DNN training and inference have similar basic operators but with fundamentally different requirements. The former is throughput bound and relies on high precision floating-point arithmetic for convergence while the latter is latency-bound and tolerant to low-precision arithmetic. Both workloads require high computational capabilities and can benefit from hardware accelerators. The disparity in resource requirements forces datacenter operators to choose between custom accelerators for training and inference or training accelerators for inference.
In their paper, the researchers introduce a nanowire-based device to create high-electron-mobility tri-gate transistors for power-conversion applications. Based on nanoscale structures, the novel transistor design significantly reduces heat loss during the energy conversion process.
Contrary to expectations, the experiment revealed that the respondents held on to their views firmly, regardless of the celebrity inputs or their esteem in the eyes of the respondents. It was also clear that respondents liked to hear an opinion identical to their own even if it came from a disliked celebrity. Conversely, a dissenting opinion by a celebrity or expert reduced the respondent’s empathy for that person.
Two EPFL students have developed PowerSGD, an algorithm that allows compression of the needed bandwidth without compromising the accuracy of the training.

About a year ago, when the novel coronavirus broke out, medical science not only failed to arrest its spread but also to properly identify the developmental stages of the disease. Many casualties resulted because the progression of the disease was an enigma. In the later part of the year, there were nascent attempts to harness AI for COVID-19 diagnosis, treatment, and monitoring. A giant step in that direction has been taken recently by researchers at EPFL; they have developed algorithms that can practically see and hear COVID in a patient’s lungs.

Given the fast pace of research, very few scientific studies stand the test of time. Even rarer is a study that continues to influence research a decade after its first publication. That distinction goes to “3D-ICE: Fast Compact Transient Thermal Modeling for 3D ICs with Inter-Tier Liquid Cooling,” a paper presented at the IEEE/ACM International Conference on Computer-Aided Design (ICCAD) 2010 Conference. It has been selected as the winner of the prestigious ICCAD 2020 - Ten Year Retrospective Most Influential Paper Award , which is one the most prestigious given in the Electronic Design Automation (EDA) community about industrial
One of the key researches in the domain of quantitative information flow (QIF) is to effectively estimate information leaks in a system in order to prevent adversarial attacks. Most existing approaches are based on the white-box approach. However, this approach is often impractical due to the size or complexity of its internals, or the presence of unknown factors. This and other challenges forced a shift in focus to investigate methods for measuring a system’s leakage in a black-box manner.
While scientists have successfully reduced the size and costs of electronic components, a major challenge faced by such tiny devices is the absence of an optimum thermal and energy management technology. To bridge that gap, Elison Matioli and his colleagues at EPFL’s Power and Wide-band-gap Electronics Research Laboratory (POWERlab) have developed a novel microchannel network that not only cools electronic components but also makes them energy efficient.

Data centers are taking on huge workloads including Deep Neural Networks, data analytics, and video streaming. Even the most robust CPU- and GPU-based architectures are unable to handle today’s demanding computing environment. Therefore, the current trend is to turn to new forms of accelerators called Field Programmable Gate Arrays (FPGAs), which demonstrate superior energy performance. Commercial behemoths like Intel, Amazon, and Microsoft have added FPGAs in their data centers through takeovers and system implementations. However, are FPGAs safe from security attacks? If not, how can such attacks be tackled? A fresh research proposal by EPFL’s Mirjana Stojilovic seeks to
The collaborative engagement between Microsoft and EPFL goes back to 2008 when they came together, along with ETH Zurich, for the Microsoft Innovation Cluster for Embedded Software (ICES).

In the latter list is “Training DNNs with Hybrid Block Floating Point,” which was presented by EPFL researchers Mario Drumond, Tao Lin, Martin Jaggi,
Teaching is an art, and not all teachers are blessed with that skill. It is one thing to deliver lectures to a classroom, and quite another to connect with the students in that classroom. Katerina Argyraki, Tenure Track Assistant Professor at EPFL’s School of Computer and Communication Sciences, clearly belongs to the rarer category of teachers who believe in understanding students’ aptitudes and tailoring lessons accordingly. It is, therefore, not at all surprising that she was recently chosen as "best teacher."
In early September, scientists, researchers, and industry leaders assembled in Rome for the 26th European Signal Processing Conference (EUSIPCO 2018). This year, the conference received 869 submissions, out of which about 550 were accepted. The reviewers sieved through those hundreds of important research papers to finally announce the Eurasip Best Student Paper Award. The authors of the winning paper are Mira Rizkallah (INRIA, visiting scholar at EPFL), Francesca De Simone (Post-doctoral fellow at EPFL), Thomas Maugey (INRIA), Christine Guillemot (INRIA), and Pascal Frossard (Associate Professor, EPFL).
Browsing websites is not without perils. With each visit, you leave some personal data that might be stored and even used by the website to their advantage. Data protection policies posted on websites are meant to make visitors wary of the danger, but the policies are either wrapped in incomprehensible legalese or clothed with seemingly innocuous generic terms that increase ambiguity about what a website does with your personal data. In February this year, researchers at EPFL launched an AI-backed program called Polisis to make life simpler by automatically scanning thousands of websites and generating an accurate and intelligible
In early July this year, the Board of the Swiss Federal Institutes of Technology appointed Mathias Payer as Tenure Track Assistant Professor in EPFL’s School of Computer and Communication Sciences. In a later development, Prof. Payer agreed to become a member of EcoCloud and share his expertise in protecting computer systems from malicious attacks.
The prestigious MICRO Test of Time (ToT) Award is an annual feature at the IEEE/ACM International Symposium on Microarchitecture. This year was the 51st edition of the conference, held between October 20 and 24 in Fukuoka City, Japan. In the course of the conference, the Awards Committee named Thomas Ball and James R. Larus as the winners of the fifth MICRO Test of Time Award. That is an honor for EPFL as well; Professor Larus is Dean of the School of Computer and Communication Sciences (IC).
Machine learning has become ubiquitous today with applications ranging from accurate diagnosis of skin cancers and cardiac arrhythmia to recommendations on streaming channels and gaming. However, in the distributed machine learning scheme, what if one ‘worker’ or ‘peer’ is compromised? How can the aggregation system be resilient to the presence of such an adversary?
Martin Jaggi, Tenure Track Assistant Professor at EPFL’s School of Computer and Communication Sciences, has won the Google Focused Research Award for 2018 in the area of Machine Learning.

