Overfitting of neural nets under class imbalance: Analysis and improvements for segmentation

TL;DR: This study analyzes overfitting by examining how the distribution of logits alters in relation to how much the model overfits, and derives asymmetric modifications of existing loss functions and regularizers including a large margin loss, focal loss, adversarial training and mixup which specifically aim at reducing the shift observed when embedding unseen samples of the under-represented class.

Learning and combining image neighborhoods using random forests for neonatal brain disease classification.

TL;DR: It is shown that combining multiple distances related to the condition improves the overall characterization and classification of the three clinical groups compared to the use of single distances and classical unsupervised manifold learning.

Surgery versus conservative treatment for traumatic acute subdural haematoma: a prospective, multicentre, observational, comparative effectiveness study

Thomas A. van Essen, +254 more
- 01 May 2022 - 
TL;DR: Treatment for patients with acute subdural haematoma with similar characteristics differed depending on the treating centre, because of variation in the preferred approach, and a treatment strategy preferring an aggressive approach of acute surgical evacuation over initial conservative treatment was not associated with better functional outcome.
Journal ArticleDOI

A flexible graphical model for multi-modal parcellation of the cortex.

TL;DR: Quantitative and qualitative results on the Human Connectome Project database show that integrating multi‐modal information yields a stronger agreement with well established atlases and more robust connectivity networks that provide a better representation of the population.
