           It was fun/happy to collaborate with you, Sara🤟🙌 Our paper/dataset on Knowledge Conflict is here! See you in Miami🌴 
           🚨New Benchmark Alert🚨 Our paper accepted to Findings of EMNLP 2024🌴 introduces a new dataset, DynamicQA! DynamicQA contains inherently conflicting data (both disputable🤷♀️ & temporal🕰️) crucial to studying LM’s internal memory conflict. Work with @hayu204 🥳 #EMNLP2024 #NLProc

             🌐 What we found 1️⃣ LLMs encode Western-dominance bias and cultural flattening in their internals. 2️⃣ Internalized cultural biases do not necessarily align with extrinsic biases. 3️⃣ Low-resource cultures are less affected by these biases, likely due to limited training data.

             ✨ What we did - Propose Culturescope, an MI-based method that probes the internal cultural knowledge space of LLMs - Create multiple-choice questions with cultural hard-negatives to test how internalized cultural biases affect downstream tasks

             🎉 Excited to share that Knowledge Entropy has been accepted to #ICLR2025 as an oral presentation! Check out if you are interested in why LLMs lose their ability to acquire new knowledge during pretraining. See you in Singapore! 
           ❓Do LLMs maintain the capability of knowledge acquisition throughout pretraining? If not, what is driving force behind it? ❗Our findings reveal that decreasing knowledge entropy hinders knowledge acquisition and retention as pretraining progresses. 📄  https://t.co/t4mW2VmObw

Existing backward chaining (top-down reasoning) methods are incomplete, leading to suboptimal performance. We build SymBa, a complete neuro-symbolic backward chaining method using SLD-Resolution.
