FAIRification of MLC data

no code implementations23 Nov 2022 Ana Kostovska, Jasmin Bogatinovski, Andrej Treven, Sašo Džeroski, Dragi Kocev, Panče Panov

The multi-label classification (MLC) task has increasingly been receiving interest from the machine learning (ML) community, as evidenced by the growing number of papers and methods that appear in the literature.

Leveraging Log Instructions in Log-based Anomaly Detection

1 code implementation7 Jul 2022 Jasmin Bogatinovski, Gjorgji Madjarov, Sasho Nedelkoski, Jorge Cardoso, Odej Kao

Artificial Intelligence for IT Operations (AIOps) describes the process of maintaining and operating large IT systems using diverse AI-enabled methods and tools for, e. g., anomaly detection and root cause analysis, to support the remediation, optimization, and automatic initiation of self-stabilizing IT activities.

Failure Identification from Unstable Log Data using Deep Learning

1 code implementation6 Apr 2022 Jasmin Bogatinovski, Sasho Nedelkoski, Li Wu, Jorge Cardoso, Odej Kao

Our experimental results demonstrate that the learned subprocesses representations reduce the instability in the input, allowing CLog to outperform the baselines on the failure identification subproblems - 1) failure detection by 9-24% on F1 score and 2) failure type identification by 7% on the macro averaged F1 score.

Data-Driven Approach for Log Instruction Quality Assessment

1 code implementation6 Apr 2022 Jasmin Bogatinovski, Sasho Nedelkoski, Alexander Acker, Jorge Cardoso, Odej Kao

We start with an in-depth analysis of quality log instruction properties in nine software systems and identify two quality properties: 1) correct log level assignment assessing the correctness of the log level, and 2) sufficient linguistic structure assessing the minimal richness of the static text necessary for verbose event description.

Less is more: Selecting the right benchmarking set of data for time series classification

no code implementations29 Sep 2021 Tome Eftimov, Gašper Petelin, Gjorgjina Cenikj, Ana Kostovska, Gordana Ispirova, Peter Korošec, Jasmin Bogatinovski

By observing discrepancy between the empirical results of the bootstrap evaluation and recently adapted practices in TSC literature when introducing novel methods we warn on the potentially harmful effects of tuning the methods on certain parts of the landscape (unless this is an explicit and desired goal of the study).

Robust and Transferable Anomaly Detection in Log Data using Pre-Trained Language Models

no code implementations23 Feb 2021 Harold Ott, Jasmin Bogatinovski, Alexander Acker, Sasho Nedelkoski, Odej Kao

To that end, we utilize pre-trained general-purpose language models to preserve the semantics of log messages and map them into log vector embeddings.

Comprehensive Comparative Study of Multi-Label Classification Methods

no code implementations14 Feb 2021 Jasmin Bogatinovski, Ljupčo Todorovski, Sašo Džeroski, Dragi Kocev

Several studies provide reviews of methods and datasets for MLC and a few provide empirical comparisons of MLC methods.

Artificial Intelligence for IT Operations (AIOPS) Workshop White Paper

no code implementations15 Jan 2021 Jasmin Bogatinovski, Sasho Nedelkoski, Alexander Acker, Florian Schmidt, Thorsten Wittkopp, Soeren Becker, Jorge Cardoso, Odej Kao

Finally, all this will result in faster adoption of AIOps, further increase the interest in this research field and contribute to bridging the gap towards fully-autonomous operating IT systems.

Multi-Source Anomaly Detection in Distributed IT Systems

no code implementations13 Jan 2021 Jasmin Bogatinovski, Sasho Nedelkoski

Finally, we demonstrate that this formalization allows for the learning of template embedding for both the traces and logs.

Self-Attentive Classification-Based Anomaly Detection in Unstructured Logs

no code implementations21 Aug 2020 Sasho Nedelkoski, Jasmin Bogatinovski, Alexander Acker, Jorge Cardoso, Odej Kao

We propose Logsy, a classification-based method to learn log representations in a way to distinguish between normal data from the system of interest and anomaly samples from auxiliary log datasets, easily accessible via the internet.

Superiority of Simplicity: A Lightweight Model for Network Device Workload Prediction

1 code implementation7 Jul 2020 Alexander Acker, Thorsten Wittkopp, Sasho Nedelkoski, Jasmin Bogatinovski, Odej Kao

First, KPI types like CPU utilization or allocated memory are very different and hard to be expressed by the same model.
