One computer security mechanism used currently is the Intrusion Detection System (IDS). Off-line IDSs search audit trail registries looking for user activities that match patterns of events known as attacks. Because such search is NP-complete, heuristic methods will need to be employed as databases of events and attacks grow. Genetic Algorithms (GAs) have been widely used as heuristic search me...

The growing usage of digital microphones has generated an increased interest in the topic Acoustic Anomaly Detection (AAD). Indeed, there are several real-world AAD application domains, including working machines and in-vehicle intelligence (the main target this research project). This paper introduces three deep AutoEncoders (AE) for unsupervised tasks, namely a Dense AE, Convolutional Neural ...

BACKGROUND Marketing authorization holders (MAHs) are obligated to report adverse events (AEs) within 15 days (some cases 30 days) to the Pharmaceuticals and Medical Devices Agency (PMDA) of Japan. METHODS To analyze the timeliness of AE reporting to the PMDA, 6610 reports for five categories of cardiovascular devices were retrieved. Two durations were calculated: (1) time from the date the A...
