I am attempting to Round up the output Vector of a Neural Network layer to prepare it for the next layer Ex. Layer output {.1.,2.2,3.3} and I need it to be a Vector of Integers for the next layer.

I have tried this, Round@@LinearLayer[3]. But it does not work.

Any suggestions would be appreciated.

Thank You

Michel

ElementwiseLayer[Ceiling] rounds up, ElementwiseLayer[Round] rounds to the nearest integer. This layer also accepts arbitrary compositions of a subset of Mathematica functions (see documentation for more details).

  • $\begingroup$ Hello, When I run this: a = ElementwiseLayer[Round] a[{1.3, 4.6}] MMA12 still gives reals {2., 5.} Am I missing some setting? $\endgroup$ Jan 7, 2020 at 12:48
  • $\begingroup$ It's just how Mathematica's nerual functionality works internally: almost everything is floating point. For example, OrderingLayer should in theory return integers, just like Ordering does, but in fact its output is floating point. This is usually not a problem for further layers, though. $\endgroup$
