Projects marks - minor correction

11 janeiro 2017, 18:05 • Francisco Correia dos Santos

Dear RC students,


I have noticed a small mistake on the marks previously published regarding your projects. I sincerely apologise for this. The changes are minimal. Nonetheless, I would like to raise your attention to this. I apologise once again for not noticing this issue before. Thank you for your understanding.

Best wishes, Francisco.

PS: If you need a hand during this week regarding next week's exam, please check my previous post. Next week, I will be also available on Monday and Tuesday (both at Alameda and Taguspark). This friday, I will post some special office hours, after aggregating your preferences. Hope it helps.

Exam, Jan 18

Dear RC students,

All my best wishes for 2017!! 
As you noticed (see here for details), Alexandre and I were delighted by your projects. Congratulations to all!! The next challenge will be to keep the same level at the exam. 
The enrollment for the 1st exam (18 Jan) remains open for those interested. Please let me know if I can be of any help. The exam will closely follow the discussions we had during our lectures & our problem sets. 
Tomorrow (Tuesday, Jan 10), I will be available from 14h30 until 16h at “Gabinete 1” (2nd floor, DEI, Alameda, next to the central services of the Department of Computer Science and Engineering). You may also find me at the same room this Thursday (Jan 12, 11h30). On Friday (Jan 13) I will be available at Taguspark. 

Hope it helps!

Best, Francisco.

Network Science Workshop (day 2)

10 dezembro 2016, 12:24 • Francisco Correia dos Santos

Dear RC students,
Last Friday we had our first day of presentations, and the results were great!! Many thanks to all the speakers and those that took the time to step by. We had new insights on the dynamics of cooperation, fairness, the role of groups, pathological behaviors, wealth inequality, biodiversity and tax paying. We had 4 new models on disease spreading, including spreading of Zika in Portugal, analysis of the role of risk groups and their vaccination, the complex interplay between awareness and epidemic spreading, and smart ways to compute epidemic thresholds. Finally, we were pleased to hear an application of network science to film and literary studies, from star wars to Marvel’s graphic novels, including how ties among characters may sway imdb scores, and why Captain America plays a central role in the world’s future.
This monday (12 Dec), we will certainly continue to use science to have a nice time. We will start with new provocative analysis of financial networks, language networks, and authorship attribution through networks of words. We will learn how to approximate the Internet with traceroute and what one should know when doing so. We will also learn how we can use Heat Kernel as a ranking method, learn new sophisticated algorithms to compress graphs, discuss how to parallelize computations on graphs, and get to know about ranking methods for local partitioning. We will also discuss how racial segregation may emerge in cities, and how rumors spread in complex social structures. We discuss the intricacies of voting systems, and how reputations can change our tendency to cooperate. Finally, we will discover that the slope of power-law degree distributions may tune epidemic outbreaks and assess the robustness of airline networks against terrorist attacks. We will have plenty of food for thought!
Please don’t forget that the seminars will be held on Amphitheatre PA3, "Pavilhão de Matemática" (see building 24 here), and start at 14h.
Here’s the detailed program:

December 12, Monday (amphitheatre PA3, "Pavilhão de Matemática")

  • 14:00 "Beyond a Reasonable Doubt”: Temporal dynamics of financial networks (Group 17)
  • 14:30 On the structure of language networks (Group 13)
  • 14:50 Comparing function word adjacency networks for authorship attribution (Group 14)
  • 15:10 Algorithms Behind Web Search (Group 25)
  • 15:40 ParaGRAPH framework and efficient immunization without global knowledge (Group 20)
  • 16:00 Approximating the Internet graph by sampling with traceroute (Group 15)
  • 16:20 Layered Label Propagation in the Webgraph (Group 10)
    Break (15 min)
  • 16:55 Rumor spreading in structured populations (Group 19)
  • 17:15 Evolution of indirect reciprocity by image scoring (Group 5)
  • 17:35 Schelling’s Model of Segregation (Group 6)
  • 17:55 Voter model in networks (Group 4)
  • 18:15 Robustness of airline networks (Group 8)
  • 18:35 Expected epidemic threshold in Scale-Free networks as a function of the exponent of the degree distribution (Group 12)
  • 18:55 On the use of ranking for local partitioning of graphs (Group 27).

This will be our last class before Christmas break, and a perfect way to finish. In January we will be available for anything you need, particularly in what concerns the preparation for the exam (more news on this later). 
Hope to see you all next monday and thank you once again for your great effort and enthusiasm.

Best,Francisco & Alexandre
