More specifically, we incorporate the textual description of incidents and structural information extracted from historical linked incidents to identify possible links among a large number of incidents. To show the effectiveness of our method, we apply our method to a real-world IcM system and find that our method outperforms other state-of-the-art methods.]]> Wed 06 Jul 2022 09:15:10 AEST ]]> How to mitigate the incident?

Characterizing and prioritizing incidents for large-scale online service systems https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:39861 incidental incidents. Our qualitative and quantitative analyses show that incidental incidents are significant in terms of both number and cost. Therefore, it is important to prioritize incidents by identifying incidental incidents in advance to optimize incident management efforts. In particular, we propose an approach, called DeepIP (Deep learning based Incident Prioritization), to prioritizing incidents based on a large amount of historical incident data. More specifically, we design an attention-based Convolutional Neural Network (CNN) to learn a prediction model to identify incidental incidents. We then prioritize all incidents by ranking the predicted probabilities of incidents being incidental. We evaluate the performance of DeepIP using real-world incident data. The experimental results show that DeepIP effectively prioritizes incidents by identifying incidental incidents and significantly outperforms all the compared approaches. For example, the AUC of DeepIP achieves 0.808, while that of the best compared approach is only 0.624 on average.]]> Wed 06 Jul 2022 08:36:19 AEST ]]> Automatic Discovery and Cleansing of Numerical Metamorphic Relations https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:49596 Tue 23 May 2023 12:45:20 AEST ]]> Learning to prioritize test programs for compiler testing https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:32674 learning to test, which learns the characteristics of bug-revealing test programs from previous test programs that triggered bugs. Based on the idea of learning to test, we propose LET, an approach to prioritizing test programs for compiler testing acceleration. LET consists of a learning process and a scheduling process. In the learning process, LET identifies a set of features of test programs, trains a capability model to predict the probability of a new test program for triggering compiler bugs and a time model to predict the execution time of a test program. In the scheduling process, LET prioritizes new test programs according to their bug-revealing probabilities in unit time, which is calculated based on the two trained models. Our extensive experiments show that LET significantly accelerates compiler testing. In particular, LET reduces more than 50% of the testing time in 24.64% of the cases, and reduces between 25% and 50% of the testing time in 36.23% of the cases.]]> Tue 10 Jul 2018 15:38:29 AEST ]]> History-guided configuration diversification for compiler test-program generation https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:45930 Tue 08 Nov 2022 10:00:09 AEDT ]]> Understanding and predicting incident mitigation time https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:51431 Tue 05 Sep 2023 17:47:45 AEST ]]> A survey of compiler testing https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:42112 Thu 18 Aug 2022 14:07:42 AEST ]]> Robust log-based anomaly detection on unstable log data https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:42098 Thu 18 Aug 2022 11:43:37 AEST ]]> Continuous incident triage for large-scale online service systems https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:43375 Thu 15 Sep 2022 15:53:31 AEST ]]> An empirical comparison of compiler testing techniques https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:27051 Sat 24 Mar 2018 07:25:23 AEDT ]]> APIRecX: Cross-Library API Recommendation via Pre-Trained Language Model https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:42850 Mon 05 Sep 2022 15:33:19 AEST ]]> Static duplicate bug-report identification for compilers https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:46583 Fri 25 Nov 2022 14:00:32 AEDT ]]> How long will it take to mitigate this incident for online service systems? https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:39739 Fri 17 Jun 2022 18:27:13 AEST ]]> LS-sampling: An effective local search based sampling approach for achieving high t-wise coverage https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:48883 Fri 14 Apr 2023 10:50:46 AEST ]]> On the Evaluation of Neural Code Summarization https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:47307 Fri 13 Jan 2023 10:59:48 AEDT ]]> Efficient Compiler Autotuning via Bayesian Optimization https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:40338 Fri 08 Jul 2022 10:19:33 AEST ]]>
