### The Behavioral Rate of Fine-Tuning: Compression as a Measure of Useful Information

Joey David, Paul Caillon, Alexandre Allauzen · Under review

[arXiv](https://arxiv.org/abs/2611.06598) · [GitHub](https://github.com/joey-david/fineqcomp)

### Master's thesis · Information Constraints in Fine-tuning and Reasoning Language Models

Joey David · M2 IASD, PSL · Highest honours band · Supervised by Paul Caillon and Alexandre Allauzen

How much information must a model acquire or keep for a learned behavior to survive fine-tuning or multi-step reasoning? The fine-tuning half was later developed into [The Behavioral Rate of Fine-Tuning](https://joeydavid.fyi/research/index.md), now on arXiv.
