Subject Re: DML example on main SystemML website
Date Thu, 17 Dec 2015 00:16:12 GMT

We can use the Poisson nonnegative matrix factorization example from last
week's webcast:
   i = 0
   while(i < max_iterations) {
       H = (H * (t(W) %*% (V/(W%*%H + epsilon))))/ t(colSums(W))
       W = (W * ((V/(W%*%H) + epsilon) %*% t(H)))/ t(rowSums(H))
       i = i + 1;
   }

Sound ok to everyone?

Fred

Subject:	DML example on main SystemML website



Hi,

I think the main SystemML website at http://systemml.incubator.apache.org/
needs to be updated so that the DML example is an actual algorithm or at
least a fragment of an algorithm.

Does anyone have a recommendation for a short, concise example that shows
the power of DML?

Thanks!
Deron
