WitrynaHowever, RNN attention-based methods are sometimes hard to converge on account of gradient vanishing/exploding during training, and RNN cannot be computed in parallel. To remedy this issue, we propose a Swin Transformer-based encoder-decoder mechanism, which relies entirely on the self attention mechanism (SAM) and can be computed in … Witryna11 maj 2024 · In this work, we propose a local self-attention which considers a moving window over the document terms and for each term attends only to other terms in the same window. This local attention incurs a fraction of the compute and memory cost of attention over the whole document. The windowed approach also leads to more … WitrynaFirst, we investigated the network performance without our novel parallel local-global self-attention, which is described in Section 3.1.
