Explaining the AI black box problem
TLDRTanya Hall interviews Sheldon Fernandez, CEO of Darwin AI, about the AI black box problem. Darwin AI specializes in making AI transparent by cracking open the black box. Fernandez explains that AI, particularly deep learning, is powerful but lacks transparency in its decision-making process. An example is an autonomous vehicle that turns left when the sky is a certain shade of purple, due to biased training data. Darwin AI uses AI to understand neural networks and validate explanations through a counterfactual approach. The importance of building foundational explainability for engineers and then translating it for consumers is highlighted.
Takeaways
- 🧠 The AI black box problem refers to the lack of transparency in how AI models, particularly neural networks, arrive at their decisions.
- 🐝 Darwin AI is known for developing technology to address the black box issue in AI, making AI decisions more understandable.
- 📈 AI systems like neural networks learn from vast amounts of data, but the process of how they learn is not easily understood by humans.
- 🦁 An example given is training a neural network to recognize lions by showing it millions of lion images, but it's unclear how the network internally processes this information.
- 🚗 A real-world example involves an autonomous vehicle that turned left when the sky was a certain shade of purple, due to biased training data from the Nevada desert.
- 🔍 To understand AI decisions, Darwin AI uses other AI techniques to interpret neural network behavior and provide explanations.
- 🔑 The key to validating AI explanations is using a counterfactual approach, which tests the validity of the AI's reasoning by altering input data.
- 📊 Darwin AI published research on a framework for testing AI explanations, showing their technique is superior to existing methods.
- 🌐 For those implementing AI, it's crucial to first establish a strong technical understanding of AI explainability.
- 🤝 Explainability is multi-level: it's important for developers to understand how AI works and for end-users to trust AI decisions, like in medical diagnoses.

Q & A
What is the AI black box problem?
-The AI black box problem refers to the lack of transparency in how artificial intelligence systems, specifically neural networks, make decisions. These systems can perform tasks effectively but do not provide insight into how they reach their conclusions.
Why is the black box problem significant in AI?
-The black box problem is significant because it can lead to AI systems making decisions for the wrong reasons, which can have serious consequences, especially in critical applications like autonomous vehicles or medical diagnostics.
What is Darwin AI known for?
-Darwin AI is known for developing technology that addresses the black box problem in AI by providing explanations for how AI systems make decisions.
How does Darwin AI's technology work?
-Darwin AI uses other forms of artificial intelligence to understand and explain the complex workings of neural networks, and then surfaces those explanations for humans to understand.
What is the counterfactual approach mentioned in the script?
-The counterfactual approach is a method used to validate the explanations generated by AI. It involves removing hypothetical reasons for a decision from the input and checking if the decision changes significantly, thereby confirming the validity of the explanation.
Why is it challenging to understand how neural networks make decisions?
-Neural networks are complex, with many variables and layers, making it mathematically infeasible to go through each one to understand what influences a particular decision.
Can you provide an example of the black box problem from the script?
-Yes, the script mentions an autonomous vehicle that turned left more frequently when the sky was a certain shade of purple. The AI had incorrectly correlated the color of the sky with the turning direction because it was trained in an environment where this correlation existed.
How does Darwin AI's research help in understanding AI decisions?
-Darwin AI's research provides a framework for generating and validating explanations of AI decisions, which helps in opening up the black box and understanding why AI is doing what it's doing.
What are the different levels of explainability mentioned in the script?
-The script mentions two levels of explainability: one for technical folks like engineers and data scientists, which helps in building robust AI systems, and another for consumers or end-users, which helps in understanding the AI's decisions.
How can someone get in touch with Sheldon Fernandez from Darwin AI?
-Sheldon Fernandez can be contacted through Darwin AI's website, DarwinAI.com, or on LinkedIn, and also via email at [email protected].
What recommendations does Sheldon Fernandez have for explaining AI decisions?
-Sheldon Fernandez recommends starting with technical understanding to ensure the AI system is robust and can handle edge cases. Once that foundation is built, explanations can be provided to non-technical end-users.
Outlines
🧠 Understanding the Black Box Problem in AI
Tanya Hall interviews Sheldon Fernandez, CEO of Darwin AI, to discuss the black box problem in artificial intelligence. Darwin AI is known for addressing this issue, which refers to the lack of transparency in AI decision-making processes. AI, particularly deep learning models, are trained on vast amounts of data but the internal workings that lead to their conclusions are not well understood. This can lead to AI systems making decisions for the wrong reasons, as illustrated by an example where an AI incorrectly associated a copyright symbol with images of horses. The conversation highlights the importance of cracking the black box to ensure that AI systems are making decisions based on real-world understanding rather than coincidental correlations in the training data.
🔍 Cracking the AI Black Box with Counterfactuals
Sheldon Fernandez explains how Darwin AI uses other forms of AI to understand and explain the complex workings of neural networks. The process involves a counterfactual approach where hypothetical reasons for AI decisions are tested by removing them from the input data to see if the decision changes significantly. This method was proven to be superior to existing techniques, as reported in Darwin AI's research published in December of the previous year. The discussion then shifts to the practical application of explainability in AI, emphasizing the need for different levels of explanation depending on the audience. For developers, understanding the AI's decision-making process is crucial for building robust systems, while for end-users, a simpler explanation that justifies the AI's output is necessary.
