Fun Papers

A Dialogue Among Aalto People

I would like to mix one of the coffee breaks with some fun conversations around some scientific/geeky stuff! I’d like to organize an informal recurring not-a-journal club in one of the fancy roof rooms at the CS department of Aalto University.

A fancy roof room at Aalto!

The idea is simply to gather together for a coffee break while someone gives a short, interesting talk on some subject that s/he is learning or working on such that anyone from any CS (or STEM) group can follow it, enjoy it, and finally say Aha! This is a Dialogue Among Aalto People program; the objective is to learn from each other. Why not?! We are from different backgrounds working in different groups, which means there are tons of learning and networking opportunities. Did I mention we’ll have fun with cardamom tea as well?! Oh, by the way, everyone from the School of Science is welcome!

I prefer afternoons and sessions of 30 min long. I prefer not to use advanced technologies and monstrosities of machines for presentations and mostly rely on storytelling methods in giving a scientific talk next to a board. Any topic is welcome as long as it is explained in a clear way. If you want to choose a paper, I would recommend oldies, but goldies first! Talking about a recent research article that you have not done is also a good candidate if you feel it can be a case of interest for the folks or if you can use it as an example to convey your message!

A Personal Motivation

My background is in Statistical Physics. I’m, by and large, interested in topics at the interface of physics and computer science. I study complex systems, and as a doctoral researcher, I model epidemics at the CS dept.! More specifically, I’m working on problems that are basically about phase transitions in networks. So, I have some stories about phase transitions to tell you! I’ve recently come to this paper, which is new and has a funny title:

Subjects: Statistical Mechanics, Disordered Systems and Neural Networks

So, for the first session, I can tell you about different phase transitions and use this paper as a funny example so that you remember what happened in that session.

I can also tell you about the shape of stories!

Any feedback or comment is welcome!

Let’s decide about its time. For example, what about every Wednesday of each month at 16:00? Tell me if you have any ideas, please. You can definitely text me on Telegram or email me.

A list of topics (suggestions)

Oldies but goldies: R. Penrose, The role of aesthetics in pure and applied mathematical research, 1974. Penrose tiling are aperiodic tilings obtained using typically 2 isosceles triangles with two types of edge labelings (so 4 types of triangles).

Different Faces of Entropy

  • There are at least three distinct ways to conceptualize entropy: entropy as an extensive thermodynamic quantity of physical systems (Clausius, Boltzmann, Gibbs), entropy as a measure for information production of ergodic sources (Shannon), and entropy as a means for statistical inference on multinomial processes (Jaynes maximum entropy principle). Even though these notions represent fundamentally different concepts, the functional form of the entropy for thermodynamic systems in equilibrium, for ergodic sources in information theory, and for independent sampling processes in statistical systems is degenerate, $H(p) = – \sum p_i \ln p_i$. For many complex systems, which are typically history-dependent, nonergodic, and nonmultinomial, this is no longer the case. [Ref]
