IRMA: Machine learning-based harmonization of 18F-FDG PET brain scans in multi-center studies
by Michael Biehl 19 Feb '25

19 Feb '25

Our paper "IRMA: Machine learning-based harmonization of 18F-FDG PET brain scans in multi-center studies" by Sofie Lövdal et al. has been published in the European Journal of Nuclear Medicine and Molecular Imaging and is available online (open access): https://link.springer.com/article/10.1007/s00259-025-07114-4 In this work we apply interpretable machine learning systems for the analysis of 18-FDG PET brain scans from different medical centers. We show that the center origin of healthy control brain images acquired with different scanners/protocols can be identified with high confidence. Consequently, machine learning models trained with data from different scanners may be heavily impacted by this bias when applied to a clinically relevant problem, e.g. the differential diagnosis of neurodegenerative disorders. We propose IRMA (Iterated Relevance Matrix Analysis) as a recursive method to learn and disregard bias in PET feature vectors.

[Meeting] CRNS Talk Series - Live Talk by Dr. Yumi Iwashita - NASA JPL, USA
by Amir Aly 18 Feb '25

18 Feb '25

Dear All * *Apologies for cross-posting** The* Center for Robotics and Neural Systems* (CRNS) and *UK-Ireland IEEE RAS Chapter* are pleased to announce the talk of *Dr. Yumi Iwashita* from *NASA JPL, USA* on Wednesday, *February 26th *from *3:30 PM* to *5:00 PM* (*London time*) over *Zoom*. *Thank you for forwarding the invitation to any of your colleagues who might be interested*. >> *Events*: The CRNS talk series will cover a wide range of topics including Social and Cognitive Robotics, Computational Neuroscience, Developmental Psychology, Computational Linguistics, Cognitive Vision, AI and Machine Learning, and healthcare. More details are available here: https://www.plymouth.ac.uk/research/robotics-neural-systems/whats-on <https://eur03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.plymo…> >> *Link for the next event (**No Registration is Required**)*: Join Zoom Meeting *https://plymouth.zoom.us/j/95753314935?pwd=B9cuV9Dj6MWkhgrWEZrGsVz9brL21Q.1&from=addon <https://plymouth.zoom.us/j/95753314935?pwd=B9cuV9Dj6MWkhgrWEZrGsVz9brL21Q.1…>* >> *Title of the talk: **Exploring Moons: Preparing for Future Missions to Europa and the Moon* *Abstract*: Each planet has one or more moons, many of which hold immense potential for unlocking fundamental questions about the origins of life. Among the numerous moons in our solar system, Jupiter’s Europa, Earth’s Moon, and Saturn’s Enceladus are of particular scientific interest. NASA’s Jet Propulsion Laboratory (JPL) has undertaken several projects focused on these celestial bodies. In this talk, I will introduce two key projects related to Europa and the Moon. The first project, the Europa Lander Mission Concept, faces significant challenges, including a highly limited operational lifetime, constrained energy supply, intermittent communication with prolonged blackouts, and hazardous environmental conditions. Moreover, its extreme distance from Earth prevents reliance on real-time human control. To address these constraints, we developed an autonomous software prototype to test and validate planning and execution strategies for science-driven missions with minimal human intervention. Additionally, we demonstrated autonomous sampling techniques at Matanuska Glacier, Alaska. The second project, LuNaMaps, focuses on autonomous lunar landing. Successful planetary landings require precise localization with respect to the targeted site. However, landing on the Moon presents unique challenges, including insufficient global high-resolution data, the need to validate existing datasets, and extreme illumination conditions—especially at the poles. To address these issues, we have developed methodologies for generating high-quality Digital Elevation Maps (DEMs) and tools to evaluate their accuracy and reliability, supporting future lunar exploration missions. >> If you have any questions, please don't hesitate to contact me, Regards -------------------------------------------- *Dr. Amir Aly*, PhD, FHEA, SIEEE Lecturer in Artificial Intelligence and Robotics Programme Manager of Artificial Intelligence UK and Ireland IEEE RAS Chapter Vice Chair Director of the Centre for Robotics and Neural Systems (CRNS) School of Engineering, Computing, and Mathematics Room A307 Portland Square, Drake Circus, PL4 8AA University of Plymouth, UK

Using chronic calcium imaging in mouse auditory cortex, we show that during this representational drift signal correlations predict future noise correlations, suggesting that stimulus-driven co-activation strengthens effective connectivity via Hebbian-like plasticity. Linear network models reveal that these temporal dependencies between signal and noise correlations emerge only when Hebbian learning balances stochastic synaptic changes, preventing functional degradation. Our findings highlight how ongoing input-driven plasticity stabilizes neural representations amidst inherent synaptic variability. *About VVTNS : Launched as the World Wide Theoretical Neuroscience Seminar (WWTNS) in November 2020 and renamed in homage to Carl van Vreeswijk in Memoriam (April 20, 2022), Speakers have the occasion to talk about theoretical aspects of their work which cannot be discussed in a setting where the majority of the audience consists of experimentalists.

[Workshop in Mallorca] Embracing Complexity
by RUBÉN HERZOG 14 Feb '25

14 Feb '25

We are pleased to invite you to the Workshop titled "Embracing Complexity: Principled and Practical Approaches to Emergence". The workshop is scheduled for June 23-27 2025 at the Institute for Cross-Disciplinary Physics and Complex Systems (IFISC in Spanish) in Palma de Mallorca, Spain ( https://ifisc.uib-csic.es/en/) ABOUT THE WORKSHOP This workshop will offer a comprehensive and interdisciplinary perspective on the applications of emergence in examining various real-world systems, including its use in understanding high-order interactions and complexity across diverse biological and ecological scales. With an emphasis on the micro-to-macro relations between cells, humans, and ecology, we aim to present emergence both as a practical tool and a principled approach. The mornings will be devoted to theory-driven presentations that draw from recent operational advances in capturing emergent phenomena, while the afternoons will feature hands-on sessions tailored for practical implementation of these topics. Something we are most thrilled about will be a coordinated outdoor excursion during the week to unwind and visit the island. This is not all, we also plan to have an immersive installation centred on exploring a collective experience of emergence with the voluntary participation of all the attendees. We hope you will also be pleased to join! REGISTRATION All applications should submit an abstract, which will be the key element for selection. After selection, participants will be asked to pay a fee of 400€, which will cover 5 nights (from the 22nd to the 26th of June) at the residency of the Universidad de las Islas Baleares, breakfast, lunch, coffee breaks and the excursion. SUBMISSION DEADLINE 14 of March of 2025. Selection will be informed by the end of April of 2025. Abstract submission here <https://forms.gle/eQhWYyC3mjd6EhYC9>.
