  • Fractionally strided convolution
  • Transposed convolution
    • Like a deep interpolation
  • Convolution with a fractional input stride
  • Up-sampling is convolution 'in reverse'
    • Not an actual inverse convolution
  • For scaling up by a factor of f
  • Could specify kernel
    • Or learn
  • Can have multiple upconv layers

  • Equivalent operation with a flattened input
    • Row per kernel location
  • Many-to-one operation
