Explainable Generative AI (GenXAI): Challenges, Desiderata, and a Taxonomy for Enhancing Transparency and Accountability

Core Concepts

Generative AI (GenAI) has shown remarkable capabilities, but its widespread adoption raises the need for explainability to enhance transparency, accountability, and user control. This work identifies key challenges and desiderata for Explainable GenAI (GenXAI), and proposes a taxonomy to categorize existing and future XAI techniques for GenAI.

Abstract

The article discusses the importance of Explainable Artificial Intelligence (XAI) for Generative AI (GenAI) and the key challenges in achieving effective GenXAI. It highlights several novel aspects that make XAI more crucial and challenging for GenAI compared to pre-GenAI AI systems. The core motivation for GenXAI includes the need for users to adjust and verify GenAI outputs, the increased reach and impact of GenAI across diverse user groups, the difficulty in evaluating GenAI systems automatically, and concerns around security, safety, and accountability. The key challenges for GenXAI stem from the lack of access to model internals, the interactive and complex nature of GenAI systems, the difficulty in evaluating explanations, and the risk of ethical violations in explanations. The article then proposes several novel and emerging desiderata for GenXAI explanations, including verifiability, lineage, interactivity, personalization, dynamic explanations, consideration of costs, alignment with criteria like helpfulness and harmlessness, and ensuring security and conveying uncertainty. Finally, the article presents a taxonomy for categorizing GenXAI techniques based on the explanation properties (scope, modality, dynamics), as well as the input and internal properties of the XAI methods (foundational source, access requirements, self-explainers, sample difficulty, and dimensions from pre-GenAI XAI).

How can GenXAI techniques be designed to effectively support interactive exploration and personalization of explanations by diverse users?

GenXAI techniques can be designed to support interactive exploration and personalization of explanations by diverse users through several key strategies: User-Centric Design: GenXAI methods should prioritize user needs and preferences, allowing users to interact with the system in a way that suits their individual requirements. This can involve providing customizable interfaces, allowing users to adjust the level of detail in explanations, and offering options for different modalities of explanations (textual, visual, etc.). Interactive Feedback: Incorporating mechanisms for users to provide feedback on explanations can enhance the system's ability to personalize explanations over time. By allowing users to indicate the relevance and clarity of explanations, the system can adapt and improve its explanations based on user input. Dynamic Explanations: GenXAI techniques can offer dynamic explanations that adjust based on user interactions and feedback. This can involve tailoring the content and depth of explanations to match the user's level of expertise or specific information needs. Multi-Modal Explanations: Providing explanations in multiple modalities (text, images, videos) can cater to diverse user preferences and learning styles. Users can choose the format that best suits their understanding and engage with the explanations in a more interactive and personalized manner. User-Controlled Exploration: Allowing users to control the exploration of explanations by providing interactive tools such as sliders, filters, or search functionalities can empower users to delve deeper into specific aspects of the AI model's outputs. This level of control can enhance user engagement and understanding. By incorporating these design principles, GenXAI techniques can effectively support interactive exploration and personalization of explanations, catering to the diverse needs and preferences of users across different domains and expertise levels.

What are the potential trade-offs between providing comprehensive explanations and maintaining the security and intellectual property of GenAI systems?

Providing comprehensive explanations in GenXAI systems can sometimes pose challenges and trade-offs in terms of maintaining security and protecting intellectual property. Some potential trade-offs include: Information Leakage: Comprehensive explanations may reveal sensitive information about the AI model's architecture, training data, or decision-making processes. This could potentially expose vulnerabilities or proprietary algorithms, leading to security risks and intellectual property concerns. Reverse Engineering: Detailed explanations could enable malicious actors to reverse engineer the AI model, replicate its functionality, or exploit weaknesses in the system. This could compromise the security and competitive advantage of the organization that owns the GenAI system. Data Privacy: Comprehensive explanations may inadvertently disclose personal or confidential data used in the training or decision-making processes of the AI model. Protecting user privacy while providing detailed explanations can be a delicate balance to maintain. Complexity vs. Understandability: In some cases, providing overly comprehensive explanations may make it challenging for users to understand the reasoning behind the AI model's outputs. Balancing the depth of explanation with user comprehension is crucial to ensure effective communication without compromising security. Regulatory Compliance: Comprehensive explanations may need to adhere to regulatory requirements such as data protection laws or industry standards. Ensuring compliance while offering detailed insights into the AI system's operations can be a complex task that requires careful consideration of legal and ethical implications. Resource Constraints: Generating comprehensive explanations may require significant computational resources and time, impacting the performance and efficiency of the GenAI system. Balancing the need for detailed explanations with resource constraints is essential to maintain system usability and responsiveness. By carefully considering these trade-offs and implementing appropriate safeguards, GenXAI techniques can strike a balance between providing comprehensive explanations and safeguarding the security and intellectual property of GenAI systems.
