Encrypting or classifying Internet traffic: do we have to choose?

Internet traffic encryption yesterday, today and tomorrow Traffic encryption is the practice that aims to make data exchanged over networks incomprehensible to unauthorized observers. Figure 1: End-to-end traffic encryption on the Internet On the Internet, traffic encryption was popularized by Netscape, with the introduction of SSL, the ancestor of TLS, in 1995 and has grown […]

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 […]

Using AI to monitor movement promises to improve home care

By 2050, there will be two billion people in the world aged 60 and over, which is twice as many as in 2020 (source: WHO). In addition, there are currently 40 million people affected by severe disability. For all these people, receiving sufficient health care at home while maintaining a level of autonomy is a critical yet […]

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 […]

5 cutting-edge technologies that are changing the game

Energy: blockchain is speeding up microgrids The features of blockchain could be a lever for modernising the energy system. Blockchain enables the distributed, secure, transparent recording and storage of energy and transaction flows. It can be used to track energy consumption in real time or to have knowledge of the asset portfolios of all participants. […]

Neuroprosthetics, virtual reality, and AI tackle motor disabilities

The Clinatec research centre’s Brain Computer Interface (BCI) project “For the first time, a tetraplegic patient was able to walk and control both arms using this neuroprosthetic, which records, transmits, and decodes brain signals in real-time to control an exoskeleton”, the French Alternative Energies and Atomic Energy Commission (CEA) proudly announced in October 2019. Developed […]

Robotics, AI and blockchain at the heart of the healthcare of tomorrow

Robotics and digital imaging fostered the development of “minimally invasive” techniques. The convergence of intensive computing and artificial intelligence (AI) is now speeding up basic and clinical medical research, and is fostering the development of healthcare that is both personalised and predictive. As for blockchain, it offers a framework that helps address the challenges brought […]

Brain-Computer Interface

A Brain-Computer Interface is a Human-Machine Interface (HMI) of a particular kind, as it provides direct communication with the human brain. Through thought, a user can thus remotely control a computer or a smart object. Freed from the chain of psychomotor reactions between the brain, the nerves, and the muscles, a BCI delivers much shorter […]

Fake news: will advances in technology help us to distinguish between true and fake?

Social networks are fertile ground for spreading lies that are knowingly presented as legitimate information. Exposing them is often simple. Critical thinking, civic-mindedness, and media education can often suffice to foil misinformers’ strategies. However, doctored videos, called deep fakes, are in certain cases more and more difficult to identify as such. These composite videos create […]
