Have you ever heard the term “Black Box” in the context of artificial intelligence?

This concept refers to an intriguing phenomenon that occurs in many systems and machine learning or Deep Learning algorithms. Unlike traditional algorithms, which are programmed by humans, these systems learn autonomously through training processes that involve trial and error.

Imagine a student who adjusts their study method after each exam based on the results obtained. This is how machine learning works: the algorithm performs various actions, observes the results, and adjusts its behavior to improve its performance and accuracy. One of the most commonly used methods in this context is the Gradient Descent Algorithm, which seeks to minimize errors by adjusting parameters based on previous analyses, performed several times.

The Black Box Effect

But what does the black box effect mean?

This term refers to the lack of transparency or interpretability of algorithms, making it difficult or even impossible to understand why an AI system reaches certain conclusions or predictions.

A relevant example comes from the German Center for Scalable Data Analysis and Artificial Intelligence (ScaDS.AI), which investigates not only the efficacy of AI but also its ethics. It raises a crucial question: if we cannot understand how an AI algorithm makes decisions, how can we ensure that these decisions are fair and ethical? How can we prevent discrimination against certain groups?

Towards a Solution: Explainable AI

To address the black box problem, some techniques have been proposed, among them the increasingly popular explainable AI. This approach seeks to demystify the decision-making processes of algorithms, helping to prevent biases and errors.

White Box vs. Explainable AI

There are two factors within Explainable AI that we need to differentiate: interpretability and transparency. On one hand, there is interpretability, which focuses on answering the question: why has the model acted this way? On the other hand, transparency refers to: how does the model work?

While both concepts emphasize transparency and comprehensibility in AI systems, “white box effect” usually refers to the broader principle of transparency in systems, whereas “Explainable Artificial Intelligence (XAI)” is a more specific term within AI research focused on transparency through various techniques and methods.

Ideally, all models should be explainable and transparent so that all members or users can use, understand, and comprehend how a machine works.

Regulations and Norms in the European Union

In response to concerns about the “Black Box” and the need for greater transparency in artificial intelligence systems, the European Union has begun to implement specific regulations. One of the most prominent frameworks is the AI Act, which establishes strict requirements regarding the transparency, security, and accountability of AI systems. This regulation requires developers to provide clear and accessible explanations of how their algorithms make decisions, particularly in high-risk applications such as healthcare, justice, and employment.

Moreover, the General Data Protection Regulation (GDPR) already includes provisions that allow European citizens to question and understand automated decisions that affect them, thus reinforcing the approach towards a more explainable and ethical AI.

In a world increasingly driven by AI, it is essential that all models are explainable and transparent. This not only empowers users to understand how machines function but also fosters trust in technology. AI should not be a mystery; it should be an accessible and comprehensible tool for everyone.
