Perceiving Longer Sequences With Bi-Directional Cross-Attention Transformers

Markus Hiller, Krista A. Ehinger, Tom Drummond

We present a novel bi-directional Transformer architecture (BiXT) which scales linearly with input size in terms of computational cost and memory consumption, but does not suffer t…
