Attention Is All You Need

Ashish Vaswani, Noam Shazeer, Niki Parmar, Jakob Uszkoreit, Llion Jones...

The dominant sequence transduction models are based on complex recurrent or convolutional neural networks that include an encoder and a decoder.

Architecture Summary: We show that such architectures can connect encoders and decoders entirely through multi-head self-attention mechanisms, dispensing with recurrence and convolutions entirely.

Experiments on two machine translation tasks show these models to be superior in quality while being more parallelizable and requiring significantly less time to train.
