Reading Group

This page is dedicated to the NLP reading group @ Université de Lorraine. Meetings are scheduled every other Thursday.

This reading group is a spiritual child of last year's reading group, organized by Hoa Le. You can find all the relevant information on that previous reading group here.

One of the goals of this reading group is to provide a space dedicated to discussion for the different NLP labs across Nancy (Synalp, Atilf, ...). To that end, we try to make the presentations as inclusive as possible.

If you'd like to present something, but can't think of a paper to present, there's a spreadsheet with some suggestions. The sheet is editable: don't hesitate to add a suggestion yourself!

Session of Feb 14, 19

Presented by: Timothee Mickus
Paper presented: BERT: Pre-training of Deep Bidirectional Transformers for Language Understanding (link)

A recent advance in the field of word embeddings is the rise of contextualized embeddings. This first session of the reading group was dedicated to one of the most popular contextual embedding architecture, BERT.

BERT is also related to the Transformer architecture of Vaswani and colleagues. See also the Transformer-XL of Dai and al. Here's a github of variations on the Transformer.

Paper presented: No Training Required: Exploring Random Encoders for Sentence Classification (link)
Download slides: link

Sentence embeddings have been a focus of research over the past few years, with new algorithms, datasets and benchmarks. The paper for this second session takes a step back and tries to evaluate how much these sentence embeddings actually gain over random methods.
