Overlap and busy members sitting on the audit committee

This paper investigates the impact of the presence of “over-boarded” directors on the audit committee on earnings management in Europe. Our study is based on a sample of 1420 firms from 15 European countries for the period 2006-2014. For the full sample, we find that the presence of “overlap” directors decreases earnings management, but the presence of “over-boarded” directors (i.e...

Semi-automatic training of an object recognition system in scene camera data using gaze tracking and accelerometers

Object detection and recognition algorithms usually require large, annotated training sets. The creation of such datasets requires expensive manual annotation. Eye tracking can help in the annotation procedure. Humans use vision constantly to explore the environment and plan motor actions, such as grasping an object. In this paper we investigate the possibility to semi-automatically...

Training deep convolutional neural networks with active learning for exudate classification in eye fundus images

Training deep convolutional neural network for classification in medical tasks is often difficult due to the lack of annotated data sam-ples. Deep convolutional networks (CNN) has been successfully used as an automatic detection tool to support the grading of diabetic retinopa-thy and macular edema. Nevertheless, the manual annotation of exu-dates in eye fundus images used to classify...

TUCUXI – an intelligent system for personalized medicine: : from individualization of treatments to research databases and back

Therapeutic Drug Monitoring (TDM) is a key concept in precision medicine. The goal of TDM is to avoid therapeutic failure or toxic effects of a drug due to insufficient or excessive circulating concen-tration exposure related to between-patient variability in the drug’s disposition. We present TUCUXI – an intelligent system for TDM. By making use of embedded mathematical models, the...
