Enhancing LLMs via High-Knowledge Data Selection

AAAI 2025technical

The performance of Large Language Models (LLMs) is intrinsically linked to the quality of its training data. Although several studies have proposed methods for high-quality data selection, they do not consider the importance of knowledge richness in text corpora. In this paper, we propose a novel an…

FIRE: Flexible Integration of Data Quality Ratings for Effective Pretraining

EMNLP 2025

Selecting high-quality data can improve the pretraining efficiency of large language models (LLMs). Existing methods generally rely on heuristic techniques or single quality signals, limiting their ability to evaluate data quality comprehensively. In this work, we propose FIRE, a flexible and scalab

FRAME: Boosting LLMs with A Four-Quadrant Multi-Stage Pretraining Strategy

ACL 2025finding

Large language models (LLMs) have significantly advanced human language understanding and generation, with pretraining data quality and organization being crucial to their performance. Multi-stage pretraining is a promising approach, but existing methods often lack quantitative criteria for data par…

LLMs Know What They Need: Leveraging a Missing Information Guided Framework to Empower Retrieval-Augmented Generation

COLING 2025main

Retrieval-Augmented Generation (RAG) demonstrates great value in alleviating outdated knowledge or hallucination by supplying LLMs with updated and relevant knowledge. However, RAG still faces several challenges in tackling complex multi-hop queries, which require LLMs to perform accurate reasoning…

Preference Curriculum: LLMs Should Always Be Pretrained on Their Preferred Data

ACL 2025finding

Large language models (LLMs) generally utilize a consistent data distribution throughout the pretraining process. However, as the model’s capability improves, it is intuitive that its data preferences dynamically change, indicating the need for pretraining with different data at various training sta…

D-CPT Law: Domain-specific Continual Pre-Training Scaling Law for Large Language Models

NeurIPS 2024poster

Continual Pre-Training (CPT) on Large Language Models (LLMs) has been widely used to expand the model’s fundamental understanding of specific downstream domains (e.g., math and code). For the CPT on domain-specific LLMs, one important question is how to choose the optimal mixture ratio between the g…

PositionID: LLMs can Control Lengths, Copy and Paste with Explicit Positional Awareness

EMNLP 2024finding

Large Language Models (LLMs) demonstrate impressive capabilities across various domains, including role-playing, creative writing, mathematical reasoning, and coding. Despite these advancements, LLMs still encounter challenges with length control, frequently failing to adhere to specific length cons…
