In the digital era, Artificial Intelligence (AI) plays an increasingly central role in our daily lives. However, many of its internal mechanisms remain shrouded in mystery, encapsulated in what experts refer to as "black box" models. These complex systems, while extremely powerful, often lack something fundamental: interpretability.

Recent studies are paving the way to make these models not only more effective but also more understandable. Through the use of mathematical optimization methods, researchers are developing techniques to "open up" these black boxes, making AI more transparent and accessible to everyone.

Mathematical optimization, a branch of applied mathematics that deals with finding the best possible outcome within a given set of parameters, is proving to be crucial in this process. By employing advanced algorithms, it is possible to analyze and modify AI models to make them not only more efficient but also easier to interpret.

A recent study, titled "Supervised feature compression based on counterfactual analysis" (Piccialli, Veronica, Dolores Romero Morales, 2023), marks a significant step in this direction. The main goal of this work is to improve transparency and understandability using a technique called "counterfactual analysis." Counterfactual explanations seek to answer questions such as: "What would need to change in a given input to achieve a different outcome?" For example, if a model determines that a customer is not eligible for a loan, counterfactual analysis could indicate what changes in the customer's data could lead to a positive decision.

The article proposes a method to utilize the information obtained from counterfactual explanations to construct a decision tree, which is a type of machine learning model much easier to understand because it can be visualized as a series of binary questions and answers (yes/no). The created tree seeks to mimic the behavior of the original model but in a much more transparent form. The significant advantage of this approach is that it makes machine learning models more transparent and trustworthy, especially in sensitive sectors such as healthcare and finance, where understanding the "why" behind a decision can be crucial.

Mathematical optimization plays a crucial role in the article, being the key to implementing and improving the proposed methodology of supervised feature compression based on counterfactual analysis, allowing the authors to transition from an opaque and complex machine learning model to one that is more interpretable and transparent.

Numerical results on real-world datasets confirm the effectiveness of this approach, not only in terms of accuracy but also in reducing the complexity of the model. This study opens up new perspectives for making AI more transparent and trustworthy, a crucial step towards the ethical and responsible adoption of these technologies in our daily lives.

Deix stands out in the technological landscape thanks to its unique ability to integrate advanced expertise in applied mathematics, optimization, and numerical simulation with the most modern techniques of artificial intelligence and machine learning. This synergy creates a powerful combination that we call "Mathematical Intelligence." This approach not only improves the understanding and ethics of AI models but also significantly increases their reliability and accuracy.

Deix's experts, with solid academic roots and extensive experience in the fields of mathematical optimization and AI, are developing innovative methodologies to "decrypt" complex AI models. This pioneering work not only opens up new avenues in building transparent AI models but also sets a new standard for the responsible and conscious use of AI in critical contexts such as health, safety, and finance.

Deix's commitment to making artificial intelligence more accessible and understandable goes beyond mere technological improvement. The goal is to build solid trust between users and advanced technologies. By facilitating a greater understanding of how decisions are made by AI systems, Deix not only aims to democratize AI technology but also to strengthen the bond of trust with society. This transparency is essential for true accountability and social acceptance of advanced technologies.

Deix's commitment to **"Mathematical Intelligence"** is not just a matter of efficiency but an ethical choice aimed at ensuring that the technologies we build improve people's lives sustainably and fairly.

In conclusion, as we continue to navigate the complex world of AI, it is essential that we do not lose sight of the importance of transparency and interpretability. Research efforts in this field not only enhance our technological capabilities but also strengthen the bond of trust between humanity and the machines we choose to build.

Combining Technology and Sustainability to Create the Cities of the Future

Jacopo Corno, Head of Business Solutions at Deix, participated in a focus group as part of the European Desire project, which aims to transform the green transition into an irresistible and desirable reality. The event, organized by PlusValue at the MIND area (Milan Innovation District), provided a unique platform for professionals from various sectors to discuss and jointly design the city of the future.

The Desire project, part of the New European Bauhaus initiative of the European Commission, aims to bridge the gap between art, culture, education, science, and technology in the green transition. With the goal of engaging a new generation of green-social builders and artists, Desire adopts five design principles for the green transition: Circularity, Belonging, Biodiversity, Movement, and Aesthetics

In the context of the focus group, Deix played a fundamental role, highlighting how emerging technologies can be vital in data collection and analysis, in creating multimodal experiences, and in promoting a more sustainable and attractive environment.

A central theme that emerged during the focus group was the need to return to co-design. This collaborative approach, which combines different skills and experiences, is crucial for creating spaces that meet the needs of everyone. Deix emphasized the importance of integrating digital technology in this process, to ensure that the cities of the future. The event laid the groundwork for future collaborations between experts in urban planning, architecture, sustainable mobility, hospitality, and technology.

Deix's participation in the Desire project not only highlights the company's commitment to sustainability and innovation but also lays the foundation for a future where technology and design go hand in hand in creating greener, more inclusive, and beautiful urban spaces.
