Ayer tuvimos el honor de celebrar el acto de entrega de la I edición de los Premios DIFENSC de tesis doctorales. ✨❄️

¡Enhorabuena de nuevo a los ganadores Guillermo Barrios Morales y Jorge Tabanera Bravo! 🏅

Gracias a la fundación Sicómoro por hacerlo posible.

🎤 We’re thrilled to announce our next #WWCS26 speaker: Carmen Cabrera, Lecturer in Geographic Data Science at the University of Liverpool.
Camren's research focuses on human mobility patterns across spatiotemporal scales and population groups. We look forward to meeting her at Mallorca ❄️🌍

This week I travelled to the island of Ons in Galicia. An amazing natural reserve in the middle of the Atlantic. ⛵🗺️

That said, my main reference when thinking about communities is precisely your work on descriptive vs inferential approaches that you mention, so I will probably agree with you on most aspects :)

But at the same time, I think it's nice to keep in mind that there are situations where looking at disconnected components as a extreme case of communities can make sense, especially if the objective of the study is not to analyze data.

I completely agree, mixing two conceptualizations of community can lead to problems, because minimizing cut-sets and maximizing likelihoods are based on very different assumptions.

To be clear, I agree that interpreting community detection as a maximum-likelihood problem is a more powerful approach to understand complex datasets. My point is that, from a mathematical (not statistical) point of view, the other vision can be insightful too.

In fact, I would say the pure-math approach to communities tends to understand them as "almost disconnected" regions (partitions with a small cut-set), and this perspective has led to nice results (for example the Cheeger inequalities, the spectral clustering algorithms, perturbative methods, etc).

I think the interpretation of communities as network partitions with a small cut-set is useful in certain areas. Ofc, claiming that this conceptualization of community is statistically meaningful is problematic, but as a descriptive concept I think it's ok.

It's so frustrating that symmetric graphs always have degenerate spectra. Why do I have to choose between graphs that look nice and graphs that behave properly? I want both :(

Signed networks to understand social systems by Sofia Teixeira

BRAN Lab Bridging Minds, Behavior, and Society through Network Science

It’s happening.
BRAN Lab is here, my first research group.

We explore how and why we connect (and disconnect), using network science, signed networks, ML, and cognitive modeling: from minds to systems, humans to AI, mental health to epidemic prevention.

After one night in Palma, I am already missing the temperatures in Madrid.

Ojalá un debate entre @lavacaesferica.bsky.social, @juanjosemillas.bsky.social y Arsuaga a raíz de la frase "si no conocemos las interacciones que ocurren en su interior, tampoco seremos capaces de predecir el comportamiento del sistema".

Leyendo a Millás y Arsuaga, me encuentro que las ideas de sistemas complejos han llegado hasta la arqueología y la literatura. Eso sí, la definición de Arsuaga se deja fuera aspectos como la heterogeneidad de las interacciones, la existencia de parámetros irrelevantes en comportamientos macro, etc

Our next keynote at #Fises2025 is by José Cuesta on entropy and evolutionary dynamics: where Darwin meets Boltzmann. #StatisticalPhysics #EvolutionaryDynamics

We end the second day of #fises2025 with three contributed talks by Pablo Moreno-Spiegelberg, José Vilar, and Alex Giménez Romero, and an invited talk by Saúl Ares about the physics of bacterial conjugación.

Good morning from Day 2 of #Fises2025! We begin with a keynote by Cristina Masoller: “Nonlinear data analysis tools for complex systems research”. 🔍📊 #NonlinearDynamics #ComplexSystems

Happy to present my latest article in @physreve.bsky.social
! In this paper, I show that the Voter Model can predict individual opinions in a large, heterogeneous online population.

Today I broke my record of amount of paperwork to get a conference trip refunded. The previous record was an astonishing 14 PDFs, but this was shattered by today's 17 PDFs 🤯🎊. Congratulations to all the regulations and normatives that worked so hard to achieve this amazing record. 🎉🎉

Reviewing a submitted research paper and asessing some student projects. The students' reports are of better quality than the research paper. My lecturer side is so proud of the students, but my researcher side is not so happy hahaha

Y por cierto, si se usa un examen para establecer un ránking de alumnos, que es lo que hace Selectividad, poner exámenes excesivamente fáciles hace que el ranking no refleje la capacidad de los estudiantes sino fluctuaciones/despistes en el día del examen...

Si un ingeniero ha tenido problemas para resolver el examen de mates de Selectividad, honestamente eso dice más del ingeniero que del examen 😶😶

Today at #NetSci2025, I will talk in the signed networks parallel session about... Signed networks!
👉16:30 | “Signed graphs in data sciences via communicability geometry” 💥
There will be a cool mix of networks, geometry, matrix theory, and data analysis :)

And this is was a wrap of the FRIENDS (signet-friends.github.io) satellite in its first edition at @netsciconf.bsky.social ! 60+ attended and engaged with the amazing lineup of speakers.
