cool analogy for AI & jobs: - when ATMs came, the number of bank tellers rose, bc ATMs lowered the cost of running bank branches, so more branches opened - but in the 2010s, the number of bank tellers plummetted, bc mobile banking made branches unnecessary

This is some legit really impressive work!!

📢Thrilled to introduce ATLAS 🗺️: the largest multilingual scaling study to-date—we ran 774 exps (10M-8B params, 400+ languages) to answer: 🌍 Is scaling diff by lang? 🧙‍♂️ Can we model the curse of multilinguality? ⚖️ Pretrain vs finetune from checkpoint? 🔀 X-lingual transfer scores across langs? 1/🧵

They say it's because (1) test sets have become more challenging, (2) include more lang pairs, (3) are longer, and (4) used ESA instead of MQM. But we need an ablation study!

in Vienna for ACL, presenting Tulun, a system for low-resource in-domain translation, using LLMs Tuesday @ 4pm Working w 2 real use cases: medical translation into Tetun 🇹🇱 & disaster relief speech translation in Bislama 🇻🇺

Cool paper, at the intersection of grammar and LLM interpretability. I like that they use linguistic datasets for their experiments, then get results that can contribute to linguistics as a field too! (on structural priming vs L1/L2)

My paper with @tylerachang.bsky.social and @jamichaelov.bsky.social will appear at #ACL2025NLP! The updated preprint is available on arxiv. I look forward to chatting about bilingual models in Vienna!

Our paper on who uses tetun.org, and what for, got published at the LoResMT 2025 workshop! An emotional paper for me, going back to the project that got me into a machine learning PhD in the first place.

(3) The vast majority of usage is on mobile (over 90% of users / over 80k devices) Takeaway: publishing MT model in mobile apps is probably more impactful than setting up a website / HuggingFace space.

We find that (1) a LOT of usage is for educational purposes (>50% of translated text) --> contrasts sharply with Tetun corpora (e.g. MADLAD), dominated by news & religion. Takeaway: don't evaluate MT on overrepresented domains (e.g. religion)! You risk misrepresenting end-user exp.

(2) Translation into Tetun is in higher demand (by >2x) than translation from Tetun Takeaway for us MT folks: focus on translation into low-res langs, harder but more impactful

My favourite ICLR paper so far. Methodology, findings and their implications are all very cool. In particular Fig. 2 + this discussion point:

Seth Aycock@sethjsa.bsky.social

Pleased to announce our paper was accepted at ICLR 2025 as a Spotlight! I will present our poster on Saturday April 26, 3-5pm, Poster #241. Hope to see you there! arxiv.org/abs/2409.19151

Incredible paper, finding that large companies can game the LMArena through statistical noise (via many model submissions), over-sampling of their models, and overfitting to Arena-style prompts (without real gains on model reasoning) The experiments they run to show this are pretty cool too!

Sara Hooker@sarahooker.bsky.social

It is critical for scientific integrity that we trust our measure of progress. The @lmarena.bsky.social has become the go-to evaluation for AI progress. Our release today demonstrates the difficulty in maintaining fair evaluations on the Arena, despite best intentions.

Cool summary of issues with multilingual LLM eval, and potential solutions! If you're doubtful of all these non-reproducible evals on translated multiple choice questions, this paper is for you

📖New preprint with Eleftheria Briakou @swetaagrawal.bsky.social @mziizm.bsky.social @kocmitom.bsky.social! arxiv.org/abs/2504.11829 🌍It reflects experiences from my personal research journey: coming from MT into multilingual LLM research I missed reliable evaluations and evaluation research…

Our paper on generating bilingual example sentences with LLMs got best paper award @ ALTA in Canberra! arxiv.org/abs/2410.03182 We work with French / Indonesian / Tetun, find that annotators don't agree about what's a "good example", but that LLMs can align with a specific annotator.

You are up to date.
