Airlines operate tight schedules to maximise resource utilisation. However, the lack of sufficient buffers often result in the domino effect, where a delay of a single flight can delay many other dependent flights. Due to the complexity of air transportation systems the task of identifying the cause of a delay is not trivial. In this paper, we propose a framework for automatic detection of root-causes of delays and their propagation effects using airline historical data. The framework is composed of the following: 1) delay propagation model to create connection network, 2) delay network algorithm to find delay networks, and 3) community detection algorithm to identify root-causes and impact of disruptions. We test our framework on historical data of an airline, and show that the airline under study is prone to delay propagation through passenger connections. Additionally, majority of their delays are related to airport capacity, resource allocation, and passengers, and mainly originate from the hub. -Short bio: Dr Vaggelis Giannikas is an Associate Professor at the School of Management, University of Bath where he also directs the engineering management teaching portfolio.

A key challenge regarding trust in AI - also considered important by regulators as part of transparency for some AI applications - is to understand why “black boxes” may be making specific predictions. As a result, explainable AI (XAI) has been a growing topic of research. In this talk, I will discuss some potential drawbacks XAI may have - including the potential to erode safety in practice - and also present some work that takes into account behavioural aspects researchers and practitioners may need to consider when developing XAI. -### Speaker bio +#### Biography Theos Evgeniou is a professor of Decision Sciences and Technology Management at INSEAD and director of the INSEAD Executive Education program on Transforming your Business with AI.

Malicious applications can obtain access to such data and leak them to third parties with potentially grave consequences (i.e., theft, blackmail, etc.). Therefore, the study of malware, with the goal of identifying such malicious applications, has attracted significant research interest in recent years, especially focusing on Android applications. Malware research based on a combination of static and dynamic approaches has been shown to be effective in identifying a range of typical malware types like example keyloggers and ransomware. Moreover, it has been shown that applications that are not malware in the traditional sense, e.g. social networking applications or even over-privileged system applications, might leak significant amounts of data without user consent or notification. Therefore, this talk will provide an overview of trends in research regarding static and dynamic analysis for Android applications with the goal of identifying such malicious or information-leaking behaviors. We will discuss different approaches based on taint analysis, system call analysis, provenance tracking, network traffic analysis and more. The talk will also cover the extended Berkeley Packet Filter (eBPF) and how it can be useful for tracing and dynamic analysis. -Short bio: +#### Biography Simon Althaus is a Research Associate at the Telecooperation Lab at Technical University of Darmstadt.
