The importance of the evaluation of the transversal competences in engineering studies is explained in this chapter. Transversal competences are of great importance to enterprises that like to recruit students after their graduation. They look for trained professionals, thoroughly prepared not only to solve practical problems but also to be successfully integrated in a team work. Transversal competences are not directly related to the theoretical content of the curricula, and the assessment of the level of transversal competences developed through the university studies is not an easy task. A methodology for evaluating transversal skills during the Final Year Project (FYP) assessment is proposed. And a new modality of FYP to improve the acquisition of transversal skills is presented.
Purpose: The main objective of this study is to characterize the activation regions of three Deep Learning models using infrared images of the optic nerve of glaucoma patients.
Methods: We have retrospectively collected a sample of patients with primary and secondary open‐angle glaucoma and normal patients. The images in infrared were recorded with a spectral domain optical coherence tomography. Three previously trained models were used, VGG19, ResNet101 and the Shufflenet. Sensitivity, specificity, diagnostic accuracy in training and testing, and ROC area were calculated for all three models. The gradient‐weighted class activation map (GradCAM) was used to obtain the activation regions that highlight the most important components in the images for model prediction. The correlation coefficient between the glaucoma activation maps and between normal activation maps of the three models was calculated, and the location of the activation regions in the glaucoma and normal images was determined for each model.
Results: 639 eyes of 415 patients were collected, 432 glaucomatous and 207 normal. The accuracy of the models on the test set was 96.9% (VGG19), 95.3% (ResNet101), and 93.8% (Shufflenet). The activation maps of the ResNet101 and Shufflenet models obtained a high correlation in glaucoma (0.75) and normal (0.68) cases. For the three models, the region of interest was located mainly in the inferior temporal quadrant in 65.2% of the cases (VGG19), in 52.9% (Shufflenet) and in 54.1% (ResNet101).
Conclusions: In glaucoma eyes, the regions of interest assessed with the gradient‐weighted class activation maps of the three models analysed are located in more than half of the cases in the inferior temporal quadrant of the optic nerve.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
