Model-based Large Language Model Customization as Service

EMNLP 2025

Prominent Large Language Model (LLM) services from providers like OpenAI and Google excel at general tasks but often underperform on domain-specific applications. Current customization services for these LLMs typically require users to upload data for fine-tuning, posing significant privacy risks. W

Federated Transformer: Multi-Party Vertical Federated Learning on Practical Fuzzily Linked Data

NeurIPS 2024poster

Federated Learning (FL) is an evolving paradigm that enables multiple parties to collaboratively train models without sharing raw data. Among its variants, Vertical Federated Learning (VFL) is particularly relevant in real-world, cross-organizational collaborations, where distinct features of a shar…

VertiBench: Advancing Feature Distribution Diversity in Vertical Federated Learning Benchmarks

ICLR 2024poster

Vertical Federated Learning (VFL) is a crucial paradigm for training machine learning models on feature-partitioned, distributed data. However, due to privacy restrictions, few public real-world VFL datasets exist for algorithm evaluation, and these represent a limited array of feature distributions…
