Effects of Image Degradation on Deep Neural Network Classification of Scaphoid Fracture Radiographs: Comparison Study of Different Noise Types

Effects of Image Degradation on Deep Neural Network Classification of Scaphoid Fracture Radiographs: Comparison Study of Different Noise Types

The study protocol was approved by the institutional review board of Chang Gung Memorial Hospital (202202256 B0). As previously described in our earlier work [10], the scaphoid fracture classification model was built using an Efficient Net B1 [13] backbone and 240×240-pixel red, green, and blue (RGB) images with a classification threshold of 0.5. In a study by Yoon et al [10], the model was originally trained and validated using 3991 scaphoid fracture radiographs and 5542 normal scaphoid radiographs.

Mild Cognitive Impairment Detection System Based on Unstructured Spontaneous Speech: Longitudinal Dual-Modal Framework

Mild Cognitive Impairment Detection System Based on Unstructured Spontaneous Speech: Longitudinal Dual-Modal Framework

In our previous work proposed by Chang et al [11], the author first extracted traditional acoustic feature sets, extended Geneva Minimalistic Acoustic Parameter Set [12], from AM audio files collected across multiple visits. The author then used Tab Net [13] to learn the cognitive information embedded within these feature sets. To further enhance the model, an aging alignment loss was applied, encouraging cognitive representations in the latent space to be closer to each other.

Impact of Age on Hospital Outcomes Following Minimally Invasive Posterior Lumbar Interbody Fusion: Retrospective Analysis of the Nationwide Inpatient Sample Database from 2016 to 2020

Impact of Age on Hospital Outcomes Following Minimally Invasive Posterior Lumbar Interbody Fusion: Retrospective Analysis of the Nationwide Inpatient Sample Database from 2016 to 2020

The protocol for this study was submitted for review to the Institutional Review Board of Chang Gung Medical Foundation (202301168 B0), which granted an exemption from formal Institutional Review Board oversight. This study complies with the terms of the Nationwide Inpatient Sample (NIS) data-use agreement. The data used in this study were obtained through the Online Health Care Cost and Utilization Project (HCUP) Central Distributor.
