(Empirical) Bayes Approaches to Parallel Trends

no code implementations18 Apr 2024 Soonwoo Kwon, Jonathan Roth

We consider Bayes and Empirical Bayes (EB) approaches for dealing with violations of parallel trends.

Testing Mechanisms

no code implementations17 Apr 2024 Soonwoo Kwon, Jonathan Roth

Economists are often interested in the mechanisms by which a particular treatment affects an outcome.

Denoising Task Difficulty-based Curriculum for Training Diffusion Models

no code implementations15 Mar 2024 Jin-Young Kim, Hyojun Go, Soonwoo Kwon, Hyun-Gyoon Kim

By organizing timesteps or noise levels into clusters and training models with descending orders of difficulty, we facilitate an order-aware training regime, progressing from easier to harder denoising tasks, thereby deviating from the conventional approach of training diffusion models simultaneously across all timesteps.

Optimal Shrinkage Estimation of Fixed Effects in Linear Panel Data Models

no code implementations24 Aug 2023 Soonwoo Kwon

Shrinkage methods are frequently used to estimate fixed effects to reduce the noisiness of the least squares estimators.

Addressing Selection Bias in Computerized Adaptive Testing: A User-Wise Aggregate Influence Function Approach

1 code implementation23 Aug 2023 Soonwoo Kwon, Sojung Kim, SeungHyun Lee, Jin-Young Kim, Suyeong An, Kyuseok Kim

Indeed, when naively training the diagnostic model using CAT response data, we observe that item profiles deviate significantly from the ground-truth.

ScoreCL: Augmentation-Adaptive Contrastive Learning via Score-Matching Function

no code implementations7 Jun 2023 Jin-Young Kim, Soonwoo Kwon, Hyojun Go, Yunsung Lee, Seungtaek Choi

Self-supervised contrastive learning (CL) has achieved state-of-the-art performance in representation learning by minimizing the distance between positive pairs while maximizing that of negative ones.

Towards an Efficient ML System: Unveiling a Trade-off between Task Accuracy and Engineering Efficiency in a Large-scale Car Sharing Platform

1 code implementation10 Oct 2022 Kyung Ho Park, Hyunhee Chung, Soonwoo Kwon

Under various image recognition tasks in the real world car-sharing platform, our study illustrates how we established the proposed system and lessons learned from this journey as follows.

Bias-Aware Inference in Regularized Regression Models

no code implementations29 Dec 2020 Timothy B. Armstrong, Michal Kolesár, Soonwoo Kwon

We consider inference on a scalar regression coefficient under a constraint on the magnitude of the control coefficients.
