coherence optimization

Gold definitionUpdated Apr 2, 2026

Definition

Coherence optimization is a theoretical framework unifying various language model self-improvement methods, demonstrating they find a maximally compressible and predictable context-to-behavior mapping. It's proven equivalent to description-length regularization, offering an optimal approach for semi-supervised learning.

At a glance

Executive summary

Coherence optimization is a new theory explaining how AI language models can improve their accuracy without needing human feedback. It shows that various self-improvement methods are essentially finding the simplest and most predictable ways for the model to respond to different inputs. This approach is proven to be ideal for learning with limited data.

TL;DR

A new theory explains how AI models can get better on their own by finding the most consistent and predictable ways to behave, especially useful when there's not much training data.

Key points

Unifies and explains various feedback-free self-improvement methods in LMs by finding a maximally compressible and predictable context-to-behavior mapping.
Solves the problem of theoretically understanding why LMs can improve accuracy without external supervision, sometimes matching supervised fine-tuning.
Primarily used by researchers in theoretical machine learning, large language models, and semi-supervised learning to design more effective self-improving AI.
Provides a theoretical foundation for feedback-free self-improvement, contrasting with methods requiring extensive external supervision or 'golden' datasets.
Represents a significant research trend towards more autonomous and data-efficient learning paradigms for large language models.

Use cases

Developing LLMs that can improve their performance and accuracy without requiring costly human-labeled datasets.
