DLM-Scope: Mechanistic Interpretability of Diffusion Language Models via Sparse Autoencoders

One-line Summary

DLM-Scope introduces a sparse autoencoder-based framework for interpreting diffusion language models, showing unique advantages over traditional autoregressive models.

Plain-language Overview

Researchers have developed a new framework called DLM-Scope to help understand how diffusion language models (DLMs) work. These models are a new type of language model that could be better than the traditional ones. By using a tool called sparse autoencoders, the researchers can identify and manipulate features in these models in a way that is easier for humans to understand. Interestingly, this approach seems to improve the performance of DLMs in ways it doesn't for older models, making it a promising direction for future research.
