The Bus Factor of XAI: Community Risk in Critical Open Source Explainability Tools

Key Points

• The aim is to assess the community risk associated with open source explainability tools in XAI.
• Analyzed various open source explainability tools to determine their bus factor.
• Evaluated the implications of the bus factor on community sustainability and tool reliability.
• Identified significant community risk due to low bus factors in critical explainability tools.
• Showed that a higher bus factor correlates with improved tool sustainability.
