    At Classroom 17

    Abstract:  A group is a set of elements together with a binary operation and four defined properties: closure, associativity, existence of the unit element and existence of the inverse of each element. At the most basic level, group theory systematizes the notion of symmetry, that can be applicable whether of geometric objects, crystals, roots of...

    At Classroom 17

    Abstract: The ongoing transformation of biology to a quantitative discipline has drastically increased our opportunities to unravel the mechanisms that relate the dynamics of biological systems to their functions as it allows for the investigation of such systems at spatial and temporal scales never observed before. The biggest challenge today is to assimilate the wealth of informatio...

  • MCS Seminar: Tan Ser Peow. Hyperbolic jigsaws and families of pseudomodular surfaces

    6 September 2017 (Wed) , 14:30-15:20
    At Classroom 17

    Abstract: A pseudomodular group is a Fuchsian group which is not commensurable with the modular group PSL(2,Z) but which has cusp set all of the rationals, the corresponding surface is called a pseudomodular surface. We show that there are infinitely many commensurability classes of pseudomodular groups/surfaces, thus answering a question raised by Long and Reid. We...

  • MCS Seminar: Olivier Danvy. An axiomatic approach to scoring functions

    30 August 2017 (Wed) , 14:30-15:20
    At Classroom 17

    Abstract: We present an axiomatic scoring strategy for multiple-choice exams that credits partial knowledge and levels out guessing.  The scoring strategy equalizes the implicit weight of each question by default and makes this weight an optional parameter for each question.  Partial credit can also be modulated, which provides a measure of the spread of knowledge of the examinee.  Th...

  • MCS Seminar: Roozbeh Hazrat. Levitt path algebras

    13 March 2017 (Mon) , 13:15-14:15
    At K Chanrai (RC2-01-02)

    Abstract: From a directed graph one can generate an algebra which captures the movements along the graph. One such algebras are Leavitt path algebras. Despite being introduced only 10 years ago, Leavitt path algebras have arisen in a variety of different contexts as diverse as analysis, symbolic dynamics, noncommutative geometry and representation theory. In fact, Leavitt...

    15 March 2017 (Wed) , 14:30-16:00
    At Classroom 15, East Core

    Abstract: How can we use data and technology to solve hard problems and change the world for the better? Palantir builds sophisticated data integration and analysis software, and partners with government agencies, commercial institutions, and non-profit organizations to transform how they use data and technology. With Palantir technologies, inve...

  • MCS Seminar: Robby Tan. Computer Vision, Deep Learning and Bad Weather

    8 March 2017 (Wed) , 14:30-15:30
    At Classroom 16, East Core

    Abstract: Computer vision is part of artificial intelligence (AI) that focuses on images or video. Its goal to make computers “see” the world, like our eyes or beyond. It is useful for many applications, and recently is used a lot in self-driving cars, surveillance, mobile phones, and industry (such as Amazon Go, Google Image, Facebook Vision...

  • MCS Seminar: Mohamed Omar. Peak Polynomials

    10 March 2017 (Fri) , 18:00-19:00
    At Lecture Theatre 1, Saga

    Abstract: A permutation of the set {1, 2, …, n} is a rearrangement of it. In a given permutation, an element is a peak if it is larger than the numbers next to it. For instance, the permutation 1432 has a peak (only) in the second position. This talk investigates the question: How many permutations...
