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 𝑆 of radii (ra), depths (de), 𝜖_𝑟, and 𝜎 a scattered wave (𝑊_𝑠∈ℝ^𝑝) 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 10-fold cross-validation was employed.
