Don't Just Blame Over-parametrization for Over-confidence: Theoretical Analysis of Calibration in Binary Classification [article]

Yu Bai, Song Mei, Huan Wang, Caiming Xiong
2021 arXiv   pre-print
In this paper, we show theoretically that over-parametrization is not the only reason for over-confidence.  ...  Overall, our theory provides a precise characterization of calibration in realizable binary classification, which we verify on simulations and real data experiments.  ...  Acknowledgment We thank Yuxin Chen for the insightful discussions on the system of nonlinear equations.  ...

Exploring the role of Entrustable Professional Activities in assessing final year medical students [article]

Katharine Rankin, University Of Edinburgh, Alan Jaap, Helen Cameron
The concept of Entrustable Professional Activities (EPAs) has been introduced in postgraduate medical education to try to bridge the gap between theoretical aspects of competency-based education and real-life  ...  Using Kane's framework, I present a validity argument for the use of EPAs in this context using mixed methods underpinned by the ontological framework of Critical Realism and an interpretivist epistemology  ...  His over confidence may then be mitigated by a few months of working in the reality of the clinical domain.  ...

Efficiency and effectiveness : exploring the goals of technology-diverse universal electrification strategies

Vikas Menghwani
Key outcomes of this work include novel methodologies for incorporating non-technological factors into electrification modeling.  ...  Modeling results show that (for Tanzania) uncertainty around grid arrival risks large scale misallocation of potential off-grid investments and may leave a large segment of population without electricity  ...  This is a binary measure of electricity access, as it just does a headcount of households with an electricity connection.  ...
