Because the AGCN effectively encodes the dependency structures of sentences through GCN using attention-based pruning, our model explicitly detects relations between two drugs for a given sentence. The baselines primarily employ … WebSelf-attention guidance. The technique of self-attention guidance (SAG) was proposed in this paper by Hong et al. (2024), and builds on earlier techniques of adding guidance to image generation.. Guidance was a crucial step in making diffusion work well, and is what allows a model to make a picture of what you want it to make, as opposed to a random …
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.
