Restricted access - publisher's policyIn this study, we train and compare three types of machine learning algorithms for Survival Analysis: Random Survival Forest, DeepSurv and DeepHit, using the SEER database to model cutaneous malignant melanoma. Additionally, ... -
Chapter 1.6: Early warning signals of Earth system tipping points
(University of Exeter, 2023)
Part of book or chapter of book
Open AccessThis chapter focuses on the methods used to predict the movement of parts of the Earth system towards tipping points. It begins by introducing the theory of critical slowing down (CSD), a general phenomenon of slowing ... -
Ionospheric scintillation models: An inter-comparison study using GNSS data
(IntechOpen, 2023-06-21)
Part of book or chapter of book
Open AccessExisting climatological ionosphere models, for example, GISM, SCIONAV, WBMOD, and STIPEE, have known limitations that prevent their wide use. In the framework of ESA study “Radio Climatology Models of the Ionosphere: Status ... -
Contrastive and attention-based multiple instance learning for the prediction of sentinel lymph node status from histopathologies of primary melanoma tumours
(Springer, 2022-09-30)
Part of book or chapter of book
Open AccessSentinel lymph node status is a crucial prognosis factor for melanomas; nonetheless, the invasive surgery required to obtain it always puts the patient at risk. In this study, we develop a Deep Learning-based approach to ... -
Design of minimum nonlinear distortion reconfigurable antennas for next-generation communication systems
