MAP5 is the Applied Math lab of Université de Paris that hosts Warith Harchaoui studying Generative and Discriminative AI for 4 wonderful years.
“A fascinating (and passionate) work which shows a beautiful hindsight on the field.”
Erwann Le Pennec, Professor at École Polytechnique and Ph.D. jury referee, 2021
During four life-changing years at MAP5 (2016-2020) within Université de Paris's applied math lab, Warith delved into the enthralling realm of Generative and Discriminative AI. Engaging deeply with neural networks and deep learning, Warith repurposed these potent tools. His work included pioneering clustering techniques with GANs, adept at organizing vast datasets, like categorizing myriad pixels in extensive photo collections. Warith also explored unsupervised feature importance, revealing distinctive dataset attributes without labels.
Additionally, the academic and corporate work was about methods to assess automated decision reliability, providing a crucial statistical approach for applications needing human oversight. This exploration, merging optimal transport mathematics with neural networks, reevaluated data representation. Thanks to the warmth of MAP5 and the pugnacity of Oscaro, Warith's journey modestly contributed to the field which is immense for him.
Afterwards, bringing home publications from top research conferences and journals brings a mixed feeling of pride, vanity and recognition, but also of course the emboldened drive to fight the next research battle in companies.
Oscaro.com is the worldwide leading e-commerce for car parts.
“This cooperation with the university brought great value to the company I founded, Oscaro, with the product Cerbero.”
Pierre-Noël Luiggi, founder of Oscaro.com, 2020
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.
We believe that Artificial Intelligence (AI) should be understood as an upheaval comparable to agriculture and sedentary life, the invention of writing or even printing. Those turning points altered our very relationship to the world.
All activities are now being affected by AI. For our everyday life, artificial intelligence is the automated emergence of certain aspects of natural intelligence such as learning, decision making, adaptation, prediction etc.
In practice, artificial intelligence is the science that allows machines to execute tasks from examples instead of instructions.
