Podcasts are a popular medium, but data for computational research is limited! We introduce the Structured Podcast Research Corpus (SPoRC - https://t.co/iBd8ZfUSmc), a large, multimodal dataset of English podcasts 🧵

#Tokenization is undeniably a key player in the success story of #LLMs but we poorly understand why.
I want to highlight progress we made in understanding the role of tokenization, developing the core incidents and mitigating its problems. 🧵👇

Curious about using LLMs to simulate conversations? Check out this big collaborative project we did @umsi !
#NLProc

[Suzan Verberne 🤹‍♀️ @suzan]

The 34th edition of Computational Linguistics in The Netherlands (the Dutch-Belgian #NLProc conference) will be held @UniLeiden on August 30

The list of accepted abstracts is on the website and registration is open for everyone interested 💬

🔎What values and opinions do we see when we use 6 LLMs to generate 156,000 responses to 62 political propositions?

Our paper "Revealing Fine-Grained Values and Opinions in Large Language Models" answers this.

📢Is current “human-AI alignment” research clarified and comprehensive? 🤔 We systematically reviewed 400+ papers across HCI, NLP, and ML to develop a framework for 👫<>🤖"Bidirectional Human-AI Alignment", encompassing the dual paths of “Aligning AI to Human” and “Aligning Human to AI”. We also clarified core questions 🎯 of 'what is the alignment goal?', 'with whom to align?', and 'what are the human values?’

Further, we share 👩‍💻 our findings on values and interaction techniques for alignment. Check out the three challenges and potential solutions we envision for future research🌟! #HumanAIAlignment

[1/13] LLMs are increasingly skilled at mimicking human agents in social settings, but have they truly developed a consistent personality? Check out our work accepted to #NAACL2024 where we question the reliability of persona tests applied to LLMs.

BMRS: Bayesian Model Reduction for Structured Pruning

Structured pruning makes neural nets efficient by removing full structures (e.g. neurons).

But how do we know what to prune?

Here's our approach: https://t.co/epxvZFtOJO

@natfriedman Some colleagues and I have been studying the impact of ChatGPT on SO using data on posts, not views: https://t.co/JnLs4PQggU

Besides a big decrease after ChatGPT, we observe a completely flat 2022, and earlier a big bump in activity during early Covid.

[Indira Sen @indiiigosky]

Copenhagen is beautiful &amp; #ic2s2 is amazing, but do you know what’s neither? 🚫 unintended bias towards marginalized people in hate speech detection systems.

Presenting our poster (w/ @hide_yourself @clauwa @IAugenstein) today about how data augmentation can lead to such biases!

[Johannes Wachs @johannes_wachs]

🚨 New working paper!
Are Large Language Models a threat to digital public goods?

@RMaria_drc N. Laurentsyeva and I find a 16% decrease in activity on @StackOverflow since release of #ChatGPT. Decrease is language dependent &amp; reaches 25% by June: https://t.co/JnLs4PQggU

[Jiaxin Pei @jiaxin_pei]

How does annotator identity influence their judgments for NLP tasks? Collaborating with @Prolific, @david__jurgens and I created POPQUORN: a dataset with 45000 annotations on 4 NLP tasks by 1484 annotators with rich demographic information.

It takes 360.000 gallons of water/day to cool a data centre! Exploitation of workers, workplace automation, & mass discrimination of marginalised groups, these are REAL existential risks, not this latest PR stunt, my interview https://t.co/3fzHk0pviL @Independent @oiioxford @BKCHarvard
