Towards Unbiased Evaluation of Detecting Unanswerable Questions in EHRSQL

no code implementations29 Apr 2024 Yongjin Yang, Sihyeon Kim, Sangmook Kim, Gyubok Lee, Se-Young Yun, Edward Choi

Incorporating unanswerable questions into EHR QA systems is crucial for testing the trustworthiness of a system, as providing non-existent responses can mislead doctors in their diagnoses.

FedSOL: Stabilized Orthogonal Learning with Proximal Restrictions in Federated Learning

no code implementations24 Aug 2023 Gihun Lee, Minchan Jeong, Sangmook Kim, Jaehoon Oh, Se-Young Yun

FedSOL is designed to identify gradients of local objectives that are inherently orthogonal to directions affecting the proximal objective.

Re-thinking Federated Active Learning based on Inter-class Diversity

1 code implementation CVPR 2023 Sangmook Kim, Sangmin Bae, Hwanjun Song, Se-Young Yun

In this work, we first demonstrate that the superiority of two selector models depends on the global and local inter-class diversity.

FedRN: Exploiting k-Reliable Neighbors Towards Robust Federated Learning

1 code implementation3 May 2022 Sangmook Kim, Wonyoung Shin, Soohyuk Jang, Hwanjun Song, Se-Young Yun

Robustness is becoming another important challenge of federated learning in that the data collection process in each client is naturally accompanied by noisy labels.

FedBABU: Toward Enhanced Representation for Federated Image Classification

1 code implementation ICLR 2022 Jaehoon Oh, Sangmook Kim, Se-Young Yun

Based on this observation, we propose a novel federated learning algorithm, coined FedBABU, which only updates the body of the model during federated training (i. e., the head is randomly initialized and never updated), and the head is fine-tuned for personalization during the evaluation process.
