Seems like... so long ago...
ChatGPT is mind blowing, no matter what, that’s my humble opinion. Many of my colleagues for whom I have the utmost respect make fun of it, I’m inclined to tell you: you are playing a bit the referee 2 attitude.
So @NatureComms has highlighted our research home @IFISC_mallorca as an institutional model for interdisciplinary science! Congrats @MaxiSanMiguel for your vision, @EmilioHerGar for keeping the momentum and kudos all at IFISC. And thanks Apostolos Argyris for leading this!
🚀 Cross-disciplinary research is shaping the future! Discover how IFISC has become a global model, breaking silos and fostering innovation in complex systems. 🌐 Read more in @NatureComms: nature.com/articles/s4146… #ComplexSystems #ScienceInnovation #CrossDisciplinarity

🚨New preprint !! Interpreting the training process of a neural network as a temporal network trajectory, we found a regime where such trajectory becomes chaotic. Rather than a nuisance, such chaotic mixing boosts training! w/ P. Jiménez, @miguelcsoriano arxiv.org/abs/2506.08523

🆕 Preprint on the use of Machine Learning tools (deep reinforcement learning + transfer learning) for aerodynamic optimization !! w/ David Ramos, Gonzalo Rubio & Eusebio Valero arxiv.org/pdf/2505.02634
🚨 Our paper (with @wetuad and @tobiasgalla) is out now in Chaos as an Editor's Pick! We use pseudo-distances to characterize the dynamics of unlabeled networks... pubs.aip.org/aip/cha/articl…

This has now published in Expert Systems With Applications: shorturl.at/Olfig Great industry-academia collaboration @EsAirbus @aeroespacialUPM @esa @IFISC_mallorca
New preprint on a very practical roadmap: how to make and implement a thorough statistical validation pipeline of a machine learning solution in a real, industrial (aeronautical) use case. Great collaboration with @EsAirbus and @aeroespacialUPM arxiv.org/abs/2411.02075
We have looked at how 🧠evolves in graph space. We found that their network trajectories characterize well aging and brain pathologies. Details 👇

Hiring a postdoc in higher-order social dynamics: we will be doing models AND experiments (!) 36k/year renewable up to 3 yrs. In Barcelona, of course ;) Please RT! upf.edu/web/wssc/postd…
Today, we are publishing the first-ever International AI Safety Report, backed by 30 countries and the OECD, UN, and EU. It summarises the state of the science on AI capabilities and risks, and how to mitigate those risks. 🧵 Link to full Report: assets.publishing.service.gov.uk/media/679a0c48… 1/16
How to describe the dynamical properties of networks *with no labels* that change over time ? 🆕 preprint (with @_CaligiuriLisa_ @tobiasgalla ) arxiv.org/abs/2412.14864
Characterising the dynamics of unlabelled temporal networks (with @_CaligiuriLisa_ @wetuad) arxiv.org/abs/2412.14864 We use graph invariants to characterise time series of unlabelled networks, focusing on autocorrelation functions & sensitivity to initial conditions. We show >>>
🚨 New preprint out! We build **scalar** time series embeddings of temporal networks ! The key enabling insight : the relevant feature of each network snapshot... is just its distance to every other snapshot! Work w/ FJ Marín, N. Masuda, @vdbatman arxiv.org/abs/2412.02715
