Inference with non-differentiable surrogate loss in a general high-dimensional classification framework

no code implementations20 May 2024 Muxuan Liang, Yang Ning, Maureen A Smith, Ying-Qi Zhao

In this work, we propose a kernel-smoothed decorrelated score to construct hypothesis testing and interval estimations for the linear decision rule estimated using a piece-wise linear surrogate loss, which has a discontinuous gradient and non-regular Hessian.

MicroSegNet: A Deep Learning Approach for Prostate Segmentation on Micro-Ultrasound Images

1 code implementation31 May 2023 Hongxu Jiang, Muhammad Imran, Preethika Muralidharan, Anjali Patel, Jake Pensa, Muxuan Liang, Tarik Benidir, Joseph R. Grajo, Jason P. Joseph, Russell Terry, John Michael DiBianco, Li-Ming Su, Yuyin Zhou, Wayne G. Brisbane, Wei Shao

During the training process, MicroSegNet focuses more on regions that are hard to segment (hard regions), characterized by discrepancies between expert and non-expert annotations.

Robust and flexible learning of a high-dimensional classification rule using auxiliary outcomes

no code implementations11 Nov 2020 Muxuan Liang, Jaeyoung Park, Qing Lu, Xiang Zhong

The proposed method includes an MTL step using all outcomes to gain efficiency, and a subsequent calibration step using only the outcome of interest to correct both types of biases.
