How Well do LLMs Compress Their Own Chain-of-Thought? A Token Complexity Approach

Ayeong Lee, Ethan Che, Tianyi Peng

Chain-of-thought prompting has emerged as a powerful technique for enabling large language models (LLMs) to solve complex reasoning tasks. However, these reasoning chains can be ve…

Data Mixture Optimization: A Multi-fidelity Multi-scale Bayesian Framework

Thomson Yen, Andrew Wei Tung Siah, Haozhe Chen +3

Careful curation of data sources can significantly improve the performance of LLM pre-training, but predominant approaches rely heavily on intuition or costly trial-and-error, maki…

LLM Generated Persona is a Promise with a Catch

Ang Li, Haozhe Chen, Hongseok Namkoong +1

The use of large language models (LLMs) to simulate human behavior has gained significant attention, particularly through personas that approximate individual characteristics. Pers…
