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

ICML 2026poster

Sparse autoencoders (SAEs) have become a standard tool for mechanistic interpretability in autoregressive large language models (LLMs), enabling researchers to extract sparse, human-interpretable features and intervene on model behavior. Recently, as diffusion language models (DLMs) have become an i…

SASFT: Sparse Autoencoder-guided Supervised Finetuning to Mitigate Unexpected Code-Switching in LLMs

ICLR 2026poster

Large Language Models (LLMs) have impressive multilingual capabilities, but they suffer from unexpected code-switching, also known as language mixing, which involves switching to unexpected languages in the model response. This problem leads to poor readability and degrades the usability of model re…

CultureSynth: A Hierarchical Taxonomy-Guided and Retrieval-Augmented Framework for Cultural Question-Answer Synthesis

EMNLP 2025

Cultural competence, defined as the ability to understand and adapt to multicultural contexts, is increasingly vital for large language models (LLMs) in global environments. While several cultural benchmarks exist to assess LLMs’ cultural competence, current evaluations suffer from fragmented taxono

NOVA-63: Native Omni-lingual Versatile Assessments of 63 Disciplines

EMNLP 2025

The multilingual capabilities of large language models (LLMs) have attracted considerable attention over the past decade. Assessing the accuracy with which LLMs provide answers in multilingual contexts is essential for determining their level of multilingual proficiency. Nevertheless, existing multi

P-MMEval: A Parallel Multilingual Multitask Benchmark for Consistent Evaluation of LLMs

EMNLP 2025

Recent advancements in large language models (LLMs) showcase varied multilingual capabilities across tasks like translation, code generation, and reasoning. Previous assessments often limited their scope to fundamental natural language processing (NLP) or isolated capability-specific tasks. To allev

Unveiling Language-Specific Features in Large Language Models via Sparse Autoencoders

ACL 2025long

The mechanisms behind multilingual capabilities in Large Language Models (LLMs) have been examined using neuron-based or internal-activation-based methods. However, these methods often face challenges such as superposition and layer-wise activation variance, which limit their reliability. Sparse Aut…

AvatarGPT: All-in-One Framework for Motion Understanding Planning Generation and Beyond

CVPR 2024poster

Large Language Models(LLMs) have shown remarkable emergent abilities in unifying almost all (if not every) NLP tasks. In the human motion-related realm however researchers still develop siloed models for each task. Inspired by InstuctGPT[??] and the generalist concept behind Gato [??] we introduce A…

Attention Mechanism with Energy-Friendly Operations

ACL 2022findings

Attention mechanism has become the dominant module in natural language processing models. It is computationally intensive and depends on massive power-hungry multiplications. In this paper, we rethink variants of attention mechanism from the energy consumption aspects. After reaching the conclusion…

UniTE: Unified Translation Evaluation

ACL 2022long

Translation quality evaluation plays a crucial role in machine translation. According to the input format, it is mainly separated into three tasks, i.e., reference-only, source-only and source-reference-combined. Recent methods, despite their promising results, are specifically designed and optimize…
