The Neural Data Router: Adaptive Control Flow in Transformers Improves Systematic Generalization. (arXiv:2110.07732v4 [cs.LG] UPDATED)

Despite progress across a broad range of applications, Transformers have
limited success in systematic generalization. The situation is especially
frustrating in the case of algorithmic tasks, where they often fail to find
intuitive solutions that route relevant information to the right node/operation
at the right time in the grid represented by Transformer columns. To facilitate
the learning of useful control flow, we propose two modifications to the
Transformer architecture, copy gate and geometric attention. Our novel Neural
Data Router (NDR) …
