OPUS: Towards Efficient and Principled Data Selection in Large Language Model Pre-training in Every Iteration

ICML 2026oral

As high-quality public text approaches exhaustion, a phenomenon known as the Data Wall—LLM pre-training is shifting from more tokens to better tokens. However, existing methods either rely on heuristic static filters that ignore training dynamics, or use dynamic yet optimizer-agnostic criteria based…

Rethinking LLM Evaluation: Can We Evaluate LLMs with 200× Less Data?

ICLR 2026poster

As the demand for comprehensive evaluations of diverse model capabilities steadily increases, benchmark suites have correspondingly grown significantly in scale. Despite notable advances in redundancy reduction and subset-level performance prediction, a systematic framework that effectively integrat…

DataMan: Data Manager for Pre-training Large Language Models

ICLR 2025poster

The performance emergence of large language models (LLMs) driven by data scaling laws makes the selection of pre-training data increasingly important. However, existing methods rely on limited heuristics and human intuition, lacking comprehensive and clear guidelines. To address this, we are inspir…

InjectTST: Injecting Global Information into Independent Channels for Long Time Series Forecasting

ICASSP 2025accepted

Transformer has become one of the most popular architectures for multivariate time series (MTS) forecasting. However, existing Transformer-based methods still lack consideration of cross-time-and-channel dependency modeling, which is important to MTS forecasting. In addition, existing methods either…

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

SuperGPQA: Scaling LLM Evaluation across 285 Graduate Disciplines

NeurIPS 2025poster

Large language models (LLMs) have demonstrated remarkable proficiency in mainstream academic disciplines such as mathematics, physics, and computer science. However, human knowledge encompasses over 200 specialized disciplines, far exceeding the scope of existing benchmarks. The capabilities of LLMs…

Fantastic Expressions and Where to Find Them: Chinese Simile Generation with Multiple Constraints

ACL 2023long

Similes occur in the creative context of describing a concept (i.e., tenor) by making a literally false yet figuratively meaningful comparison to another (i.e., vehicle). Previous efforts form simile generation as a context-free generation task, focusing on simile-style transfer or writing a simile…

Tailor: A Soft-Prompt-Based Approach to Attribute-Based Controlled Text Generation

ACL 2023long

Attribute-based Controlled Text Generation (CTG) refers to generating sentences that satisfy desirable attributes (e.g., emotions and topics). Existing work usually utilize fine-tuning or resort to extra attribute classifiers, yet suffer from increases in storage and inference time. To address these…

GCPG: A General Framework for Controllable Paraphrase Generation

ACL 2022findings

Controllable paraphrase generation (CPG) incorporates various external conditions to obtain desirable paraphrases. However, existing works only highlight a special condition under two indispensable aspects of CPG (i.e., lexically and syntactically CPG) individually, lacking a unified circumstance to…

POS-Constrained Parallel Decoding for Non-autoregressive Generation

ACL 2021long

The multimodality problem has become a major challenge of existing non-autoregressive generation (NAG) systems. A common solution often resorts to sequence-level knowledge distillation by rebuilding the training dataset through autoregressive generation (hereinafter known as “teacher AG”). The succe…
