> This task aims to write a dml script consisting the paramserv function. We
> could easily reuse the MNIST LeNet example and adapt it by creating a
> struct-like model and passing the update function as well as the aggregation
> function. In this case, the update function which will be executed in workers
> should consist of calculating the gradients by walking the batch forward and
> backward steps. And the aggregation function which will be runned in
> parameter server should consist of updating the weights and biases by
> aggregating the received gradients.
