A distribution-aware neuron selection method using pairwise overlap coefficients of per-language activation densities identifies more language-specific neurons than existing entropy-based methods.
In Llama-3.1-8B, Qwen3-8B, and Gemma-2-9B, stereotype-related information is linearly decodable in middle layers but causally influential only near the output, and most sparse features are language- and category-specific.
Only the ILO metric survives controls for model size, family, and per-task variation when correlating with cross-lingual transfer, while other metrics are distorted by anisotropy.
Only one out of 22 recurring SAE features per model causally transfers across 23 language settings, revealing that feature recurrence overestimates cross-lingual mechanism transfer.
All three latent-selection methods steer language in two small multilingual LLMs; FreqSel wins only when given many more latents, and language control is redundant and non-orthogonal across methods.
ChronoLens uses feature-aligned crosscoders to show that historical language change has comparable magnitude across linguistic levels within a language, but divergent timing and direction across five parliamentary languages.
Language-specific sparse autoencoder features can be identified from monolingual data alone by filtering out features that also activate on random-token sequences, and steering with these features improves language control.
Fine-tuning an LLM to verbalize injected SAE decoder directions yields reference-agreeing explanations for held-out features, with adapter-based transfer across model families.
Qwen-Scope provides open-source sparse autoencoders for Qwen models that function as practical interfaces for steering, evaluating, data workflows, and optimizing large language models.
