Open Source, Open Data, Open Weights

Open Source has proven that removing barriers to learning, using, sharing, and improving software yield massive benefits for everyone. By applying these same principles to artificial intelligence—ensuring autonomy, transparency, frictionless reuse, and collaborative improvement—we can extend these gains to developers, deployers, and users alike.

probabl.ai was born at the heart of French scientific excellence at INRIA and builds on the legacy of the iconic scikit-learn project. Our mission: to set the highest industry standards for Open Source in Data Science. Through our commercial activities in certifications, products and consulting, we accelerate the diffusion of our innovations to the real economy.

🛜 Promoting Video Creators on the Internet

I asked my manager, Nicolas Renard, if I could quote this sentence 👆, and he responded by saying he agrees. Thank you, Nicolas, for being not only a super manager but also for your incredible and irreplaceable replacement for the MBA course at Rennes School of Business! 🙏🙏🙏

At Jellysmack, the team brings best efforts to help the web video creation space with cool projects in computer vision and natural language processing at the service of creators around the world.

The mission is twofold :
  ‣ igniting innovation through applied research prototypes
  ‣ offering research support to other artificial intelligence/machine learning teams by providing fresh, bibliographic, and pragmatic insights

We aim at inventing and improving the secret sauces, diligently crafting code deliverables, conducting scientific and technology watch, and engaging in internal and external talks.

Proudest achievement?

The video representation project, a combination of multiple kernel learning and Nyström approximation.

We meticulously gathered and harmonized the finest video representations available from research. With the invaluable insights from our media experts, we did not only infer our own combined similarity but also engineered fixed-sized vector representations for efficient grouping, retrieval, and success prediction estimation.

Additionally, we believe we revolutionize video editing leveraging the work of our hundreds of professional editors, optimizing rush-to-edit and short conversion processes for platforms like YouTube, Facebook, Instagram and TikTok. By analyzing multiple high-level signals and devising various splitting methods, we provide suggestions to editors, ensuring a seamless and creative editing experience minimizing the time spent on tedious non-artistic tasks.

Scientifically, it’s intellectually challenging to deal with videos because this medium is multimodal: image, sound, speech, music and motion. In terms of business, these fields is much rewarding when considering the success of videos and reduced time spent to build which clearly define our pragmatic performance indicators.

MAP5 is the Applied Math lab of Université de Paris that hosts Warith Harchaoui studying Generative and Discriminative AI for 4 wonderful years.

🎓 Math Lab

During four life-changing years at MAP5 (2016-2020) within Université de Paris's applied math lab, under the guidance of my supervisors Charles Bouveyron, we delved into the enthralling realm of Generative and Discriminative AI. Engaging deeply with neural networks and deep learning, we repurposed these potent tools. Indeed our work included pioneering clustering techniques with GANs, adept at organizing vast datasets, such as extensive photo collections. We also explored unsupervised feature importance, revealing distinctive dataset attributes without labels.

It was a happy coincidence that I met Dr. Élodie Germani during an internship I was lucky enough to supervise with Dr. Alkéos Michaïl. Élodie is now a researcher specialising in Artificial Intelligence for Medical Imaging.

Additionally, my academic and corporate work focused on methods to assess the reliability of automated decisions, providing a crucial statistical approach for applications requiring human oversight. This exploration merged mathematics from optimal transport and neural networks, helping us reevaluate data representation. Thanks to the warmth of MAP5 and the persistence of Oscaro, our journey modestly contributed to a field that we find immense and deeply meaningful.

🚘 E-commerce for car parts

At Oscaro.com, we participated in innovative initiatives as R&D Data Scientists, seamlessly blending deep learning and artificial intelligence to craft robust solutions. Our work was pivotal in implementing cutting-edge credit card fraud detection mechanisms, significantly mitigating risks and safeguarding transactions. Concurrently, we delved into demand forecasting, utilizing deep learning to accurately predict and adeptly respond to market dynamics, thereby driving efficiency and customer satisfaction.

Credit card fraud detection was a good example of asking ourselves the right questions: at the time, companies used to count errors, our approach consisted in counting the company's money loss. All systems in AI and beyond make mistakes: our job is to handle them in the most meaningful way. Thinking this way completely modifies the way you measure algorithm performances and also the way algorithms are rewarded and thus trained. It's also beneficial for management as the whole chain of command, even without AI knowledge, now understands what is optimized: the company's money. It turns out this approach made our career much easier with companies and clients.

Our role also encompassed AI technology watch, where we diligently monitored and analyzed emerging trends, research, and companies in the AI sphere, ensuring Oscaro.com stayed ahead in the competitive landscape. This commitment to excellence was further underscored by our pursuit of a Ph.D., generously funded from September 2016 to October 2020. Balancing from academic to work environments enriched our AI points of view, both feeding the common intellectual thirst.

Within the Oscaro.com group, there was the xBrain start-up, pioneering in chatbots and I had the pleasure of supervising an internship for Dr. Maxime Haddouche, who is now a researcher in Machine Learning and numerical optimisation.
