Collège Stanislas, 2021

Warith Harchaoui

Dear Professor,

On the second day of March in the year 2021, my friend Quentin and I paid you a visit in prep school Stanislas in Paris to express our gratitude on behalf of many students for imparting upon us the satisfaction mark. For almost two decades, I have made use of this punctuation, and it has made me feel as though I belong to a guild of enlightened scholars, much like yourself, who continue to teach us even today.

Think Tank 4^eRévolution, 2021

Warith Harchaoui and Laurent Pantanacce

Each industrial revolution is driven by a driving force: a raw material, an energy source, a creative technology that redefines the economy. Since the 19th century, we can list steam, coal, oil, electricity, radio, the transistor, computers, and today artificial intelligence (AI). This fourth industrial revolution is troubling because its commodity is abstract: data. At the scale of humanity, this seems a more significant milestone than a means of communication such as radio or the Internet. [...]

Electric Dreams, 2020

Olivier Frigara, Luc Julia and Warith Harchaoui

Luc Julia is the special guest on On refait le Mac. This Frenchman, co-creator of Siri, takes a look at his baby and why Apple's voice assistant is having so much trouble growing up. This world expert in artificial intelligence questions its real impact on our future. Should we believe the tech giants who predict that it will revolutionise everything? Should we be afraid? Let's debate!

From a single neuron, to a layer of neurons, then several layers, sometimes convolutional, and even several opposing neural networks, we are seeing certain aspects of the mystery of intelligence emerge through a technology that is changing the game in almost every area of our contemporary world.

Warith Harchaoui

In the rapidly advancing field of Artificial Intelligence, it is common to observe high volume and pace of both scientific and non-scientific publications. It is overwhelming and I am often asked how to do.
It is in this context that I present a list of books that I find particularly noteworthy, along with some comments, for those readers who are eager to engage in the exciting AI adventure.

We have created methods for geometrically connecting two piles of points, which is useful when these points are supposed to match. Our application example concerns the study of messenger RNA in genetics to understand Huntington's disease.

Clustering is the process of making groups among objects: similar within a group, dissimilar between two groups. The human mind naturally likes to form groups when it comes to customers, genes, fruits, animals and so on. The GEMINI project exploits artificial neural networks in a novel way for this large-scale task.

Ph.D. in Applied Mathematics, 2020

Warith Harchaoui
(supervised by Pr. Charles Bouveyron and Dr. Stéphane Raux)

From 2016 to 2020, this Ph.D. work focused on three key areas:

• Clustering: grouping large-scale data in number and dimension ;
• Importance of data features: identifying representative and discriminating features in data without the need for manual labels ;
• Confidence level estimation in automated decisions: creating statistical methods to assess the reliability of automated decisions, which is crucial in industry, security and healthcare.

The originality of this research lies in the way it combines the mathematical fields of optimal transport and neural networks in particular with generative artificial intelligence, which was in its infancy.
