Language Models for Novelty Detection in Kernel Traces

Description of the project

How to collect data

1. Deploy the server: setup-server.md

2. Deploy the client: setup-client.md

3. OPTIONAL Update the LTTng headers if necessary: update-header.md

4. Collect the trace: trace.md

5. Generating OOD behaviors setup-ood.md

A toy dataset is available in data/toy and a large dataset is available at https://zenodo.org/record/7378420.

How to Analyse the Trace

1. Deploy the analysis environment:

   • Locally setup-analysis.md
   • On Compute Canada setup-graham.md

2. Execute the experiment script:

   bash experiments.sh

How to run the analysis
