Inference
Attention Mechanism
The core technique inside transformers that lets a model weigh the relevance of every token relative to every other token in a sequence.
In depth
The core technique inside transformers that lets a model weigh the relevance of every token relative to every other token in a sequence. Instead of processing input left-to-right, attention computes relevance scores across all positions at once, allowing the model to focus on the most important parts of the context regardless of distance.
Example
In practice, developers reach for Attention Mechanism when they need the capability described above as part of an AI feature or workflow.
