So your question about whiteness is working on that. NIST has a very broad portfolio of research and a long standing tradition of cultivating trust in technology. And we do that by advancing measurement science, advancing technical standards that make technology more robust, secure, private, in other words, more trustworthy. And that's exactly what we're doing in there you have aI through our foundational research, but also, as I said, NIST has a very broad portfolio of research. So AI scientists also using AI as a scientific discovery in their research. So we get to see how AI is being used, and also work on foundation concepts of what constitutes constitute trust and what trustworthy AI looks like, about the AI RMF AI risk management framework directed by congressional mandate. Ai RMF is a voluntary framework for managing the risk of AI systems in a flexible, structured and measurable way. Flexible to first and foremost, allow for innovation to happen but also allow for different organizations with different level of resources, be able to adopt it and use it structured in terms of that it starts by trying to provide some sort of a lexicon, you know, unified lexicon and vocabulary about what's AI system, what's the risk of AI systems, how the risk of AI systems differs from the risk of any other information or data systems. And with that sort of lays out why another framework is needed for managing the risk of AI systems. And it's measurable and that's really near and dear to our heart, because if you cannot measure it, you cannot improve it. So, if you really want to improve the trustworthiness of AI systems, any approach for risk management any approach for understanding the trustworthiness should also provide metrology for how to measure trustworthiness. It adopts a rights preserving approach and provide an outlines processes for understanding and measuring traditional measures such as validity, reliability, accuracy, but also importantly acknowledge socio technical characteristics such as privacy interpretability, transparency, security, bias, and outlines processes for understanding and managing them. These characteristics are tied to human behavior and they cannot be summarized into a single number and be measured with a single threshold. It was released on January 26. Very quickly to answer your questions about generative AI. So Of course, the church up at the release of chat GBT in November captured a lot of attention across the media and everywhere but but a lot of us in the AI field were aware of these things, whatever of this generative AI systems, and we were thinking about this very quickly AI RMF. The way it defines AI systems, that definition is definitely applicable to generative AI, it was by design for something that we had our eyes on it. And the second thing is that risk based approach is a very powerful approach. And if it's done correctly, it's also flexible to allow for all of these different innovations that happen. Well, granted, understanding the risk profile of a generative AI such as Chad JpT is going to be a lot more complicated and complex, I have a risk profile of a deep neural net, which is more complicated and complex than a logistic regression. But at the end, what's important is to have a structured way of understanding risk a good taxonomy of risks and, and methods and measure to afford measuring them. If I'm, if I have time, I just want to say a few words about AI RMF has been developed in an open transparent, collaborative process. It started with a request for information, rounds of workshops, rounds of draft for public comments. And in the span of 18 months, we heard from more than 200 for the organization's receives more than 600 sets of comments. And the the outreach and engagement was from a tech community to civil society to legal scholars. On our team, we consulted with psychologists and sociologists, we have cognitive scientists are on our on our team, because again, AI systems is all about context and risk management cannot be done without understanding the context and the from the socio technical lens and approach.
