Introduction to Transformers: an NLP Perspective

arXiv:2311.17633v2 Announce Type: replace Abstract: Transformers have dominated empirical machine learning models of natural language processing. In this paper, we introduce basic concepts of Transformers and present key techniques that form the recent advances of these models. This includes a description of the standard Transformer architecture, a series of model refinements, and common applications. Given that Transformers and related deep learning techniques might be evolving in ways we have never seen, we cannot dive into all the model details or cover all the technical areas. Instead, we

Why this matters
Why now

The publication in arXiv of an introductory paper on Transformers reflects their current dominance in NLP and the ongoing effort to codify and disseminate foundational knowledge in AI.

Why it’s important

This materialization of Transformer concepts as a foundational 'introduction' signals a maturing and rapid mainstreaming of this core AI technology, indicating its expanding influence across various applications and industries.

What changes

The widespread accessibility of foundational Transformer knowledge helps accelerate development, lower barriers to entry for new AI applications, and further embed these architectures into the technological stack.
