no longer a convex operator because composition of two convex operators isn't necessarily convex okay so so this is gonna so we're just going to call this in a fine spline operator it remains continuous but it doesn't have this max affine spline property anymore I just as an aside if you wanted the overall net to be convex it's pretty easy to constraint to show that all you need to do is just ensure that the all of the weights in the second layer and onward are positive number right that guarantees that the overall
