TURING TALK – “Complex Network Analysis”

Filed under: Campus,Events,Turing Talks — csa2010 @ 9:22 am

24th September, 2011: Continuing with the tradition of  Turing Talks, which is a CSA organised lecture series, Ajitesh Srivastava, the Mr. Turing of the day, presented an illuminating yet exciting talk on Complex Network Analysis. The evening saw a descent turnout of  approximately 60 keen participants . With focus on the mathematical modelling  of social networks,he paid emphasis on acquainting the audience with the basics of the same before delving deeper.

The later part of the evening was mostly dedicated to,

  • Modelling of a subset of the BITSian friendship network and determining the various mathematical parameters associated.
  • Plotting of the twitter growth model and comparing with the actual data, thus paving way for show stopper,
  • The Power Law which practically dominates the growth pattern of most social and collaboration networks.

The speaker managed to keep the audience interested by picking up interesting demonstrations of  Power Law in collaboration networks like the Erdos’ number and the Bacon number, seemingly flawed but true instances !

The event wrapped up with a round of interesting queries, thus providing an intellect invoking end to the lecture.Many thanks to Mr. Turing, Ajitesh and lets hope to see the Turing Talks get bigger and better.

Cheers!

P.S I have share the presentation slides below

MINDTURNER 4.0

Filed under: Events — csa2010 @ 4:38 am

31th August, 2011: The end of August saw the initiation of CSA events with Mindturner completing its fourth successful year.With a decent assemblage  of quizzing enthusiasts, the event was good to go by 5:30 pm.

At the very outset,  the audience was briefed  on the rules governing the game; which basically were :

  • an upper limit of 3 members in a team
  • higher weight-age to starred questions and,
  • the supremacy of the quiz-master of course.

The quiz began with relatively simpler questions, soon to delve into trickier and wit demanding ones later in the evening. Brainstorming to say, was clearly in the air with frowned minds attempting to unveil the answers.The smartness of the audience was evident from the very fact that hints to certain prechosen  questions were vehemently discouraged by certain teams.

Internet history and less known significant events were the ruling themes of the event.Certain genre of successful questions of the former Minturners  like ‘Photo Connect’  were continued while some new patterns viz. xkcd’s and dooodles were experimented with.With questions reaching an  exhaustion point, the unmistakable determination to win was clearly portrayed on  the participants’ faces.

The event concluded with a moderately famous xkcd question which had  a  definitely  illustrious answer, thus not posing a significant disadvantage to the ones new to it.This marked an end to the very first CSA event of the year and yes a promising end, that is.Wishing greater peaks of success to Mindturner 5 and the other events to follow. ‘Stay hungry, stay foolish’ and watch everything fall into place!
