Differential privacy: Balancing data privacy and utility in AI
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 NotesIntro 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 localWhy 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 dataSpeed up deployments of AI systems for enterprise customers since connections to raw data do not need to be establishedIncrease data security for customers that utilize sensitive data in their modeling systemsMinimize the risk of sensitive data exposure for your data privileges - i.e. Don’t be THAT organizationGuidelines and resources for applied differential privacyGuidelines for Evaluating Differential Privacy Guarantees: NIST De-IdentificationPractical 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 privacyCategorical 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 privacyData providers can’t provide us with anonymized data for analysis or when anonymization isn’t enough for our privacy needsHopeful that cohort targeting takes over for individual targetingRemember: Differential privacy does not prevent bias!What did you think?

Baseline modeling and its critical role in AI and business performance
Baseline modeling is a necessary part of model validation. In our expert opinion, it should be required before model deployment. There are many baseline modeling types and in this episode, we're discussing their use cases, strengths, and weaknesses. We're sure you'll appreciate a fresh take on how to improve your modeling practices.Show notesIntroductions and news: why reporting and visibility is a good thing for AI 0:03Spoiler alert: Providing visibility to AI bias audits does NOT mean exposing trade secrets. Some reports claim otherwise.Discussion about AI regulation in the context of current events and how regulation is playing out between Boeing and the FAA (tbc)Understanding baseline modeling for machine learning 7:41Establishing baselines allows us to understand how models perform relative to simple rules-based models, aka heuristics.Reporting results without baselines to compare against is like giving a movie a rating of 5 without telling the listener that you were using a 10-point scale.Baseline modeling comparisons are part of rigorous model validations and should always be conducted during early model development and final production deployment.Pairs with analyses of theoretical upper bounds for modeling performance to show how your technique scores between acceptable worst and best case performance.We often find complex models being deployed in the real world that haven’t proven their value over simpler and explainable baseline modelsClassification baselines and model performance comparison 19:40Uniform Random Selection - simulate how your model does against a baseline model that guesses classes randomly like a dice.Most Frequent Class (MFC) - the most telling test and often the most telling test in the case of highly skewed data with inappropriate metrics.Single-feature modeling - Validates how much the complex signal from your data and model improves over a bare minimum explainable model.And more…Exploring regression and more advanced baselines for modeling 24:11Regression baselines: mean, median mode, Single-variable linear regression, Lag 1, and Least 5% re-interpretationAdvanced baselines in language and visionConclusions 35:39Baseline modeling is a necessary part of model validationThere are differing flavors of baselines that are appropriate for all types of modelingBaselines are needed to establish fair and realistic lower bounds for performanceIf your model can’t perform significantly better than a baseline consider scrapping the model and trying a new approachWhat did you think?

Information theory and the complexities of AI model monitoring
In this episode, we explore information theory and the not-so-obvious shortcomings of its popular metrics for model monitoring; and where non-parametric statistical methods can serve as the better option. Introduction and latest news 0:03Gary Marcus has written an article questioning the hype around generative AI, suggesting it may not be as transformative as previously thought.This in contrast to announcements out of the NVIDIA conference during the same week.Information theory and its applications in AI. 3:45The importance of information theory in computer science, citing its applications in cryptography and communication.The basics of information theory, including the concept of entropy, which measures the uncertainty of a random variable.Information theory as a fundamental discipline in computer science, and how it has been applied in recent years, particularly in the field of machine learning.The speakers clarify the difference between a metric and a divergence, which is crucial to understanding how information theory is being misapplied in some casesInformation theory metrics and their limitations. 7:05Divergences are a type of measurement that don't follow simple rules like distance, and they have some nice properties but can be troublesome in certain use cases.KL Divergence is a popular test for monitoring changes in data distributions, but it's not symmetric and can lead to incorrect comparisons.Sid explains that KL divergence measures the slight surprisal or entropy difference between moving from one data distribution to another, and is not the same as KS test.Metrics for monitoring AI model changes. 10:41The limitations of KL divergence and its alternatives, including Jenson Shannon divergence and population stability index.They highlight the issues with KL divergence, such as asymmetry and handling of zeros, and the advantages of Jenson Shannon divergence, which can handle both issues, and population stability index, which provides a quantitative measure of changes in model distributions.The popularity of information theory metrics in AI and ML is largely due to legacy and a lack of understanding of the underlying concepts. Information theory metrics may not be the best choice for quantifying change in risk in the AI and ML space, but they are the ones that are commonly used due to familiarity and ease of use.Using nonparametric statistics in modeling systems. 15:09Information theory divergences are not useful for monitoring production model performance, according to the speakers.Andrew Clark highlights the advantages of using nonparametric statistics in machine learning, including distribution agnosticism and the ability to test for significance without knowing the underlying distribution.Sid MangaliWhat did you think?

