what is the mean of gp assumption what justifies the zero mean assumption for gaussian processes? what justify zero mean assumption gaussian what justifies the zero mean assumption why do you not lose generality when you make the zero mean assumption which assumption is justified for gaussian processes? what is gp mean assumption why would you make a zero mean assumption why is it necessary to make a mean assumption when the mean is zero gaussian process why is zero mean assumption necessary what justifies the zero mean assumption for gaussian processes? what is the mean of a gp mean assumption why do you not lose generality when you make a zero mean assumption why do we not lose generality when we make a zero mean assumption why do you think the mean should be zero for ganssian processes why does the gaussian process have zero mean? why do you not lose generality when there is a zero mean assumption why does the gp have a zero mean what is gaussian process mean why do gaussian processes assume zero mean functions
