First Workshop of the Florence Center for Data Science

Hi, Nedoers,

this quick message is for advertising a workshop in Florence launching the Florence Center For Data Science, directed by prof. Mealli. You can find more information here.

Florence is near, even if Trenitalia may have given you a different perspective, thus participate since it is soopercool 🙂 By the way, viale Morgagni is pretty close to the Firenze Rifredi railway station, you can easily reach the conference venue on foot.

Cheers and stay tuNEDO!

I mean, Science is cool, but even Lampredotto is. Do not leave Florence without trying it!

TOFFEe workshop!

Dear Nedoers,

TOFFEe (TOols for Fighting FakEs) is a IMT PAI (Progetto di Attività Integrata, integrated research activity project), leaded by prof. Rocco De Nicola and including prof. Guido Caldarelli, prof. Irene Crimaldi, dr. Fabio Saracco and dr. Marinella Petrocchi (IIT, CNR, Pisa).

The TOFFEe crew is proud to invite the whole IMT community (but, above all, the Nedoers) to its first kick-off workshop, that will take place on Wednesday April 17 at 2 pm in the Cappella Guinigi.

The ambition of TOFFEe is to overcome important limitations of existing social platforms, which often dedicate little attention to trustworthy interaction among peers and to reliability of information. The aim of the project is to increase people’s confidence on the data they get and about who they follow, while minimizing the risk of false information and malicious actions.

TOFFEe will build on expertises in Computer Science for studying the effective paths of data over the net and their sources, Network Science for studying social connections, Sociology and Psychology for studying the dynamics leading to trust fakes, Probability and Statistics for analyzing the widespread of the fakes and their impact. Given the multidisciplinary nature of the proposal, many of the expertises present in the IMT School, well beyond the list of proposers, will be involved.

The (tentative) program has already changed since the official mail:

14:30 Rocco De Nicola, Guido Caldarelli (IMT School): Introduction 

15:10 Andrea Nicolai, Simona De Rosa (T6Ecosystems): SOMA: the European social Media Observatory on disinformation: strategies and plans to tackle fake news 

15:30 Break

15:40 Stefano Cresci (IIT, CNR, Pisa): Spotting content-polluting botnets in Twitter

16:00 Marinella Petrocchi (IIT, CNR): Better Safe Than Sorry: an Adversarial Approach to improve Social Bot Detection

16:20 Toffee Break

16:40 Alessandro Balestrucci (GSSI School of Advanced Studies, L’Aquila): The target audience of misinformation: Credulous human users

17:00 Carolina Becatti (IMT School): Collaboration and followership: a stochastic model for activities in social networks

17:20 Fabio Saracco (IMT School): The backbone of news consumption on social networks and the political debate on Twitter 

17:40 Rocco De Nicola (IMT School): Conclusions and farewell

 

You are welcome to participate, whether you are interested or not.

 

Cheers and stay tuNEDO,

Nedo

The TOFFEe logo is indeed pretty cool.

 

For A Few Conferences More

Nedo meets a colleague in a summer school

Hi, guys,

Nedo is still silent, but not for long. Even if it is going to be more “formal”, next week we are going to have a network workshop, more details are going to appear soon. In the meanwhile, Nedo continues advertising conferences:

 

CRITICAL AND COLLECTIVE EFFECTS IN GRAPHS AND NETWORKS – 2019: Les Houches, May 6-10

CBNA Summer School in Social Network analysis 2019: Greenwich, June 3-14

Complexity72h, Lucca, of course 🙂 17-21 June

Lipari School on Computational Complex and Social Systems 2019:  July 19-25

Advances in Complex Systems: From Ecology to Economics 2019: Lake Como School of Advanced Studies, July 22-26

Mediterranean School of Complex Networks: August 31- September 6

CCS 2019, Singapore: September 30-October 4

Have fun and stay tuNEDO!

Conference advertisement!

Dear Nedoers,

the Nedo fire rests under the ashes, but it will come up again soon. Not as Nedo, but as a huge list of (more formal) seminars by the Networks group. As always, stay tuNEDO!

In the meantime, Nedo advertises the first Regional Conference in Complex Systems in Trento. Here you can find the official website: as you can see there are really nice invited speakers.

Stay tuNEDO for the next events,

cheers!

Kids time: Matteo Bruno!

Kids time again! Matteo Bruno spontaneously decided to present his last paper (at moment available on arxiv here), Colombian export capabilities: building the firms-products network. We are going to meet in classroom 1 on Friday 5th at 12.30.

Cheers

Juan Ignacio Perotti @IMT

It is a great pleasure for the Nedo board to announce the following talk.

Juan Ignacio Perotti, formerly on board on the NETWORKS unit, is presenting the talk “Thermodynamics of the Minimum Description Length on Community Detection“, tomorrow, 2nd of October at 18 in classroom 1.

Abstract: In this talk I will introduce the Boltzmannian MDL (BMDL), a framework we have developed for statistical modeling [1]. Firstly, I will present the concept of universal codes and how they are related to different frameworks for statistical modeling. In particular, I will introduce the Refined MDL (RMDL), which is the “most effective” universal code, and which is the basis from where we develop ours [2]. Secondly, I will introduce the BMDL and how it should be used for model selection. Thirdly, I will reintroduce the BMLD; this time to address the statistical significance of the model selections. Fourthly and finally, I will show and example of its application on the problem of community detection in complex networks [3]. In particular, I will show how we can derive from the BMDL: i) Girvan-Newman modularity [4] and ii) Zhang-Moore method and criteria for community detection [5].

2 of 2: the Nedo champion is here to stay

At CCS 2018 in Thessaloniki, the IMT troop observed a rare bold demonstration of power. Already being the champion in charge, after challenging her mentor Tiziano in IMT, during the Complexity72h, Federica demonstrated that the Nedo champion is here to stay. In her first contribution at the conference, she showed a slide with the Nedo can.

Actually, there is no reason for the Nedo can to appear in this slide. That’s the difference between a good player and a prodigy.

Not satisfied for being confirmed as the Nedo champion, she decide to reiterate her position the following day.

If Nedo can had no sense to be there yesterday, today it is ok too!

With the result of this morning, she scored the longest series of confirmations in the history of the Nedo award. Challengers are warned.

A great day for Nedo Award

It is a big pleasure for Nedo to announce a great activity on Nedo award: during the Complexity 72h, held in IMT two great events happens. First, Tiziano, as part of the organisation,  presented himself with this slide which is a sort of meta-Nedo: a shot of himself presenting a slide with the Nedo can (this one).

You probably cannot see it: Tiziano presenting a slide with Tiziano presenting a slide with Nedo.

Then, the disciple overcame the teacher: few minutes later Federica Parisi (the actual owner of the award) presented the following slide:

It’s small, but it’s there!

So, congratulations to the new holder of the Nedo Award!

Rossana on top of CCS’16

When I prepare a seminar, […] I always think about NEDO.
–Rossana Mastrandrea (acceptance speech for the CMPLXSSTMS award)

NEDO is very proud to greet Rossana for the award won for the best presentation at CCS’16 in Amsterdam!  More photos can be found here.

Anyway, Ross have not offer yet any drinks to her colleagues to celebrate the award and it usually brings bad luck…
