There has also been a lot of interest in combining CNNs with different forms of self-attention [2,32,48,31,3,17,39]. SASA [31] and SAN [48] deploy a local-attention layer

WebOutline of machine learning. v. t. e. In artificial neural networks, attention is a technique that is meant to mimic cognitive attention. The effect enhances some parts of the input data while diminishing other parts — the motivation being that the network should devote more focus to the small, but important, parts of the data.

Webtuning the cross-attention layers while keeping the encoder and decoder fixed results in MT quality that is close to what can be obtained when fine-tuning all parameters (§4). Evidence also sug-gests that fine-tuning the previously trained cross-attention values is in fact important—if we start with randomly initialized cross-attention ...
