6. def computePrevDelta(nextDelta: DenseMatrix[Double], input: DenseMatrix[Double], delta: DenseMatrix[Double]): Unit

   

   Computes the delta for back propagation.

   Computes the delta for back propagation. Delta is allocated based on the size provided by the LayerModel implementation and the stack (batch) size. Developer is responsible for checking the size of prevDelta when writing to it.
