Matrix scaling by network flow
WebOur algorithm is a scaling algorithm. It solves a sequence of more and more refined discretizations. The discretizations are minimum-cost network flow problems with convex … Web22 mrt. 2024 · In the scaling process, we either compress or expand the dimension of the object. Scaling operation can be achieved by multiplying each vertex coordinate (x, y) of the polygon by scaling factor s x and s y to produce the transformed coordinates as (x’, y’). So, x’ = x * s x and y’ = y * s y.

By keeping certain parts of the model in the 32-bit types for numeric stability, the model will have a lower step time and train equally as well in terms of the evaluation metrics such as accuracy.
