Artificial intelligence is part of our modern life by enabling machines to learn useful processes such as speech recognition and digital personal assistants. A crucial question for practical applications is how fast such intelligent machines can learn. An experiment at the University of Vienna has answered this question, showing that quantum technology enables a speed-up in the learning process.

By Christoph Pelzl Researchers at TU Graz demonstrate a new design method for particularly energy-saving artificial neural networks that get by with extremely few signals and - similar to Morse code - also assign meaning to the pauses between the signals. Most new achievements in artificial intelligence (AI) require very large neural networks.

Quantum technologies for computers open up new concepts of preserving the privacy of input and output data of a computation. Scientists from the University of Vienna, the Singapore University of Technology and Design and the Polytechnic University of Milan have shown that optical quantum systems are not only particularly suitable for some quantum computations, but can also effectively encrypt the associated input and output data.

By Christoph Pelzl Using mathematical image processing, scientists at the BioTechMed-Graz research cooperation have found a way to create digital twins from human hearts. The method opens up completely new possibilities in clinical diagnostics.

By Cornelia Kröpfl BA MA When cars drive autonomously, technical faults can be fatal. Can we trust technology? Researchers at Graz University of Technology are working on calculating and ultimately proving this dependability. 75 billion everyday objects - from the smart watch and the self-driven car to entire production plants in Industry 4.0 - are to be joined up by 2025.

By Cornelia Kröpfl BA MA 30 years ago, data security was a niche topic. Today, researchers at TU Graz are laying the foundations for a completely new way of thinking about security. Including future developments. Not so long ago, the mobile phone was primarily used to store contact data. Today, smartphones know where we are and what media we read.

By Barbara Gigler SGS and TU Graz announce the opening of Lamarr Security Research, a non-profit research center focusing on information security and establishing trust in digital systems and products. This new research environment is open for partner sponsors to work together, and to make the world a safer place.

By Christoph Pelzl An international team of security researchers from TU Graz, CISPA and University of Birmingham is presenting new side-channel attacks, which use fluctuations in software power consumption to access sensitive data on Intel CPUs. Power side-channel attacks are attacks that exploit fluctuations in power consumption to extract sensitive data such as cryptographic keys.

By Christoph Pelzl TU Graz algorithm-based method provides a basis for decisions on the correct amount of tamping measures on tracks, thus reducing their life-cycle costs by up to 20 per cent. Train journeys should be safe and comfortable, and track systems are crucial to this. So-called "tamping" (positioning, compacting and stabilizing) of the ballast in the track bed is one of the most important maintenance tasks in the railway industry.

Artificial intelligence (AI) can become more efficient and reliable if it is made to mimic biological models. New approaches in AI research are hugely successful in experiments. Artificial intelligence has arrived in our everyday lives-from search engines to self-driving cars. This has to do with the enormous computing power that has become available in recent years.

A human research team and a machine learning algorithm have found that we need to rethink much of what we know about iridium oxide.

By Susanne Eigner Researchers at TU Graz and AVL focus on software systems of autonomous driving systems. They developed a method for generating safety-critical simulation scenarios and an adaptive control procedure for compensating for internal errors. Additional can be found at the end of the message The future has already arrived.

By Christoph Pelzl The e-prop learning method developed at Graz University of Technology forms the basis for drastically more energy-efficient hardware implementations of Artificial Intelligence. The high energy consumption of artificial neural networks' learning activities is one of the biggest hurdles for the broad use of Artificial Intelligence (AI), especially in mobile applications.

By Birgit Baustädter She investigates black-box-systems, while he predicts the state of networked systems. Andrea Pferscher and Markus Tranninger are two of 11 young researchers in the TU Graz project "Dependable Things". Eleven young researchers are working as doctoral students or post-docs in the TU Graz lead project "Dependable Internet of Things in Adverse Environments" - "Dependable Things" for short.

By Christoph Pelzl New findings by researchers led by TU Graz computer scientists Wolfgang Maass and Robert Legenstein on neural information processing in the brain could enable more efficient AI methods. Additional can be found at the end of the message Specifically, the researchers have succeeded in mathematically modelling the emergence and interaction between so-called "assemblies".

Improving our understanding of genome structure and function is central to biology and medicine. My research group uses computational models to study the functional potential of each of the three billion pairs of chemical bases in the human genome. Ultimately, we are paving the way to designing personalized interventions against disease, which technological advancements are finally pushing toward reality.

By Birgit Baustädter Electronics-based systems have long since found their way into our everyday lives. Consciously in the form of new technical gadgets and unconsciously in the form of embedded systems. It is therefore impossible to imagine our familiar life without electronics-based systems. But, and here researchers are in agreement, they will continue to shape our environment in the future as the basis for many innovative developments.

Software LipidCreator enables researchers to characterise 60 lipid classes in cells with mass spectrometry Researchers increasingly aim at utilising the manifold functions of lipids in our bodies, e.g. as blood fats or in blood coagulation, to better understand and predict diseases. An international team around Robert Ahrends at the Faculty of Chemistry of the University of Vienna now presented a groundbreaking tool for efficient lipid analysis in the journal "Nature Communications".
