False arrhythmia alarms pose a major threat to the quality of care in today’s ICU. Thus, the PhysioNet/Computing in Cardiology Challenge 2015 aimed at reducing false alarms by exploiting multimodal cardiac signals recorded by a patient monitor. False alarms for asystole, extreme bradycardia, extreme tachycardia, ventricular flutter/fibrillation as well as ventricular tachycardia were to be redu...

BACKGROUND Intensive care units (ICUs) are complex work environments where false alarms occur more frequently than on non-critical care units. The Joint Commission National Patient Safety Goal .06.01.01 targeted improving the safety of clinical alarm systems and required health care facilities to establish alarm systems safety as a hospital priority by July 2014. An important initial step towar...

Within animal groups, individuals can learn of a predator's approach by attending to the behaviour of others. This use of social information increases an individual's perceptual range, but can also lead to the propagation of false alarms. Error copying is especially likely in species that signal collectively, because the coordination required for collective displays relies heavily on social inf...

A corpus of 291 small C-program test cases was developed to evaluate static and dynamic analysis tools designed to detect buffer overflows. The corpus was designed and labeled using a new, comprehensive buffer overflow taxonomy. It provides a benchmark to measure detection, false alarm, and confusion rates of tools, and also suggests areas for tool enhancement. Experiments with five tools demon...

Eurocontrol has introduced a Tactical Controller Tool (TCT), for use by Tactical Air Traffic Controllers (ATCs) who require trajectory conflict information over the next 5 to 8 minutes to help them detect conflicts in their sector. Simulation trials indicate that the safety benefits of TCT may be limited because of large numbers of False Alarms. There is a need to tune the system to identify th...

The overwhelming number of alarms generated by rule-based network intrusion detection systems makes the task of network security operators ineffective. Preliminary results on an approach called EXOLAP shows that false positives alarms can be avoided by detecting changes on the stream of alarms using a data cube and median polish procedure. A data cube aggregates alarms by hierarchical time fram...
