📢 I am looking for a postdoc for the next academic year! (Due to the funding source, US persons preferred) Interested in multimodal LLMs and their application to education domains (as well as multilinguality, cross-lingual, and low-resource learning)? If yes, send me a message here or an email!

Fucking hell... Seriously, there's no going back from this. If it were not from Haaretz, nobody would believe it. Worse part? Nobody fucking cares. archive.ph/NVG4p#select...
A recently discharged Division 252 officer describes the arbitrary nature of this boundary: "For the division, the kill zone extends as far as a sniper can see." But the issue goes beyond geography. "We're killing civilians there who are then counted as terrorists," he says. "The IDF spokesperson's announcements about casualty numbers have turned this into a competition between units. If Division 99 kills 150 [people], the next unit aims for 200."

These accounts of indiscriminate killing and the routine classification of civilian casualties as terrorists emerged repeatedly in Haaretz's conversations with recent Gaza veterans.

We had a great discussion with @robertlemos.bsky.social from Dark Reading about our new paper "Hacking Back the AI-Hacker: Prompt Injection as a Defense Against LLM-driven Cyberattacks"(arxiv.org/abs/2410.20911). Mantis turns the hardness of dealing with prompt injections into an opportunity!

Meet Birdie 🐤! Our EMNLP 2024 paper boosts SSMs like Mamba and Hawk on long-range, context-heavy tasks, closing the gap with Transformers. Proud to work with @jimmysmith1919.bsky.social, @antonisa.bsky.social, & Amarda Shehu. 📄 Paper: arxiv.org/abs/2411.01030 💻 Code: github.com/samblouir/bi...
The multi-number phonebook retrieval task entails retrieving several phone numbers from a phonebook at once, given names.

Hawk trained using Birdie strongly outperforms Hawk trained using Next Token Prediction on the multi-number phonebook retrieval task.

Hawk trained using Next Token Prediction performs just above random guessing when retrieving 1 and 4 phone numbers, and falls to random performance when retrieving more than 4 phone numbers.

In contrast, Hawk trained using Birdie gets 100% accuracy when retrieving 1 phone number. That 100% score slowly decays to about 80% accuracy when retrieving up to 32 phone numbers simultaneously.

Two Transformers are included, one trained using Birdie, and the other trained using Next Token Prediction. They both always achieve about 100% accuracy, even when retrieving 32 phone numbers.

Are there any resources for helping introverted students navigate the craziness that is conference attendance, so that they make the most of it? I mean, I can tell my students to "go talk to people", but I'm looking for something more comprehensive. I (extrovert advisor) am struggling.
