First, the random parameters from input layer to hidden layer, wd,L and bL, are both fixed random vectors originating from a given interval, [-λ, λ]. Second, the number of hidden nodes, L, is given before the network training and it does not change during the network training. Third...
Group I filters represent typical nominal filters, showing relatively flat FE behavior over the course of about 2 years of filter usage. Since observations in Figure 5 show that FE for different sizes did not change dramatically over the course of the experiment, the results in Figure 8 suggest...
Based on this reference, a time interval (orange) is indicated, where the location and the width of the interval is dependent on the constellation as well as the size and shape of the reflecting object. Finally, the resulting, subtracted CIR 𝒉 sub𝑡𝑠(𝑡)h¯tssub(t) is given ...
