AI supercomputing for drug discovery

The time and costs associated with developing new drugs has risen dramatically. We need innovative new approaches more than ever. We are seeing promising breakthroughs: novel methods for molecular generation, genomics-at-scale, high accuracy protein folding prediction. But these methods are extremely computationally intensive, at a time when Moore's Law is finally failing. As the world leader in accelerated computing, NVIDIA is uniquely well placed to understand the future applications of AI supercomputing in drug discovery. This talk will describe the types of collaborations we are undertaking with partners like AstraZeneca and GlaxoSmithKline, and highlight where compute-as-scale has an invaluable role to play in the future of the field.

Learning across 16 million patients: Big data and HPC in healthcare

The London AI Centre partner hospitals provide care to 1⁄4th of the UK population. King’s College London, jointly with Imperial College and Queen Mary University of London, are building an AI and big-data infrastructure across 10 hospital trusts to deliver the vision of AI-enabled care. The infrastructure, built with privacy in mind, enables all clinical data (i.e. imaging, genetics, blood, pharmacy, interventions, medical decisions, costs) to be used for research, clinical and operational purposes, allowing algorithms to be trained on clinical data without the data ever leaving the hospital. In order to achieve this, we have built a large computing infrastructure within each hospital with the help of NVIDIA, and a centralised orchestration system to enable federated learning across multiple hospitals. This infrastructure has great potential for real-world impact, not only because it will enable access to data, but also because it aims to bring together large companies and early-stage start-ups (Industry), clinicians (hospitals), and scientists (university) into the same ecosystem.

Synthesizing high resolution medical volumes using 3D GANs

In this presentation I will show how 3D generative adversarial networks can be used to synthesize realistic medical volumes. As it is more challenging to share medical images, due to ethics and GDPR, synthetic volumes may be a solution to create large training datasets in medical imaging. This may be necessary to accelerate deep learning research in medical imaging, where a major hurdle is access to large datasets.

Learning vision is easy?

The visual cortex is a major area in the human brain and the majority of input from the environment is perceived by vision. Still, it was believed for decades that computer vision is a simple problem that can be addressed by student projects or clever system design based on concepts from related fields. About a decade ago, the field observed a major breakthrough with the advent of deep learning, to a large extent enabled by means of novel computational resources in form of GPUs. Since then, the field basically exploded and thousands of black-box approaches to solve vision problems have been developed. However, it turned out that previously known concepts such as uncertainty and geometry are still relevant when we want to better understand deep learning methods and achieve state of the art performance.

SciLifeLab-KAW Data-Driven Life Science (DDLS) program: the promise of a national program at the launch phase

Life science has become increasingly data-centric, data-dependent and data-driven. There is an exponential growth of data in terms of quantity and complexity. The importance of data has been further emphasized by the pandemic and the quest for real-time access to Covid-19 research data and the growing need to make rapid data-dependent informed decisions. The SciLifeLab and Wallenberg National Program on Data-Driven Life Science (DDLS) was launched in 2021 with a mission to recruit and train the next-generation of computational life scientists, create national data handling capabilities and collaborative research programs in four areas of data-driven life science, i) molecular and cellular biology, ii) biodiversity and evolution, iii) biology and epidemiology of infection and iv) precision medicine and diagnostics. The program is funded by the Knut and Alice Wallenberg (KAW) foundation with up to 3,2 BSEK over 11 years and is coordinated by the National Life Science Infrastructure SciLifeLab. The program will engage 11 partners (KTH, KI, SU, UU, UmU, SLU, LiU, CHT, GU, LU, and NRM), recruit some 40 new group leaders and train 100s of PhD students and postdocs, contribute to national data handling infrastructure and FAIR practices and to data analysis capabilities as well as collaborate with the WASP program and with industry. This presentation will describe the DDLS program and provide examples on recent data-driven life science breakthroughs.

