Video Compression: A Neural Network Challenging the Conventional Approach

The rules were clearly defined so that innovations in the scientific community could be judged on the same criteria: some 100 videos of several seconds each needed to be compressed to 1 Mb/s, while retaining the best possible quality. Thirteen candidates submitted their coding for testing, with players from around the world, both in industry and […]

Self-supervised learning paves the way for a common-sense AI

In March 2021, the Facebook Artificial Intelligence Research (FAIR) laboratories unveiled a new computer vision model developed in cooperation with the French National Institute for Research in Digital Science and Technology (Inria). The particularity of this model, named “SEER” (for Self-supERvised), is that it has been pretrained on one billion random, unlabelled Instagram images, thanks […]

PINNs

The inventors of PINNs define them as “neural networks that are trained to solve supervised learning tasks while respecting any given law of physics described by general nonlinear partial differential equations”. Indeed, algorithms do not necessarily take into account the physical principles governing the systems to which they are applied. Yet, the behaviour of these […]

Artificial intelligence that is gentle, sensitive and distributed

The incredible progress made with Artificial Intelligence (AI) inspires hope that solutions may be found to some of humanity’s problems, for example problems relating to health or the environment. It does, however, also raise many fears, including the fear that a surveillance society is being created. Henri Sanson’s presentation looks at three major current […]

Behind the scenes of research: imagining the future of network diagnostics

The Research Exhibition marks a milestone in a project: it means that the project is now at a stage where it can be unveiled to the general public. Joachim Flocon-Cholet summarises things for the “Fault Diagnosis Discovery” demonstration as follows: when a customer calls an Orange call centre about a fault, the test launched on […]

AI, the anti-Covid toolbox

Sought after to respond to the COVID-19 health crisis, artificial intelligence (AI) has proven its effectiveness in several aspects of the fight against the pandemic, be it in understanding this new coronavirus, diagnosing it, predicting its evolution, slowing down its spread, or speeding up other aspects of medical research. Over a year after the crisis […]

Towards a less data and energy intensive AI

“It’s not who has the best algorithm that wins, it’s who has the most data.” This aphorism from artificial intelligence (AI) researcher Jean-Claude Heudin shows just how essential data is in machine learning. Deep learning algorithms in particular require a huge amount of annotated data (for supervised learning mode). However, data production is a long […]

The GPT-3 language model, revolution or evolution?

A new generation of language models In less than a decade, research in Natural Language Processing (NLP) has been overturned by the appearance of a suite of language models trained in an unsupervised manner on very large corpora. These models, trained to predict words, have proved capable of “capturing” the general linguistic characteristics of a […]

Inside the data centre of tomorrow

In order to reduce a data centre’s carbon footprint, one of the first steps is to supply it with renewable energies that provide a more carbon-free source of electricity. Many internet giants, operators and hosts already power all or part of their data centres with hydro, wind, and/or solar energy. In parallel, it is necessary […]

Vendée Globe 2020: innovation at the service of speed

On November 8th, 2020, 33 skippers set sail to tackle the “Everest of the seas”. This year again, the aim is clear: to break speed records. Armel Le Cléac’h, winner of the previous edition, made his round-the-world trip in 74 days. In 2020, the competitors hope to make it in less than 70 days. To achieve […]

AI breaks the sound barrier

The story of artificial intelligence and text recognition dates back many years, but sound recognition is a much more recent endeavour and, as a field of research, is still in the teething stages. The subtleties of sound are a major challenge for machines in terms of assimilation, and understanding those subtleties can be very difficult. […]

Behind the scenes of chatbot production

But behind these systems, sometimes referred to as examples of “artificial intelligence”, is a hybrid method of production combining automation and human control. Indeed, chatbots are devices that require a phase of knowledge expansion and then continuous supervision of the system. With this in mind, we examine how this human work is organised around algorithmic […]
