Matematički institut SANU organizuje zajednički sastanak Odeljenja za matematiku i Odeljenja za mehaniku, u utorak, 31.8. u 18h u sali 2 SANU.
Predavač: prof. Oskar Mencer, Imperial College London
Naziv predavanja: Vertical Acceleration: From Algorithms to Logic Gates
Abstract. Huge growth in the complexity of science over the past decade has driven the need for ever more computationally demanding mathematical models. This has in turn led to massive growth in data center compute capacity, and consequently power and cooling requirements. We report the real-world results from Maxeler Technologies to improve the price-performance and just raw speed for financial and seismic computations by using custom computing machines. The key to our acceleration approach is the vertical acceleration of key pieces of the algorithms, including the bit level, arithmetic level, architecture level, and algorithm level.

Naslov predavanja:
Structured Regression by Continuous Conditional Random Fields and Multiple Noisy Oracles
ABSTRACT:
We will first describe and evaluate our new kind of probabilistic model for structured regression called continuous conditional random fields (CCRF) that uses multiple non-structured predictors as its features. These features are constructed such that the result is a Gaussian predictor where learning is reduced to convex optimization leading to a global solution for a set of parameters while inference is conveniently conducted through matrix computation.
Then, we will present a new Bayesian approach that learns a regression model from data with noisy labels obtained by multiple oracles. Our method provides a closed form solution for model parameters and in our experiments was consistently more accurate than a model trained with averaged estimates from multiple oracles as labels.
Presented results are obtained in collaboration with Y. Guo, V. Ouzienko, V. Radosavljevic, K. Ristovski and S. Vucetic at Temple University. Both articles will appear at the Proc. 19th European Conf. on Artificial Intelligence, Lisbon, Portugal, Aug. 2010.

Detaljnije: Sa zadovoljstvom Vas obaveštavamo da je studentski tim Matematičkog fakulteta u sastavu:
Marija Jelić, Marijana Smailagić, Igor Uljarević i Raca Todosijević
pod iskusnim rukovodstvom prof. Đorđa Dugošije osvojio 4 srebrne medalje na prestižnom međunarodnom takmičenju iz matematike IMC 2010 u Blagoevgradu, Bugarska (International Mathematics Competition for University Students 2010 http://www.imc-math.org.uk/).
Čestitamo takmičarima i svima koji su pomogli i doprineli velikom uspehu. Planiramo da krajem avgusta ili početkom septembra organizujemo prijem povodom postignutih rezultata naših studenata.
U ime dekanskog kolegijuma Matematičkog fakulteta,
prof dr Miodrag Mateljević

Detaljnije: Naredni sastanak CGTA seminara održaće se u utorak, 13.07.2010, od 18-20h, na Matematičkom fakultetu, IV sprat (BIM sala)
Predavač: Ph.D., Mathematics, Princeton University Professor of Mathematics, Brandeis University
Naziv predavanja: An introduction to higher torsion invariants of smooth bundles and related topics.
Predavanje je zamišljeno kao veoma interaktivno, tj. prilika da se postave pitanja o nekim od centralnih tema topologije, geometrije i algebre iz oblasti ekspertize prof. Iguse.
Drugo predavanje tokom svog boravka Beogradu prof Igusa će održati u okviru Odeljenja za matematiku, u petak, 16.07.2010. u 14h (sala 2, SANU)
Naziv predavanja: THE CATEGORY OF REGULAR MATROIDS
Abstract: In this talk I will explain the definitions of categories of graphs and matroids, review recent results about the homotopy type of categories of graphs and its relationship to the cohomology of the mapping class group of a punctured surface and show how these are related to the category of regular matroids and their generalizations. I will explain the purpose of this theory and some preliminary results, most of which are in my paper ``Families of regular matroids'' which is on the ArXiv.
Napomena: Zamišljeno je da oba predavanje budu preglednog karaktera, pristupačna i interesatna širem krugu slušalaca uključujući i mlade matematičare i studente.

Predavač: Rade Živaljević
Naziv predavanja: Matroidi, 15-minutni kurs za nespecijaliste.
U Beogradu će kao gost Matematičkog fakulteta i Matematičkog instituta od 13-16. jula boraviti poznati američki matematičar Kiyoshi Igusa (Brandeis University).
Profesor Igusa će održati predavanje 13. jula u redovnom terminu CGTA seminara, kao i predavanje na Odeljenju za matematiku MI SANU, u petak, 16.07.2010. 14 časova, sala 2 SANU pod naslovom THE CATEGORY OF REGULAR MATROIDS.
Naš plan je da na sastanku 6.07. napravimo pregled fascinantne (!) teorije matroida i pokušamo da objasnimo kako i zašto se krug zatvorio u algebarskoj topologiji. Začetnik teorije matroida je isti onaj Hassler Whitney koji je koautor Stiefel-Whitney-ovih karakterističnih kohomoloških klasa a profesor Igusa (http://people.brandeis.edu/~igusa/) je poznat po svojim velikim doprinosima topologiji i geometriji (higher torsion invariants of smooth bundles itd.)

Napomena (R.Živaljević, CGTA-seminar): Profesor Igusa je vrlo poznati specijalista za algebrasku topologiju ali i mnoge druge oblasti matematike. U podnaslovu rada ''Families of regular matroids'', arXiv:0911.2014v2 [math.CO], na kome je bazirano ovo multidisciplinarno predavanje, stoji:
"This paper is dedicated to my late friend, relative and fellow Mathematician Dragan Acketa who loved matroids".