Learning compositional, structured, and interpretable models of the world

Despite their fantastic achievements in fields such as Computer Vision and Natural Language Processing, state-of-the-art Deep Learning approaches differ from human cognition in fundamental ways. While humans can learn new concepts from just a single or few examples, and effortlessly extrapolate new knowledge from concepts learned in other contexts, Deep Learning architectures generally rely on large amounts of data for their learning. Moreover, while humans can make use of contextual knowledge of e.g. laws of nature and insights into how others reason, this is highly non-trivial for a regular Deep Learning algorithm. There are indeed plenty of applications where estimation accuracy is central, where regular Deep Learning architectures are purposeful. However, models that learn in a more human-like manner have the potential to be more adaptable to new situations, more data efficient and also more interpretable to humans - a desirable property for Intelligence Augmentation applications with a human in the loop, e.g. medical decision support systems or social robots. In this talk I will highlight projects in my group where we explore object affordances, disentanglement, multimodality, and cause-effect representations to accomplish compositional, structured, and interpretable models of the world.

FAIR life science data on Berzelius

In life science, the data analyzed comes from biological systems that are often difficult to study for many reasons. These systems are for example often complex, open, noisy, spanning widely different spatiotemporal scales, and governed by nonlinear dynamical processes. Life science is now going through a transformative period, thanks to the combination of rapidly advancing measurement technologies, powerful new compute resources and strong bioinformatics algorithm development that utilizes the new computer architectures, enabling us to analyze the underlying biological systems. But one particularly important component in this progress has been the data sharing that has been developed by the life science community for decades, leading to the recent principles for Open Science and FAIR data. The Berzelius system now provides Swedish researchers with unparalleled compute capacity for AI/ML, and in this presentation, I will discuss how life science data will come to Berzelius for analysis and how the results will be shared.

Artificial Intelligence, Computational Fluid Dynamics and Sustainability

The advent of new powerful deep neural networks (DNNs) has fostered their application in a wide range of research areas, including more recently in fluid mechanics. In this presentation, we will cover some of the fundamentals of deep learning applied to computational fluid dynamics (CFD). Furthermore, we explore the capabilities of DNNs to perform various predictions in turbulent flows: we will use convolutional neural networks (CNNs) for non-intrusive sensing, i.e. to predict the flow in a turbulent open channel based on quantities measured at the wall. We show that it is possible to obtain very good flow predictions, outperforming traditional linear models, and we showcase the potential of transfer learning between friction Reynolds numbers of 180 and 550. These non-intrusive sensing models will play an important role in applications related to closed-loop control of wall-bounded turbulence. We also draw relevant connections between the development of AI and the achievement of the 17 Sustainable Development Goals of the United Nations.

The AI revolution in structural biology

Protein structure prediction is a classical problem in structure biology: Given the building blocks of the protein, the protein sequence, the protein adopts a unique 3D structure to perform its function. The protein sequence is easy to get experimentally but the 3D structure (i.e. the x, y, z coordinates for each atom in the structure > 10,000 atoms) requires hard work and can takes years to determine experimentally. Thus, having methods that from sequence can predict the 3D structure would revolutionize structural biology. During the last years DeepMind (a Google owned company) have been working on this problem using AI, and last year they presented a solution that demonstrated unprecedented performance - AlphaFold. AlphaFold is an end-to-end method that is able to take the protein sequence as input and generated 3D coordinates of all atoms in a conformation that is often close to the coordinates would take years to obtain experimentally. This summer, DeepMind released AlphaFold open source, making the tool available to everyone. The AI revolution in structural biology had begun. In the talk I will focus on the technical aspects of AlphaFold and how we have used Berzelius to understand and also improve certain aspects of AlphaFold.

An overview of the Wallenberg AI, Autonomous Systems and Software Program (WASP)

This presentation will take its starting point in the underpinning trends in society that motivated the initiation of the WASP program in 2015. WASP is the largest individual research program in the Swedish funding history with a total budget of 5.5 BSEK over 15 years. The ambition of the program is to graduate 600 PhDs and to establish 80 new research groups in the WASP domain. A clear focus of a large fraction of the WASP projects is the development and use of machine learning approaches. In view of this, access to large scale resources tailored to AI applications is of highest possible importance to WASP. During 2021 WASP has initiated a number of new instruments such as the NESTs program and collaborations with the Data-Driven Life Science (DDLS) program. The presentation will conclude with an overview of these instruments and their current status.
