A Machine Learning Approach For Simulating Ground Penetrating Radar

Iraklis Giannakis, Antonios Giannopoulos, Craig Warren
2018 2018 17th International Conference on Ground Penetrating Radar (GPR)  
Based on these parameters and the synthetically generated training set, a machine learning framework is trained to predict the resulting A-Scan in real-time.  ...  Through a stochastic parameterisation, each model is expressed using only seven parameters (i.e. the fractal dimension of water fraction, the heigh of the antenna and so on).  ...  The first two layers use sigmoid activation functions while the last layer uses a linear one in order to predict the continuous nature of the compressed A-Scan.  ...
