However, the sheer volume of CXR images, especially during pandemics, combined with the complexity of subtle abnormalities, poses significant challenges for manual analysis. Lung segmentation plays a pivotal role in artificial intelligence-driven CXR analysis by isolating lung fields, which facilitates the detection of disease-affected regions. Recent advances in deep learning, particularly with attention mechanisms, have improved segmentation accuracy, but the performance of these models heavily depends on the selection of appropriate hyperparameters. This study investigates the impact of key hyperparameters—learning rate and number of epochs—on the performance of the dual-attention network (DANet) in lung segmentation tasks. DANet was tested on a CXR dataset from Qatar University and evaluated under four different hyperparameter configurations: 20 epochs with a learning rate of 0.001, 10 epochs with a learning rate of 0.001, 10 epochs with a learning rate of 0.0001 and 20 epochs with a learning rate of 0.0001. The model's performance was assessed using two widely recognised segmentation metrics: the Dice coefficient and Intersection over Union (IoU). The results indicated that higher learning rates and greater numbers of epochs lead to improved segmentation performance. Specifically, the DANet model achieved a Dice coefficient of 97.29 % and an IoU value of 94.74 %, demonstrating its effectiveness compared to other models. These findings highlight the importance of hyperparameter tuning in achieving high segmentation accuracy and demonstrate the potential of the DANet model to improve diagnostic workflows for CXR analysis.</div></div>","PeriodicalId":73399,"journal":{"name":"Intelligence-based medicine","volume":"11 ","pages":"Article 100221"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143480059","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Small deficits in repetitive fast movements, such as slightly slowed finger-tapping or mildly irregular rhythm of stepping, are often an early sign of a neurological disorder. Accessible tools that precisely measure the individual components of fast movements would thus enhance disease detection, monitoring and research. Deep learning-based computer vision methods applied to digital video-recordings hold promise but current state-of-the-art tools, including DeepLabCut (DLC) and other advanced models, fail to accurately track the fastest range of human movements, primarily due to image blur. To solve this, we developed a new end-to-end, Rapid-Motion-Track (RMT) computer vision tool. This study aimed to evaluate the accuracy of RMT compared to DLC and other advanced computer vision tools. 220 finger-tapping tests were performed at frequencies between 0.5Hz and 6Hz and recorded simultaneously with a standard 30 frames/sec 2D laptop camera and a high-speed 250 frames/sec 3D motion tracking system (ground-truth). Bland-Altman plots and paired Welch's <em>t</em>-test were used to quantify the validity of movement features extracted by computer vision methods with the ground-truth. The movement features extracted by RMT (e.g. frequency, speed, variance) exhibited high concurrent validity across all tapping-frequencies. RMT outperformed other computer vision methods for very fast movements &gt;4Hz. RMT also robustly tracked other fast motions including sit-to-stand, head-turning, foot-tapping, and leg agility.
