12; Issue 11; Pages: 2520
The analysis of geomagnetic suitability is the basis and premise of geomagnetic matching navigation and positioning. A geomagnetic suitability evaluation model using mixed sampling and an improved back propagation neural network (BPNN) based on the g
