    Generally we deal with two types of forecasting; point and interval. With statistical method of forecasting (like ARIMA), we can perform interval prediction considering uncertainty of prediction. But what about doing the same with machine learning techniques like ANN and SVM?

    Why Major channel models such as WINNIER II, ITU, etc. depend on log-distance equation to model the signal pathloss (the average attenuation of the signal), according to the equation: PL(Distance) = PL_reference + 10 x alpha x Log(Distance). Is it the best way to represent the relation between the Pathloss and distance?

    How can we separate eddy current effect and the magnetic after-effect in carbon steel, only measure the relaxation time caused by eddy current effect or only measure the time caused by magnetic domain movement?
