[Nov 4th 2020] LabMeeting: Introduction to Transformers

Conference Meeting

In the last decade most of the advances in NLP were achieved by learning textual representations with unsupervised Language Modeling-related tasks on large corpora.
Recently, this principle was pushed even further with transformers, where the scales of datasets and model sizes have grown by orders of magnitude wrt previous sota sequence-to-sequence recurrent models. Since their introduction, transformers have wiped out the previous state-of-the-art in almost any NLP problem.
In this seminar I present how these models work, what are the differences wrt to RNNs in terms of computational complexity and scalability issues, and finally their limitations.
