case when I put that gives us the basically the compatibility between the two inputs the two values that we give it we can use it to predict you know I'll give you a value of y2 and then buy gradient descent you can find or buy some search our method you can you can find the two values that produce a low energy on the output and they correspond to the two values of by one that are compatible way to okay so that's that's how inference works in those in those systems the system doesn't produce an output it only has
