Task-Agnostic Federated Continual Learning via Replay-Free Gradient Projection

Seohyeon Cha, Huancheng Chen, Haris Vikalo

Federated continual learning (FCL) enables collaborative model training across distributed clients on sequentially arriving tasks without revisiting past data. However, existing ap…

FedRot-LoRA: Mitigating Rotational Misalignment in Federated LoRA

Haoran Zhang, Dongjun Kim, Seohyeon Cha +1

Federated LoRA provides a communication-efficient mechanism for fine-tuning large language models on decentralized data. In practice, however, a discrepancy between the factor-wise…

CoreQ: Learning-Free Mismatch Correction and Successive Rounding for Quantization

Seohyeon Cha, Huancheng Chen, Dongjun Kim +4

Post-training quantization (PTQ) enables efficient deployment of large language models by mapping pretrained weights to low-bit formats without retraining, typically using a small…

Online Learning for Multi-Layer Hierarchical Inference under Partial and Policy-Dependent Feedback

Haoran Zhang, Seohyeon Cha, Hasan Burhan Beytur +3

Hierarchical inference systems route tasks across multiple computational layers, where each node may either finalize a prediction locally or offload the task to a node in the next…

Batching-Aware Joint Model Onloading and Offloading for Hierarchical Multi-Task Inference

Seohyeon Cha, Kevin Chan, Gustavo de Veciana +1

The growing demand for intelligent services on resource-constrained edge devices has spurred the development of collaborative inference systems that distribute workloads across end…
