Liver cancer ranks third in terms of cancer-related mortality. Hepatocellular carcinoma (HCC) accounts for 90% of primary liver cancers. Tremendous efforts have been pursued to establish HCC prognostic, including clinical, radiological, pathological and even molecular readouts. Regardless of the strategy, the performance of these tools remains modest. Recent data using artificial intelligence (AI) on HCC histology (microscopy) have revealed promising results. We aim to submit pictures of liver cancers specimen to AI models to generate algorithms allowing to establish prognosis in a large-scale study including centers from North America, Europe and Asia.
State-of-the-art architectures for modulation recognition are typically based on deep learning models. However, recently these models have been shown to be quite vulnerable to very small and carefully crafted perturbations, which pose serious questions in terms of safety, security, or performance guarantees at large. While adversarial training can improve the robustness of the network, there is still a large gap between the performance of the model against clean and perturbed samples. Based on recent experiments, the data used during training could be an important factor in the susceptibility of the models. Thus, the objective of this project is to research the effects of proper data selection, cleaning and preprocessing of the samples used during training on robustness.
By 2025 the total amount of data created, captured and consumed is predicted to reach 175 zettabytes. However, much of that data’s value is being wasted due to distrust, as there is fear that the data would be exposed when used, computed on or shared with collaborators, possibly leading to trade secrets being leaked or data protection legislation fines.
I found this nice twitter thread from Vitalik Buterin, the inventor of the Ethereum blockchain: Doing a random twitter experiment just on this day. Only the 268 people I follow can reply to this tweet. Feel free to ask things and I'll talk about anything crypto or non-crypto related. — vitalik.eth (@VitalikButerin) September 1, 2021 (…)
The certificate linked to the virus will not be available before June in Switzerland. Until then, here are twelve answers linked to questions of security, data and accessibility concerning what some call the “Immunity Passport”. In particular, Jean-Pierre Hubaux, C4DT Academic Director, provides insights on the questions linked to data.
French-language news paper ‘Le Temps’ published an opinion piece by C4DT’s Academic Director and Head of the LDS lab at EPFL, Jean-Pierre Hubaux, on trusting the SwissCovid app. Prof. Hubaux raises the point that the excessive focus on privacy protection has cast doubt on a tool which makes it possible to defend other rights. Read the article in French on ‘www.letemps.ch’ by clicking the following link.
Increasingly, reports warn that state-sponsored actors use social media to spread fake news/disinformation in order to sow distrust and create panic during pandemics and create discord and polarized opinions among people on political issues during democratic elections. Adding to this, social media platforms’ algorithms “add salt to the wound” by feeding their users posts which are aligned with their opinion in order to increase their screen time. How serious and how massive is the problem? What are its implications? And what can/should be done about it?
During this forum, organized jointly by the Center for Digital Trust (C4DT), the CyberPeace Institute and the Graduate Institute’s Centre for Trade and Economic Integration (CTEI) in Geneva, we will discuss not only the technological aspects of this phenomena, but also the regulatory role executive and legislative branches of governments should play. Societal, economical and geopolitical implications will also be debated. This event is open to the general public.

Click is the prominent way that users interact with web applications. Attackers aim to intercept genuine user clicks to either send malicious commands to another application on behalf of the user or fabricate realistic ad click traffic. In this talk, Prof. Wei Meng investigates the click interception practices on the Web.

Interesting research, as Chinese open-weight models become default building blocks of open AI. It shows the limits of the self-hosting argument: running a model locally normally keeps data in, but the weaknesses in the code it writes still ship to production. If political alignment can change how securely a model codes, it is a supply-chain (…)
La justice électorale brésilienne a donné 24 heures à Meta pour prouver qu’elle traite de façon égale Lula et Flávio Bolsonaro, à égalité avant le second tour, sous peine d’une amende d’un million de reais par jour. Lula accuse la plateforme de brider ses contenus et son IA de favoriser son rival, ce que Meta (…)
Switzerland is taking a step further to try and protect its digital sovereignty. The Federal Office of Information Technology, Systems and Telecommunication recently published an invitation to tender for its new “Swiss Government Cloud”. With a hybrid multi-cloud approach, it will combine three coordinated cloud levels, based on data sensitivity (from global public cloud to (…)
Ich freue mich immer über die Erklärartikel von dnip. Dieser Artikel ist nicht nur eine einsteigerfreundliche Einführung in TLS-Zertifikate und ihre Rolle bei der Sicherung von Internetverbindungen , sondern auch gleich eine praktische Anleitung für den Umstieg auf souveränere Alternativen.
Au-delà de l’inquiétude que ces retraits institutionnels à la conférence de EU DisinfoLab suscitent, c’est surtout le risque d’autocensure qui doit alerter ici. Si traiter certains sujets coûte le soutien des institutions, d’autres organisateurs de conférence pourraient restreindre les thématiques de leurs programmes avant même d’être officialisés. Reste que, cette fois, la manœuvre a produit (…)
This article gives an interesting take on how autocratic rulers might become entrapped by the very technologies they use to control their populace, and points to concrete examples where AI is doing actual harm to societies today rather than the doomsday narratives Big Tech currently paddles. However, I feel it misses an opportunity to discuss (…)
Very interesting article about government requests to block illegal websites. The first blocks of this kind changed the DNS entries at the ISPs, but it very quickly turned out that you can change the DNS on your own computer. Cloudflare, which handles most of our internet traffic and also offers an uncensored DNS service, took (…)
I find this text both interesting and scary. The threat is twofold. Firstly, malicious actors contaminate the data that LLMs learn from. Secondly, they use AI to create content designed to persuade us. Filters should be able to identify and remove such propaganda. However, the second threat should hopefully have a positive side effect: people (…)

In brief: Unlocking data for AI should not mean handing it over. This 75-minute track shows, through working (…)
One of the problems with LLMs is that you can never be sure whether they’re inventing things, I call it “walking off a cliff”, or whether they’re still on solid ground. For programming, we have formal verification, and tools like TLA+, which allow you to model programs and reason about their state. LLMs are now (…)
