🚨new preprint !! How to describe, forecast or control the dynamics of temporal networks? A possible approach includes using fluid mechanical data-driven tools such as #POD and #DMD. Preprint: arxiv.org/abs/2509.03135

🚨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.bsky.social arxiv.org/abs/2506.08523

Leveraging chaos in the training of artificial neural networks
Traditional algorithms to optimize artificial neural networks when confronted with a supervised learning task are usually exploitation-type relaxational dynamics such as gradient descent (GD). Here, w...

🚨 Just published !! How to extract a *scalar time series* that accurately captures the dynamics of a whole temporal network ? #netsci2025 too bad I missed you. Great Collab w/ Lluís Arola, Naoki Masuda and F. Javier Marín Open access --> www.sciencedirect.com/science/arti...

New Study Out Now! We investigated how deep brain stimulation (DBS) of the nucleus accumbens (NAc) affects memory. www.nature.com/npp/ Title: NAc-DBS selectively enhances memory updating without effect on retrieval 👇 THREAD 👇

We have looked at how 🧠evolves in graph space. We found that their network trajectories characterize well aging and brain pathologies. Details 👇

🚨 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, L. Arola-Fernández arxiv.org/abs/2412.02715

Hi Bluesky! My first skytweet is to reflect on how more is different when individual AIs come together arxiv.org/abs/2310.12802 #complexsystems #emergence #machinelearning
