A Review of Soft Techniques for Electromagnetic Assessment of Concrete Condition

Figure 3

This figure shows an overview of the detection system employed using the ANN. Firstly, given a set of radii (ra), depths (de), , and a scattered wave ( ) is calculated using FDTD. Afterwards, a dimensional reduction is applied. In the next steep, the expected error is estimated to adapt the Parallel Layer Perceptron network parameters. In this work a -fold cross-validation was employed.
