[Hongru Wang @Job Market @HongruWang007]

Actually, we implemented this kind of capability in our AdaCtrl paper three months ago by injecting difficult-aware tags (i.e., easy, hard, adaptive) to trigger different reasoning behaviors of LLMs.

🤯 Multimodal LLMs can be confidently wrong. A single early mistake in perception can lead to a completely incorrect answer.

🚀Introducing our work, MMBoundary, a new framework to make MLLMs aware of their own knowledge boundaries! 🧵

Thrilled to share a major milestone: the culmination of a 15-month project, ATLAS—a new benchmark in event graphs and conceptualization! This journey began with Probase in 2012, evolved through ASER (2019), AbstractATOMIC (2022), and AbsPyramid (2023), and now realizes a decade-long dream of building a web-scale knowledge graph integrating entities, events, and a conceptualization framework. It’s also a tribute to Marvin Minsky’s K-Lines Theory.

I still vividly recall 2012 when I worked with Haixun, including intern Fangting Xia, spent months exploring event semantic primitives and conceptualization, only to pivot due to limitations. Fast forward to the era of large language models, and we’ve finally brought this vision to life!

Someone argued that knowledge graphs are obsolete in the age of large models. We disagree—it’s about having high-quality graphs that scale with these models. That’s why we invested HK$1.5M to process Wikipedia, academic abstracts, and 3% of web data from Dolma, creating a 1B-node graph—the best we could achieve.

While entities cover 70% of factual queries, adding event semantic primitives boosts coverage to 90%. This is why text decomposition is gaining traction. Our extracted knowledge graph excels on complex factual queries like HotpotQA, MMLU, and FELM, making it the largest open-source GraphRAG dataset available.

This work is the result of 10+ students and nearly 10 collaborators pouring their hearts into it. I’m deeply grateful for their contributions to this meaningful milestone, and I hope they’ve gained as much from the journey as I have.

Big shoutout to anyone curious about pushing this further! Parsing the entire web’s data would cost ~HK$40M, and I’d love to collaborate with bold thinkers to make it happen.

We studied both rule-based and model-based verifiers and found that each has unique limitations. Rule-based verifiers are often unreliable, even in math, and are unavailable in many domains.

Model-based verifiers can be easily hacked. In our paper, we construct simple adversarial patterns to successfully crack several open model-based verifiers.

🧐Interestingly, as the community shifts toward generative verifiers, we found them to be far more vulnerable than discriminative ones. This suggests that discriminative verifiers might be more robust against reward hacking in RLVR.

Great to see the wonderful series of work that @WangCarrey has been leading at UIUC. We also had a fun collaboration recently together with my incoming PhD student Shijue. Check out our latest release
