Attention Pattern
Mechanism that selectively focuses on certain parts of the input data to improve processing efficiency and performance outcomes.
The attention mechanism, particularly in the context of neural networks, enables models to dynamically focus on relevant features of the input data, often in sequence processing tasks like natural language processing (NLP) or image recognition. This method mimics cognitive attention in humans, whereby selective concentration enhances comprehension and decision-making. Attention models adjust the 'focus' based on the task's requirements, improving the model's ability to handle long sequences, integrate context effectively, and even manage multiple input modalities. The transformative impact of attention patterns is most notable in architectures like Transformers, which rely entirely on attention to process inputs without the constraints of sequential dependencies.
The concept of attention in neural networks was initially introduced around the early 2010s, with significant popularity and application following the introduction of the Transformer model in 2017.
Notable early work on attention mechanisms can be attributed to researchers like Bahdanau et al., who in 2014 introduced a form of attention in their neural machine translation system. However, the concept reached a broader audience and saw extensive application across various domains following Vaswani et al.'s introduction of the Transformer architecture in 2017, which utilizes multi-headed self-attention to enhance the model's performance across diverse tasks.
