function in terms of those weights so if we plot in the case again of a two-dimensional weight problem so one of the weights is on the x-axis one of the weights is on this axis and on the z axis we have the loss so for any value of w we can see what the loss would be at that point now what do we want to do we want to find the place on this landscape what are the values of W that we get the minimum loss okay so what we can do is we can just pick a random W pick a random place on this this landscape to start with and from
