hello!welcome to the workshop!

aimed at◦anyone interested to know about

current advances in math and CS

◦anyone who wants to get a taste of what happens in the math and CS world

prereqssome algebra might be helpful

if no algebra background, you can still follow through the discussion

preferably, a laptop with you to try out some stuff later

a bit about myselfnazmus saquib (sakib)

undergraduate in {physics, computer science and mathematics}

MS in computational mathematics

research student in scientific computing and imaging institute

previous experience in robotics, particle physics and cognitive science

chaos theory!butterfly effect

◦coined by Lorenz – an American Mathematician and Meteorologist

◦small perturbations can cause big changes!

◦how small, and how big?

◦a hypothetical butterfly

◦pendulum example

butterfly effect

double pendulum

philosophical implicationswhat causes big changes?

rumor spreading in a society

our actions can have bigger effects than we think

why do we care?weather forecast!

fractalsstart with a seed

change some properties

repeat!

digital humanitieswhat can we do with numbers?

viewing numbers can be useful

graphs, charts, images

data miningnatural language processing

◦sentiment Analysis convert emotional sentences to numbers!

“I really hated reading the fifth chapter” {0, 2*, -4, 1, 0, 0, 0} => {-8, +1}, assigned

to fifth chapter.

intelligent deduction – score dictionary of emotion words.

sentiment analysis in literature?

Sentiment evolution in “Montezumma’s Daughter” – Henry Rider Haggard

Painting a Novel

visualization techniquesExample work: Hadith text comparison

thanks for showing up!

next time, some hands-on mathematics and computing!
