- Will AI manipulate public opinion, increase social echo chambers, create educational biases, accelerate disinformation, and destroy democracy itself?
- Will AI-driven marketing become so powerful we will lose all ability to make our own decisions?
- Will militarized AI attack the innocent? Will robots start their own wars, or just decide humans are ridiculous and eliminate us altogether on the basis of a cold and murderous logic?
People are asking questions about AI which require answers if we are to increase public trust in AI, and help educate the public to play a strong role in taking advantage of what AI has to offer while empowering them to help steward an ethical and human-centered evolution of the technology.
This is where AI transparency and explainability comes in.
What is AI Transparency? What is AI Explainability? What’s the difference?
AI transparency and explainability, while interconnected, serve distinct purposes in the realm of artificial intelligence.
What is AI Transparency?
AI transparency is about the visibility and openness of an AI system’s design, data, and operation. It involves disclosing detailed information about the AI’s development process, data used for training, functioning mechanisms, and deployment process.
AI transparency addresses challenges such as potential biases, ethical dilemmas, and compliance with regulatory standards, emphasizing the need for AI systems to be not only technically proficient but also understandable and interpretable by humans.
What is AI Explainability?
AI explainability, focuses on making the complex decisions and outputs of an AI system understandable to users, regardless of their technical expertise.
With transparency, an engineer who understands the impact of training data on an AI model designed for the financial industry. But will your grandmother understand why she was denied a loan by a financial system and what she can do about it? Maybe she can if your grandmother is an engineer. But if not, explainability can help her navigate a technology-driven real-world situation in a human, intuitive manner.
An Example of How AI Transparency and Explainability Work Together
Consider a financial institution using an AI system for credit scoring.
AI Transparency: The institution ensures transparency by disclosing how the AI model was developed, the types of data it was trained on (e.g., credit history, income levels), and the overall mechanism by which it evaluates creditworthiness. This transparency allows for an understanding of what data the AI uses and its general operational principles.
AI Explainability: When an applicant receives a credit score from this AI system, explainability comes into play. The institution provides a clear, understandable explanation to the applicant about why a particular credit score was assigned. For instance, the AI might highlight that the score was influenced by factors such as recent payment history or debt-to-income ratio, explained in a way that a non-expert can comprehend.
In this use case, transparency allows stakeholders to know what goes into the AI system and how it generally functions, while explainability allows the end-users, the credit applicants, to understand the specific reasoning behind their individual credit scores. Both elements working together ensure that the AI system is not only open about its processes but also accessible in its decision-making.
