A Latent Variable Framework for Scaling Laws in Large Language Models

Peiyao Cai, Chengyu Cui, Felipe Maia Polo +6

We propose a statistical framework built on latent variable modeling for scaling laws of large language models (LLMs). Our work is motivated by the rapid emergence of numerous new…

Learning to Choose or Choosing to Learn: Best-of-N vs. Supervised Fine-Tuning for Bit String Generation

Seamus Somerstep, Vinod Raman, Unique Subedi +1

Using the bit string generation problem as a case study, we theoretically compare two standard methods for adapting large language models to new tasks. The first, referred to as su…

Sloth: scaling laws for LLM skills to predict multi-benchmark performance across families

Felipe Maia Polo, Seamus Somerstep, Leshem Choshen +2

Scaling laws for large language models (LLMs) predict model performance based on parameters like size and training data. However, differences in training configurations and data pr…

Limitations of refinement methods for weak to strong generalization

Seamus Somerstep, Ya'acov Ritov, Mikhail Yurochkin +2

Standard techniques for aligning large language models (LLMs) utilize human-produced data, which could limit the capability of any aligned LLM to human level. Label refinement and…

CARROT: A Cost Aware Rate Optimal Router

Seamus Somerstep, Felipe Maia Polo, Allysson Flavio Melo de Oliveira +5

With the rapid growth in the number of Large Language Models (LLMs), there has been a recent interest in LLM routing, or directing queries to the cheapest LLM that can deliver a su…
