TALAS: Teacher-Anchored Layer Alignment with Adaptive Sharpness-Aware Minimization for Embedding Distillation

Quoc Phong Dao, Hoang Son Nguyen, Pham Khanh Chi +4

Knowledge Distillation (KD) has established itself as a pivotal technique for compressing large pre-trained language models. However, existing methods that force a student to stric…

TokenRatio: Principled Token-Level Preference Optimization via Ratio Matching

Truong Nguyen, Tien-Phat Nguyen, Linh Ngo Van +3

Direct Preference Optimization (DPO) is a widely used RL-free method for aligning language models from pairwise preferences, but it models preferences over full sequences even thou…

LLM-XTM: Enhancing Cross-Lingual Topic Models with Large Language Models

Minh Chu Xuan, Tien-Phat Nguyen, Linh Ngo Van +3

Cross-lingual topic modeling aims to discover shared semantic structures across languages, yet existing models depend on sparse bilingual resources and often yield incoherent or we…

MemORAI: Memory Organization and Retrieval via Adaptive Graph Intelligence for LLM Conversational Agents

Hung Pham Van, Nguyen Manh Hieu, Khang Pham Tran Tuan +4

Large Language Models (LLMs) lack persistent memory for long-term personalized conversations. Existing graph-based memory systems suffer from information dilution, absent provenanc…

MTA: Multi-Granular Trajectory Alignment for Large Language Model Distillation

Pham Khanh Chi, Quoc Phong Dao, Thuat Nguyen +3

Knowledge distillation is a key technique for compressing large language models (LLMs), but most existing methods align representations at fixed layers or token-level outputs, igno…

SRA: Span Representation Alignment for Large Language Model Distillation

Quoc Phong Dao, Hoang Son Nguyen, Pham Khanh Chi +4

Cross-Tokenizer Knowledge Distillation (CTKD) enables knowledge transfer between a large language model and a smaller student, even when they employ different tokenizers. While exi…
