Encoder and decoder layers. To complement the analysis presented in Sec. 4.3, we also investigate the performance of the M2 Transformer when changing the number of encoding and decoding layers. As our model can deal with a different number of encoding and decoding layers, we also experimented with non symmetric encoding-decoding architectures, without however noticing significant improvements in performance.
