The Black Box Emergency | Javier Viaña | TEDxBoston
TLDRThe transcript highlights the urgent need to address the global issue of 'black box' artificial intelligence, where the complexity and lack of transparency in AI decision-making processes pose significant risks. The speaker emphasizes the importance of eXplainable Artificial Intelligence (XAI), which promotes algorithms whose reasoning can be understood by humans. Despite the challenges of integrating XAI due to size, unawareness, and complexity, the speaker advocates for the adoption of this approach to ensure trust, supervision, and regulation of AI systems. The concept of ExplainNets is introduced as a potential solution, using fuzzy logic to provide natural language explanations for neural networks, thereby paving the way for a more transparent and comprehensible AI future.

Q & A
What is the main issue with black box AI systems?
-The main issue with black box AI systems is that they are extremely complex and their internal workings are not understandable to humans. This lack of transparency prevents us from knowing how the AI arrives at its decisions or predictions, which can lead to potential misuse and a lack of trust in AI technologies.
Why is understanding the logic behind AI decisions important?
-Understanding the logic behind AI decisions is crucial for ensuring that AI systems are trustworthy, fair, and accountable. It allows for the supervision and validation of AI outputs, which is necessary for maintaining ethical standards and preventing potential harm or bias in AI-driven decisions.
What is eXplainable Artificial Intelligence (XAI)?
-eXplainable Artificial Intelligence (XAI) is a field of AI that focuses on developing transparent algorithms whose reasoning processes can be understood by humans. XAI aims to provide clear explanations for the decisions made by AI systems, thereby increasing trust, accountability, and the responsible use of AI.
How can explainable AI improve the current AI systems?
-Explainable AI can improve current AI systems by providing insights into the decision-making process of the algorithms. This transparency allows for better validation and auditing of AI models, helps in identifying and mitigating biases, and ensures that AI systems align with ethical and legal standards.
What are the challenges in adopting explainable AI?
-The challenges in adopting explainable AI include the size and complexity of existing AI pipelines, the unawareness of alternatives to neural networks, and the mathematical complexity of obtaining explainability. There is also a lack of standard methods in the field of explainability AI, which is still in its early stages of development.
What is the role of the General Data Protection Regulation (GDPR) in AI?
-The General Data Protection Regulation (GDPR) requires companies that process human data to explain the reasoning process behind their decisions to the end user. This regulation promotes transparency and accountability in AI systems, ensuring that users understand how their data is being used and how decisions are made.
How does the GDPR impact the use of black box AI systems?
-The GDPR impacts the use of black box AI systems by imposing fines on companies that fail to provide explainable reasoning processes to their users. This regulation incentivizes companies to move away from black box models and towards more transparent and explainable AI systems to comply with legal requirements and avoid financial penalties.
What are the two approaches to developing explainable AI?
-The two approaches to developing explainable AI are the bottom-up approach, which involves developing new algorithms that replace neural networks, and the top-down approach, which involves modifying existing algorithms to improve their transparency and explainability.
What is the top-down approach in explainable AI?
-The top-down approach in explainable AI involves modifying existing neural network algorithms to make them more transparent and understandable. This approach aims to provide insights into the reasoning process of the AI without the need to completely rebuild the AI system from scratch.
How do ExplainNets contribute to the field of explainable AI?
-ExplainNets contribute to the field of explainable AI by generating natural language explanations for the decision-making process of neural networks. Using mathematical tools such as fuzzy logic, ExplainNets aims to make the behavior of neural networks understandable to humans, thereby paving the way for more widespread adoption of explainable AI.
What is the potential consequence of not adopting explainable AI?
-If explainable AI is not adopted, there could be a loss of trust in AI systems and humanity, as well as an increased risk of blindly following AI outputs that may lead to failures and biases. This could result in AI indirectly controlling human decisions rather than humans controlling AI, which poses significant ethical and societal risks.
Outlines
🚨 The Global AI Emergency
The paragraph discusses the pressing issue of the excessive use of black box artificial intelligence systems, which are based on complex deep neural networks. These systems are high performing but their inner workings are not transparent, making them difficult to understand. The speaker highlights this as the biggest challenge in AI today, providing examples such as a hospital relying on AI for oxygen estimation and CEOs making decisions based on AI recommendations without understanding the logic behind them. The lack of explainability in current AI systems is alarming as it raises questions about who is truly making decisions, humans or machines.
💡 Introducing Explainable AI
This section introduces eXplainable Artificial Intelligence as a solution to the challenges posed by black box AI. Explainable AI promotes the use of transparent algorithms that can be understood by humans, contrasting with the opacity of black box models. The speaker emphasizes the importance of explainable AI in providing not just outputs but also the reasoning behind them, which is crucial for trust and effective use of AI systems. However, the speaker notes that current AI systems lack this explainability due to reasons such as the size and integration of existing AI pipelines, unawareness of alternatives, and the complexity of achieving explainability.
📣 Call to Action for Explainable AI
The speaker calls upon developers, companies, and researchers to adopt explainable AI, as it is essential for trust, supervision, validation, and regulation of artificial intelligence. The General Data Protection Regulation (GDPR) is mentioned as an example of regulation that requires companies to explain their reasoning processes, but despite fines, black box AI continues to be used. The speaker encourages consumers to demand explanations for AI used with their data and warns of a future where lack of supervision could lead to reliance on AI outputs without understanding, resulting in failures and a loss of trust in both humans and AI systems.
🛠️ Approaches to Achieving Explainable AI
The speaker outlines two approaches to developing explainable AI: a bottom-up approach that involves creating new algorithms to replace neural networks, which can be a complex task requiring advanced degrees, and a top-down approach that involves modifying existing algorithms to enhance their transparency. The speaker shares their work on a top-down architecture called ExplainNets, which uses fuzzy logic to generate natural language explanations for neural networks, thereby providing insights into their reasoning processes. The speaker believes that such human-comprehensible explanations are key to advancing the field of explainable AI.
