1/ Pattern matching has been left ambiguous for so long. Our precise formalization pinpoints its predictive power on composition tasks! 📣 Check out our ICLR 2026 paper: 1️⃣ Sharp sample complexity bound for 2-hop task; 2️⃣ Some unexpectedly hard composition tasks: CoT won’t help.

🤔How can we systematically assess an LM's proficiency in a specific capability without using summary measures like helpfulness or simple proxy tasks like multiple-choice QA? Introducing the ✨BiGGen Bench, a benchmark that directly evaluates nine core capabilities of LMs.

❓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. 📄arxiv.org/abs/2410.01380

I’m happy to share our Janus work has been accepted to #NeurIPS2024 ! Thank you for co-leading this project @suehpark 🥳 See you in Vancouver 🇨🇦
🚨 New LLM personalization/alignment paper 🚨 🤔 How can we obtain personalizable LLMs without explicitly re-training reward models/LLMs for each user? ✔ We introduce a new zero-shot alignment method to control LLM responses via the system message 🚀

🔬 We further investigate the reliance on memorization of training data, showing less reliance on solving D3 questions than simple factual recall (D1). Through this, we also reveal that forward and backward discrepancies in large models originate from distinct types of failures (25% vs. 75% of 70B models, higher % memorizes more). [🧵7 / 10]

🪜 To enhance reasoning, we guide models through structured, multi-turn interactions, consistently improving performance of most models. This highlights the importance of intermediate steps in complex reasoning. [🧵8 / 10]

📊 We tested various instruction-tuned LLMs like LLaMA 2, LLaMA 3, Mistral, and Mixtral, ranging from 7B to 70B parameters. Our findings show smaller models have larger discrepancies, while larger models struggle from discrepancies less. [🧵6 / 10]

📐 Now how to evaluate? Our method involves measuring forward reasoning gaps (differences in performance on simpler vs. complex questions) and backward discrepancies (success on complex questions but struggles with simpler ones). This gives a comprehensive view of LLMs' reasoning skills. [🧵5 / 10]

📚 Introducing DepthQA: a collection of questions and answers derived from human-written scientific D3 questions in the TutorEval dataset. D2 and D1 questions are generated using GPT-4 Turbo, under a carefully designed construction pipeline and postprocessing in order to ensure accuracy of the content and reasoning graph representation. Various types of reasoning processes are observed! [🧵4 / 10]

⛓️ To tackle this, we propose breaking down complex questions into a graph structure, with each node representing a specific depth of understanding: recall (D1), application (D2), and strategic thinking (D3). Our approach emphasizes accumulating and integrating knowledge to solve real-world problems effectively. [🧵3 / 10]

❓Complex questions often require various reasoning processes beyond simply aggregating facts. Take this question as an example: "Why does ReLU training take less time than sigmoid or tanh training?". One must not only *recall* what an activation function is, but also *compare* the characteristics of activation functions and understand the *causal* relationship between gradients and training speed.