The importance of anomaly detection in AI
In this episode, the hosts focus on the basics of anomaly detection in machine learning and AI systems, including its importance, and how it is implemented. They also touch on the topic of large language models, the (in)accuracy of data scraping, and the importance of high-quality data when employing various detection methods. You'll even gain some techniques you can use right away to improve your training data and your models.Intro and discussion (0:03)Questions about Information Theory from our non-parametric statistics episode.Google CEO calls out chatbots (WSJ)A statement about anomaly detection as it was regarded in 2020 (Forbes)In the year 2024, are we using AI to detect anomalies, or are we detecting anomalies in AI? Both? Understanding anomalies and outliers in data (6:34)Anomalies or outliers are data that are so unexpected that their inclusion raises warning flags about inauthentic or misrepresented data collection. The detection of these anomalies is present in many fields of study but canonically in: finance, sales, networking, security, machine learning, and systems monitoringA well-controlled modeling system should have few outliersWhere anomalies come from, including data entry mistakes, data scraping errors, and adversarial agents Biggest dinosaur example: https://fivethirtyeight.com/features/the-biggest-dinosaur-in-history-may-never-have-existed/Detecting outliers in data analysis (15:02)High-quality, highly curated data is crucial for effective anomaly detection. Domain expertise plays a significant role in anomaly detection, particularly in determining what makes up an anomaly.Anomaly detection methods (19:57)Discussion and examples of various methods used for anomaly detection Supervised methodsUnsupervised methodsSemi-supervised methodsStatistical methodsAnomaly detection challenges and limitations (23:24)Anomaly detection is a complex process that requires careful consideration of various factors, including the distribution of the data, the context in which the data is used, and the potential for errors in data entryPerhaps we're detecting anomalies in human research design, not AI itself?A simple first step to anomaly detection is to visually plot numerical fields. "Just look at your data, don't take it at face value and really examine if it does what you think it does and it has what you think it has in it." This basic practice, devoid of any complex AI methods, can be an effective starting point in identifying potential anomalies.What did you think?

What is consciousness, and does AI have it?
We're taking a slight detour from modeling best practices to explore questions about AI and consciousness. With special guest Michael Herman, co-founder of Monitaur and TestDriven.io, the team discusses different philosophical perspectives on consciousness and how these apply to AI. They also discuss the potential dangers of AI in its current state and why starting fresh instead of iterating can make all the difference in achieving characteristics of AI that might resemble consciousness. Show notesWhy consciousness for this episode?Enough listeners have randomly asked the hosts if Skynet is on the horizonDoes modern or future AI have the wherewithal to take over the world, and is it even conscious or intelligent? Do we even have a good definition of consciousness?Introducing Michael Herman as guest speakerCo-founder of Monitaur, Engineer extraordinaire, and creator of TestDriven.io, a training company that focuses on educating and upskilling mid-level senior-level web developers.Degree and studies in philosophy and technologyEstablishing the philosophical foundation of consciousnessConsciousness is around us everywhere. It can mean different things to different people.Most discussion about the subject bypasses the Mind-Body Problem and a few key theories:Dualism - the mind and body are distinctMaterialism - matter is king and consciousness arises in complex material systemsPanpsychism - consciousness is king. It underlies everything at the quantum levelThe potential dangers of achieving consciousness in AIWhile there is potential for AI to reach consciousness, we're far from that point. Dangers are more related to manipulation and misinformation, rather than the risk of conscious machines turning against humanity.The need for a new approach to developing AI systemsThere's a need to start from scratch if the goal is to achieve consciousness in AI systems.Current modeling techniques might not lead to AI achieving consciousness. A new paradigm might be required.There's a need to define what consciousness in AI means and to develop a test for it. Final thoughts and wrap-upIf consciousness is truly the goal, the case for starting from scratch allows for fairness and ethics to be established foundationallyAI systems should be built with human values in mindWhat did you think?
