Great minds think alike! Alan Turing cracked Enigma in WWII; Brad Efron asked how many words Shakespeare knew. They used the same method. We use this method for LLM evaluation—to evaluate certain unseen capabilities of LLMs: arxiv.org/abs/2506.02058

Evaluating the Unseen Capabilities: How Many Theorems Do LLMs Know?
Accurate evaluation of large language models (LLMs) is crucial for understanding their capabilities and guiding their development. However, current evaluations often inconsistently reflect the actual ...

A (not so) new paper on #LLM alignment from a social choice theory viewpoint: arxiv.org/abs/2503.10990 It reveals fundamental impossibility results concerning representing (diverse) human preferences.

Statistical Impossibility and Possibility of Aligning LLMs with Human Preferences: From Condorcet Paradox to Nash Equilibrium
Aligning large language models (LLMs) with diverse human preferences is critical for ensuring fairness and informed outcomes when deploying these models for decision-making. In this paper, we seek to ...

We posted a paper on optimization for deep learning: arxiv.org/abs/2505.21799 Recently there's a surge of interest in *structure-aware* optimizers: Muon, Shampoo, Soap. In this paper, we propose a unifying preconditioning perspective, offer insights into these matrix-gradient methods.

PolarGrad: A Class of Matrix-Gradient Optimizers from a Unifying Preconditioning Perspective
The ever-growing scale of deep learning models and datasets underscores the critical importance of efficient optimization methods. While preconditioned gradient methods such as Adam and AdamW are the ...

Do Large Language Models (Really) Need Statistical Foundations?
Large language models (LLMs) represent a new paradigm for processing unstructured data, with applications across an unprecedented range of domains. In this paper, we address, through two arguments, wh...

I wrote a post on how to connect with people (i.e., make friends) at CS conferences. These events can be intimidating so here's some suggestions on how to navigate them I'm late for #ICLR2025 #NAACL2025, but in time for #AISTATS2025 #ICML2025! 1/3 kamathematics.wordpress.com/2025/05/01/t...

Tips on How to Connect at Academic Conferences
I was a kinda awkward teenager. If you are a CS researcher reading this post, then chances are, you were too. How to navigate social situations and make friends is not always intuitive, and has to …

Machine learning has led to predictive algorithms so obscure that they resist analysis. Where does the field of traditional statistics fit into all of this? Emmanuel Candès asks the question, “Can I trust this?” Tune in to this week’s episode of “The Joy of Why” listen.quantamagazine.org/jow-321-s

Knew nothing about bluesky until today. Immediately stop using X or gradually migrate to bluesky? Is there an optimal switching strategy?
