Electrical Engineering and Systems Science > Signal Processing
Multiobject tracking using measurements from ar- rays of wireless sensors is a key task in applications ranging from autonomous navigation to public safety. Many existing methods compress raw complex-valued signals into detections or intensity maps during preprocessing, thereby discarding poten- tially relevant information about the objects and the propagation environment.
Electrical Engineering and Systems Science > Signal Processing
Multiobject tracking (MOT) is a fundamental capability in autonomous navigation, radar and sonar systems, as well as 6G integrated sensing-and-communication (ISAC) networks. In this paper, we propose a neural-enhanced track-before-detect (TkBD) framework that operates directly on complex-valued raw signals and learns a latent representation of unmodeled propagation effects during runtime.
Q&A: Expert says people often confuse behavior with intention with AI
Credit: Ketut Subiyanto from Pexels Recent safety tests have shown advanced AI systems making misleading statements, concealing information or attempting to prevent their own shutdown. Such findings regularly generate headlines. But what do they actually mean? Do they really point to a form of deception or self-preservation in AI systems? Or are humans too quick to interpret the behavior of language models through a human lens?
Apertus partners with Proton's Lumo AI assistant
Swiss technology company Proton, which specializes in privacy-focused services, and the research team behind the fully open language model Apertus are partnering to advance open and sovereign AI in Switzerland and Europe. Proton is integrating Apertus 1.5 into its AI assistant, Lumo, making it an available option to tens of millions of users and sharing their feedback with the Apertus team to help improve the model.
Computer Science > Machine Learning
Joint source localization and geoacoustic inversion requires optimizing an objective built from an expensive normal mode propagation model. Bayesian optimization (BO) with a Gaussian process (GP) surrogate can obtain accurate parameter estimates within a limited number of forward model evaluations, but its performance depends on the choice of kernel family.
How randomness tames vast network problems
The art of simplification: just as a painter reduces a subject to its essentials, Rasmus Kyng and his team simplify complex networks without losing the information that matters. Credit: Stephan Lütolf Networks are everywhere. They connect computers across the internet, carry electricity through power grids and represent transport routes for moving people and goods. Yet many problems that appear to have nothing to do with networks can also be represented and solved as networks.
Collaborative drawing offers new insights into how strangers become friends
Three examples of collaborative drawings (three self-portraits among the many wide-ranging motifs). Participants could draw anything they chose—the motifs of drawings were never specified by the researchers, to allow maximal creativity. The researchers chose drawing as the collaborative activity because it is also frequently used in practice in intergenerational social programs. Credit: Social Brain Sciences Lab The closer two people grow, the more alike their brains work—or so the assumption goes.
Quantum Computer Stores Data in Vibrations Like Notes on a Guitar
The new quantum chip developed by ETH Zurich physicist Yiwen Chu contains so-called mechanical resonators, tiny components that begin to vibrate when storing information. The chip is approximately 7.5 millimeters long, 2.5 millimeters wide, and 1 millimeter high. This makes it roughly as wide as a small fingernail.

New miniature laboratories are ensuring that AI doesn't make mistakes
Anyone who develops an AI solution sometimes goes on a journey into the unknown. At least at the beginning, researchers and designers do not always know whether their algorithms and AI models will work as expected or whether the AI will ultimately make mistakes. Sometimes, AI applications that work well in theory perform poorly under real-life conditions. In order to gain the trust of users, however, an AI should work reliably and correctly.

PKD3 localizes to late endosomes to maintain Rab7-dependent endolysosomal homeostasis
Abstract Protein kinase D3 (PKD3) is an important regulator of triple-negative breast cancer (TNBC) progression by promoting invasion, proliferation, and stem cell maintenance. However, the mechanism underlying these cellular functions has remained unclear. Here, we report that endogenous PKD3 localizes to Rab7/Lamp1-positive vesicles in MDA-MB-231 cells cultured on stiff matrices. Notably, upon PKD3 depletion the size of Rab7-positive vesicles is smaller.

Researchers explain how cities can implement environmentally sustainable densification
The housing situation in Swiss cities and towns is currently the subject of intensive debate in politics and the media. Housing and densification is a key topic for spatial and urban planners—because, ultimately, they are tasked with implementing compact, inward settlement development that is mandated by the Swiss Spatial Planning Act since 2014.
What can cities do to promote acceptance of densification?
Swiss cities are more likely to accept densification when densification projects provide affordable housing and green spaces compared to densification that is implemented through reduced regulations for housing construction. By prioritizing a socio-ecological densification, extensive planning procedures and delays might be minimized. The housing situation in Swiss cities and towns is currently the subject of intensive debate in politics and the media.
Designed for bold visions
The idea of ETH Zurich establishing a Department of Biosystems in Basel once seemed unachievable.

How ETH knowledge and local expertise are helping the reconstruction of Ukraine
Two years ago, Russia launched its war of aggression against Ukraine. One direct consequence of the conflict is the destruction of buildings and infrastructure. Now an exhibition in the ETH Main Building entitled "ETH with Ukraine" is showing how buildings, facilities and the environment in Ukraine can be protected or restored. Not only is the war causing immeasurable human suffering, it is also destroying vast swathes of buildings, facilities and infrastructure.

Improving patient safety
On the road to recovery, patients come into contact with clinicians from a whole range of disciplines. The importance of targeted collaboration between these disciplines is something medical students learn early on at ETH Zurich. When illness strikes, people generally turn to a doctor for help. He or she prescribes the appropriate medicine and determines whether any other treatment might be necessary. The relationship between patient and doctor therefore plays a major role in recovery.
How Zurich has to change its roads to have more e-bikes than cars Original
What would the streets look like if a city took half its traffic space and gave it to cycling and e-biking? Would city dwellers use their bikes more often? Might the concept of an "E-Bike City" even be a way to help reduce transport-related CO2 emissions? Nine professorships at ETH Zurich and EPF Lausanne have been investigating these questions for a good year and a half. This research initiative is led by transport researcher Kay Axhausen, who is retiring in January 2024 (see box).
