SGF: a crowdsourced large-scale event dataset

This paper presents a crowdsourced dataset of a large-scale event with more than 1000 measuring participants. The detailed dataset consists of various location data and network measurements of all national carrier collected during a four-day event. The concentrated samples for this short time period enable detailed analysis, e.g., by correlating movement patterns and experienced network conditions

Towards Automatic Classification of Common Therapy Errors for Diabetes Therapy Support

Today, one in eleven adults is suffering from diabetes mellitus. Diabetes mellitus is a disease where the body's own insulin control system fails. Incorrectly treated diabetes mellitus will lead to serious complications like strokes, blindness, and ultimately, death. Too high or too low blood glucose levels are dangerous, an insulin over-dose can even be lethal. Hence, the correct dosage of insulin from diabetes patients is the key parameter in therapy. Therefore, the patients get educated regularly by diabetes experts. These training sessions contain data review by the experts in order to identify errors in the patients' dosage behavior. However, this review is time consuming, since the error identification for a wrong dosage is nontrivial. In this paper we investigate the automatic classification of insulin dosage into three categories, representing correctly applied therapy and the most common therapy faults. We provide the experts with a pre-classified overview of the data, where the common errors are visually highlighted. This saves time in the consultation hour, enabling the expert to spend more time on investigating the patients individual problems. In our evaluation we compare multiple classification methods based on dynamic time warping against a convolutional neural network. The results show, that the convolutional neural network can achieve accuracy levels that are promising, although further improvements are required
