Gaussian mixture models as a proxy for interacting language models

Edward L. Wang, Mohammad Sharifi Kiasari, Tianyu Wang +4

Large language models (LLMs) are powerful tools that, in a number of settings, overlap with the results of human pattern recognition and reasoning. Retrieval-augmented generation (…

SIGMA: Scalable Spectral Insights for LLM Model Collapse

Yi Gu, Lingyou Pang, Xiangkun Ye +4

The rapid adoption of synthetic data for training Large Language Models (LLMs) has introduced the technical challenge of "model collapse"-a degenerative process where recursive tra…

Taming Variability: Randomized and Bootstrapped Conformal Risk Control for LLMs

Lingyou Pang, Lei Huang, Jianyu Lin +3

We transform the randomness of LLMs into precise assurances using an actuator at the API interface that applies a user-defined risk constraint in finite samples via Conformal Risk…

Unsupervised Conformal Inference: Bootstrapping and Alignment to Control LLM Uncertainty

Lingyou Pang, Lei Huang, Jianyu Lin +4

Deploying black-box LLMs requires managing uncertainty in the absence of token-level probability or true labels. We propose introducing an unsupervised conformal inference framewor…

LLM Web Dynamics: Tracing Model Collapse in a Network of LLMs

Tianyu Wang, Akira Horiguchi, Lingyou Pang +1

The increasing use of synthetic data from the public Internet has enhanced data usage efficiency in large language model (LLM) training. However, the potential threat of model coll…

Investigating social alignment via mirroring in a system of interacting language models

Harvey McGuinness, Tianyu Wang, Carey E. Priebe +1

Alignment is a social phenomenon wherein individuals share a common goal or perspective. Mirroring, or mimicking the behaviors and opinions of another individual, is one mechanism…
