What if the secret to successful AI governance lies in understanding the evolution of model documentation? In this episode, our hosts challenge the common belief that model cards marked the start of documentation in AI. We explore model documentation practices, from their crucial beginnings in fields like finance to their adaptation in Silicon Valley. Our discussion also highlights the important role of early modelers and statisticians in advocating for a complete approach that includes the entire model development lifecycle.

Model documentation origins and best practices (1:03)

• Documenting a model is a comprehensive process that requires giving users and auditors clear understanding:
  • Why was the model built?
  • What data goes into a model?
  • How is the model implemented?
  • What does the model output?

Model cards - pros and cons (7:33)

• Model cards for model reporting, Association for Computing Machinery
• Evolution from this research to Google's definition to today
• How the market perceives them vs. what they are
• Why the analogy “nutrition labels for models” needs a closer look

System cards - pros and cons (12:03)

• To their credit, OpenAI system cards somewhat bridge the gap between proper model documentation and a model card.
• Contains complex descriptions of evaluation methodologies along with results; extra points for reporting red-teaming results
• Represents 3rd-party opinions of the social and ethical implications of the release of the model

Automating model documentation with generative AI (17:17)

• Finding the balance in automation in a great governance strategy
• Generative AI can provide an assist in editing and personal workflow

Improving documentation for AI governance (23:11)

• As model expert, engage from the beginning with writing the bulk of model documentation by hand.
• The exercise of documenting your models solidifies your understanding of the model's goals, values, and methods for the business

Are businesses ready for large language models as a path to AI? In this episode, the hosts reflect on the past year of what has changed and what hasn’t changed in the world of LLMs. Join us as we debunk the latest myths and emphasize the importance of robust risk management in AI integration. The good news is that many decisions about adoption have forced businesses to discuss their future and impact in the face of emerging technology. You won't want to miss this discussion.

  • Jan LeCun's energy systems and retrieval-augmented generation (RAG) offer intriguing alternatives that could reshape modeling approaches
• The ethics of advancing AI technologies, consider the parallels with past monumental achievements and the responsible allocation of resources (00:26:49)
  • There is good news about developments and lessons learned from LLMs; but there is also a long way to go.
  • Our original predictions in episode 2 for LLMs still reigns true: “Reasonable expectations of LLMs: Where truth matters and risk tolerance is low, LLMs will not be a good fit”
  • With increased hype and awareness from LLMs came varying levels of interest in how all model types and their impacts are governed in a business.

  • Non-linearity and how it exists in the natural world
• Chaos and randomness [00:11:30]
  • Enter references to Jurassic Park and The Butterfly Effect
  • “In universe simulations, a change to a single parameter can govern if entire galaxy clusters will ever form” - Rachel

Can your AI models survive a big disaster? While a recent major IT incident with CrowdStrike wasn't AI related, the magnitude and reaction reminded us that no system no matter how proven is immune to failure. AI modeling systems are no different. Neglecting the best practices of building models can lead to unrecoverable failures. Discover how the three-tiered framework of robustness, resiliency, and anti-fragility can guide your approach to creating AI infrastructures that not only perform reliably under stress but also fail gracefully when the unexpected happens.

Show Notes

• Technology, incidents, and why basics matter (00:00:03)
  • While the recent Crowdstrike incident wasn't caused by AI, it's impact was a wakeup call for people and processes that support critical systems
  • As AI is increasingly being used at both experimental and production levels, we can expect AI incidents are a matter of if, not when. What can you do to prepare?

• The "7P's": Are you capable of handling the unexpected? (00:09:05)
  • The 7Ps is an adage, dating back to WWII, that aligns with our "do things the hard way" approach to AI governance and modeling systems.
  • Let’s consider the levels of building a performant system: Robustness, Resiliency, and Antifragility

• Model robustness (00:10:03)
  • Robustness is a very important but often overlooked component of building modeling systems. We suspect that part of the problem is due to:
    • The Kaggle-driven upbringing of data scientists
    • Assumed generalizability of modeling systems, when models are optimized to perform well on their training data but do not generalize enough to perform well on unseen data.

• Model resilience (00:16:10)
  • Resiliency is the ability to absorb adverse stimuli without destruction and return to its pre-event state.
  • In practice, robustness and resiliency, testing, and planning are often easy components to leave out. This is where risks and threats are exposed.
  • See also, Episode 8. Model validation: Robustness and resilience

• Models and antifragility (00:25:04)
  • Unlike resiliency, which is the ability to absorb damaging inputs without breaking, antifragility is the ability of a system to improve from challenging stimuli. (i.e. the human body)
  • A key question we need to ask ourselves if we are not actively building our AI systems to be antifragile, why are we using AI systems at all?

Explore the basics of differential privacy and its critical role in protecting individual anonymity. The hosts explain the latest guidelines and best practices in applying differential privacy to data for models such as AI. Learn how this method also makes sure that personal data remains confidential, even when datasets are analyzed or hacked.

Show Notes

• Intro and AI news (00:00)
  • Google AI search tells users to glue pizza and eat rocks
  • Gary Marcus on break? (Maybe and X only break)
• What is differential privacy? (06:34)
  • Differential privacy is a process for sensitive data anonymization that offers each individual in a dataset the same privacy they would experience if they were removed from the dataset entirely.
  • NIST’s recent paper SP 800-226 IPD: “Any privacy harms that result form a differentially private analysis could have happened if you had not contributed your data”.
  • There are two main types of differential privacy: global (NIST calls it Central) and local
• Why should people care about differential privacy? (11:30)
  • Interest has been increasing for organizations to intentionally and systematically prioritize the privacy and safety of user data
  • Speed up deployments of AI systems for enterprise customers since connections to raw data do not need to be established
  • Increase data security for customers that utilize sensitive data in their modeling systems
  • Minimize the risk of sensitive data exposure for your data privileges - i.e. Don’t be THAT organization
• Guidelines and resources for applied differential privacy
  • Guidelines for Evaluating Differential Privacy Guarantees:
  • NIST De-Identification
• Practical examples of applied differential privacy (15:58)
  • Continuous Features - cite: Dwork, McSherry, Nissim, and Smith’s 2006 seminal paper "Calibrating Noise to Sensitivity in Private Data Analysis”[2], introduces a concept called ε-differential privacy
  • Categorical Features - cite: Warner (1965) created a randomized response technique in his paper titled: “Randomized Response: A Survey Technique for Eliminating Evasive Answer Bias”
• Summary and key takeaways (23:59)
  • Differential privacy is going to be a part of how many of us need to manage data privacy
  • Data providers can’t provide us with anonymized data for analysis or when anonymization isn’t enough for our privacy needs
  • Hopeful that cohort targeting takes over for individual targeting
  • Remember: Differential privacy does not prevent bias!
