update rule does ultimately is it minimizes what's called an energy so every type of hopfield network is associated with an energy function and this the energy function of the modern hopfield network for binary strings is this energy function right here so with x x is the pattern um the pattern this is the kind of state of the hopfield network and so these are the the whatever is stored in the network and then design here is the query that you enter into the network and then the energy here tells you this quantity you have to minimize this
