so this we don't know yet and you can you know look at other things for instance this um this case of two clusters is quite interesting because if you don't do the stochastic gradient descent but fulbright guiding this and that would be this this picture that is of course just a special case of the equations that i just wrote it has this specular behavior that if you initialize so r is the variance at initialization if you initialize at zero with really small variance then after one iteration you reach the base optimal error