In March 2016, EPFL and the International Committee of the Red Cross (ICRC) signed a seminal agreement to establish the Humanitarian Tech Hub. The four-year program has opened many avenues of collaboration between the scientific and humanitarian fields. To further cement that relationship, ICRC has just announced the appointment of EPFL’s Edouard Bugnion to the ICRC Assembly.
Web browsing has become almost second nature to us. Each day, we plunge into tens of websites and unwittingly accept their long-winded privacy policies without bothering to peruse their stipulations. This is undoubtedly because those documents are shrouded in legalese too dense and cumbersome to read and digest. Yet, it is a well-known fact that many websites collect, store, and even use the private data that we inadvertently leave behind during our browsing sessions. Disturbingly, such practices are usually protected by the legal jargon contained in their privacy policies. So how do we ascertain the nature of data collected
Geo-replication is gaining ground for distributed services because it brings the services closer to the end users, reduces the page-load time, and increases user engagement. It also enables data platforms, such as that of Facebook, to survive data center failures. However, recent work has proven that no distributed data system can assure the best of desirable properties like low-latency access, partition tolerance, and strong consistency.
Training of large-scale machine-learning models is extremely challenging because the training data is much more than the memory capacity. However, scientists at IBM and EPFL have collaborated to develop a novel scheme that enables the use of accelerators such as GPUs and FPGAs to speed up the training of machine learning models. They presented their findings at the 31st Annual Conference on Neural Information Processing Systems (NIPS) in Long Beach, California.
Machine learning and artificial intelligence (AI) are finding new applications across industries. Many tasks that were performed by humans are now being handled by machines, adding efficiency to the output. But what would happen if AI crosses the threshold of human control and makes unilateral decisions? It is a frightening, but highly probable, scenario. In 2014, it prompted Google to consider the idea of a “big red button” to stop dangerous AI in an emergency. However, the challenge is not in being able to stop or interrupt an AI process but in preventing AI from biased learning due to

The digital revolution is now all-pervasive, charting breakthroughs in computing and information technology. Driving that change is a group of leading innovators across the world. Among them is David Atienza, associate professor of Electrical and Computer Engineering and director of the Embedded Systems Laboratory at the School of Engineering, EPFL. In recognition of his outstanding scientific contributions to computing, the Association for Computing Machinery (ACM) has acknowledged him as a "pioneering innovator" and a "2017 Distinguished Member."
The widespread availability of video streaming services and the proliferation of smartphones have enabled users to do away with the need to download heavy content and thus save storage space on their devices. But the service provider—be it YouTube, Netflix, or any other—has to face serious challenges in offering a seamless experience to users. Two of the major concerns are storage space on their servers, and the resultant power consumption. Conversely, the user is confronted with challenges like bandwidth issues, unstable streaming flow, and video encoding issues. However, a solution is in the making to enhance the user experience
Providers of payment systems and password-protected applications use advanced computation to ensure security of their services. It is generally accepted that if large numbers are used in developing a code, it becomes extremely difficult to solve the math and break the code. In this process, computation of discrete logarithms plays a crucial part. Until recently, the record for computing a discrete logarithm was in the multiplicative group of a 596-bit prime field. However that has now been surpassed in a collaborative research between EPFL and the University of Leipzig. The team has cracked an extremely lengthy code by using
In April this year, researchers at EPFL’s School of Computer and Communication Sciences (IC) gained recognition for exemplary work in computer science. While Vasileios Trigonakis was awarded the 2017 Eurosys Roger Needham Doctoral Dissertation Award, Immanuel Trummer bagged Honorable Mention for the 2017 SIGMOD Jim Gray Doctoral Dissertation Award.
All our conscious decisions are focused on the extent of control exercised by the stakeholders. This applies to developing a new project, nurturing a new company, or even building communities. Traditionally, the overarching drive in such activities has been the retention of centralized authority. But times are changing, and so is the Internet, with yeomen researches on the benefits of a decentralized system. At the forefront of such researches is the work of PhD scholar and EPFL researcher Lefteris Kokoris-Kogias. His outstanding work has earned him the IBM PhD Fellowship for 2017.
