down on the energy of the data points and this will have the effect if minimize this you'll have to push up on the energy of every single point in your space okay because to make this small you have to make those energies high because it's negative exponential if you compute the gradient of that last function with respect to the parameters of your energy function you get the expression at the top here which tells you that a step of gradient is going to push down with a unit force on the data point and then the second term says I'm
