Item Developing a Resource-Constraint EdgeAI model for Surface Defect Detection(2023) Mih, Atah Nuh; Cao, Hung; Kawnine, Asfia; Wachowicz, MonicaResource constraints have restricted several EdgeAI applications to machine learning inference approaches, where models are trained on the cloud and deployed to the edge device. This poses challenges such as bandwidth, latency, and privacy associated with storing data off-site for model building. Training on the edge device can overcome these challenges by eliminating the need to transfer data to another device for storage and model development. On-device training also provides robustness to data variations as models can be retrained on newly acquired data to improve performance. We therefore propose a lightweight EdgeAI architecture modified from Xception, for on-device training in a resource-constraint edge environment. We evaluate our model on a PCB defect detection task and compare its performance against existing lightweight models - MobileNetV2, EfficientNetV2B0, and MobileViT-XXS. The results of our experiment show that our model has a remarkable performance with a test accuracy of 73.45% without pre-training. This is comparable to the test accuracy of non-pre-trained MobileViT-XXS (75.40%) and much better than other non-pre-trained models (MobileNetV2 - 50.05%, EfficientNetV2B0 - 54.30%). The test accuracy of our model without pre-training is comparable to pre-trained MobileNetV2 model - 75.45% and better than pre-trained EfficientNetV2B0 model - 58.10%. In terms of memory efficiency, our model performs better than EfficientNetV2B0 and MobileViT-XXS. We find that the resource efficiency of machine learning models does not solely depend on the number of parameters but also depends on architectural considerations. Our method can be applied to other resource-constraint applications while maintaining significant performance.Item Correlates of new graduate nurses’ experiences of workplace mistreatment(Lippincott, 2013) Read, Emily; Laschinger, Heather K.Objective: This study explores antecedents and consequences of new graduate nurses’ experiences of workplace mistreatment. Background: New graduate nurses’ experiences of workplace mistreatment negatively influence organizational and personal health outcomes. Three types of workplace mistreatment are bullying, co-worker incivility, and supervisor incivility. It is unclear whether the relationships between precipitating factors and outcomes are similar when new graduate nurses experience these different types of workplace mistreatment. Methods: We surveyed 342 new graduate nurses in Ontario to examine the exploratory model related to each negative workplace behavior experience. Results: Community had a stronger correlation to co-worker incivility (-.58) than supervisor incivility (-.32) and bullying (-.44). Structural empowerment was more related to bullying (-.34) and co-worker incivility (-.30) than supervisor incivility (-.22). Bullying had stronger correlations to all outcome variables. Job satisfaction, emotional exhaustion, and personal health outcomes were all negatively related to workplace mistreatment. Conclusions: New graduate nurses’ experiences of three types of workplace mistreatment have similar relationships to precipitating factors and outcomes with stronger correlations to bullying than incivility.
