Layers which introduce new dynamic sequence lengths - rwth-i6/returnn GitHub Wiki

This is a list of layers which (potentially) create new (dynamic) sequence lengths (and thus new dimension tags).

  • ConvLayer
  • TransposedConvLayer
  • WindowLayer
  • PoolLayer
  • PadLayer
  • ResizeLayer
  • PrefixInTimeLayer
  • PostfixInTimeLayer
  • SliceLayer
  • SliceNdLayer
  • MergeDimsLayer
  • SplitDimsLayer
  • UnflattenNdLayer
  • RepeatLayer
  • TimeChunkingLayer
  • RemoveLayer
  • RecLayer with search
  • EditDistanceTableLayer
  • MaskedComputationLayer
  • RangeFromLengthLayer
  • RangeLayer

(Related is the list of layers with special behavior on dynamic spatial axes.)
