IET Software

The goal of this study is to report the state-of-the-practice of DevSecOps, including the impact of DevOps on security, practitioners' understanding of DevSecOps, and the practices associated with DevSecOps as well as the challenges of implementing DevSecOps. We carried out a grey literature review on DevSecOps, and surveyed the practitioners of DevSecOps in industry. Three major software security risks are identified with DevOps, where the establishment of DevOps pipeline provides opportunities for security-related activities. Read the paper here.

The paper with the title of ``Fed-SC: One-Shot Federated Subspace Clustering over High-Dimensional Data'' proposes a one-shot federated subspace clustering scheme Fed-SC that can achieve remarkable clustering effectiveness on high-dimensional data while keeping communication cost low using only one round of communication for each local device. The paper further establishes theoretical guarantees on the clustering effectiveness of one-shot Fed-SC and exploits the benefits of statistical heterogeneity across distributed data. Extensive experiments on synthetic and real-world datasets demonstrate significant effectiveness gains of Fed-SC compared with both subspace clustering and one-shot federated clustering methods.

Service monitoring through anomaly detection and root cause analysis (RCA) is crucial for online microservice systems to provide stable and continued services. Microservice systems rely on telemetry data to perform service monitoring and RCA of service anomalies. In this paper, we propose a new RCA solution TrinityRCL that is able to localize the root causes of anomalies at multiple levels of granularity including application-level, service-level, host-level, and metric-level, with the unique capability of code-level localization by harnessing all three types of telemetry data to construct a causal graph representing the intricate, dynamic, and nondeterministic relationships among the various entities related to the anomalies.

ADHD is a neurobiological condition that often affects school children. A major symptom is short attention span, which may negatively influence their academic performance, specifically in those tasks that require concentration. In this work, we design and evaluate a novel gaze-based visual attentive interface for the purpose of extending ADHD children's attention span in performing reading tasks. The results show that these children performed better in the presence of any color scheme in comparison with using no color, with highlighting the most effective, followed by contrast and then sharpening/blurring.

Laid on the foundation of the Human-AI Interactive and Continuous Sensemaking framework published at ACM CHI 2021, this paper explores the effectiveness of regularizing CNN network with human-provided attention guidance on where in the image the network should look for answering clues. On two orthopedics radiographic fracture classification datasets, through extensive experiments we demonstrate that explicit human-guided attention indeed can direct correct network attention and consequently significantly improve classification performance.

This project, led by Swinburne University of Technology, aims to devise a novel Internet of Things (IoT) sensor sharing marketplace that permits IoT applications to discover, integrate, and pay for any IoT sensor data that is made available by other parties. It will devise highly-scalable sensor classification, query processing, and transactions solutions and incorporate them in a pair of novel blockchains that work in tandem to securely manage all the information and contracts needed by IoT applications. This grant is the third one in a row from the HilstLab, following one in 2019-2020 and another in 2020-2021, both from Department of Defence.

This paper investigates a novel theoretical problem of finding maximum disjoint paths with different colors (MDPDC). In MDPDC, transmission frequencies in a network are modeled as different colors on network nodes. The aim is to find a maximum number of color-constrained node-disjoint paths where nodes must share the same color within any disjoint path, and differ in color among different disjoint paths. The outcome of this research will greatly reduce network burden on big data transmission in order to achieve better network bandwidth and load balancing. You can find the paper here.

ACM CHI 2021
The article on "Human-AI Interactive and Continuous Sensemaking: A Case Study of Image Classification using Scribble Attention Maps" presents a conceptual framework for supporting effective human-AI interaction. The framework, referred to as HAICS, has been validated by an image classification application using deep CNNs as a browser-based tool that displays network attention maps to the human for explainability and collects human's feedback in the form of scribble annotations overlaid onto the maps. Experimental results using a real-world fracture dataset has shown significant improvement of AI’s classification accuracy after fine-tuning itself to incorporate human’s feedback.
