SUMMARY:Natural Language Processing\, Julien Boelaert (CERAPS\, Université de Lille)
DESCRIPTION:  \n\n\n\n  \n  \nSCHEDULE\n  \nMonday\n  \n13th November 2023 \n20th November 2023\n  \nFrom 13:00 to 16:15\n  \nRoom 2033\n\n\n  \nThursday\n  \n16th November 2023 \n23rd November 2023\n  \nFrom 13:00 to 16:15\n  \nRoom 2033\n\n\n\nAims and objectives\nThe aim of this course is to provide an introduction to the main contemporary methods for natural language processing\, and to illustrate them with recent uses of text as data in social sciences. \nNatural language processing has made giant steps during the last decade\, as illustrated in 2023 by the resounding popularity of chatGPT. In addition\, text corpora have become increasingly available for exploitation by social scientists\, be it through digitization of originally paper sources (eg. Parliamentary sessions transcripts\, printed newspapers\, books\, historical sources\, …) or audio sources (through automatic transcription)\, or through the advent of natively digital sources (from social media\, online newspapers\, …). \nThe course will start with the standard (aka pre-neural) methods of the late 20th century\, based on large document-feature matri-ces. We will then cover more recent developments: word embeddings (for improved NLP\, or studies about bias in text corpora)\, topic modeling with Latent Dirichlet Allocation (unsupervised detection of topics)\, and Transformer models (current state of the art\, BERT- and GPT-like models). Each session will comprise a theoretical lecture\, and applied examples on R or python. \n\n

SUMMARY:Olivier Tercieux (PSE)  - “Optimal Queue Design”
DESCRIPTION:Séminaire Microéconomie : Tous les mercredis\n Heure : 12h15 – 13h30 \nDate : 15/11/2023 \nSalle : 3001 \nOlivier Tercieux (PSE) – “Optimal Queue Design” \nAbstract : \nWe study the optimal method for rationing scarce resources through a queue system. The designer controls agents’ entry into a queue and their exit\, their service priority—or queueing discipline—as well as their information about queue priorities\, while providing them with the incentive to join the queue and\, importantly\, to stay in the queue\, when recommended by the designer. Under a mild condition\, the optimal mechanism induces agents to enter up to a certain queue length and never removes any agents from the queue; serves them according to a first-come-first-served (FCFS) rule; and provides them with no information throughout the process beyond the recommendations they receive. FCFS is also necessary for optimality in a rich domain. We identify a novel role for queueing disciplines in regulating agents’ beliefs and their dynamic incentives\, and uncover a hitherto unrecognized virtue of FCFS in this regard. \nhttps://docs.google.com/document/d/1sJXsOmdgucyN5J9tBlBXYCDls7UNrzf9y7QFbJOq40c/edit \nOrganisateurs : \nJulien COMBE (Pôle d’Economie du CREST) \n​​Yves Le YAOUNQ (Pôle d’Economie du CREST) \n​​Matias NUNEZ (Pôle d’Economie du CREST) \nCommanditaires :\n CREST \n
