  • Advances in Multi-label Classification

    Dr. Jesse Read, University Carlos III of Madrid, Spain

    Abstract:

    Multi-label classification has attracted much attention over the last few years, and its mention in the literature had expanded prolifically. In multi-label classification, each data instance may be associated with multiple classes, as opposed to a single class label (as in the traditional classification task). This context arises naturally in a wide variety of domains (text...

    Guest lecture
    OIH, Otaniementie 19, Espoo

    Abstract: Modern Web, which is frequently called Social Web or Web 2.0,
    celebrates the power of the user community. Most frequently it is
    associated with the power of users as contributors or various kinds of
    contents through Wikis, blogs, and resource sharing sites. However, the
    power of the user community impacts not only the production of Web content,
    but also access to...

    Title
    Exploration and retrieval of whole-metagenome sequencing samples
     
    Abstract
    Over the recent years, the field of whole metagenome shotgun sequencing has witnessed significant growth due to the next generation sequencing technologies that allow sequencing genomic samples cheaper, faster, and with better coverage than before. This technical advancement has...
  • Chaos and Control

    Prof. Elizabeth Bradley, University of Colorado, US

    Abstract:

    Understanding and exploiting the special properties of chaos can lead to designs that vastly improve the performance of many practical and useful systems --- spacecraft trajectories that require less fuel, for example, or tracking circuitry with broader capture ranges and fuel injectors that mix gasoline and air more effectively. Control strategies that leverage chaos's characteristic geometry, ergodicity...

  • Modeling human hand functions in mobile input for interface design and evaluation

    MSc. Joanna Bergström-Lehtovirta, HIIT

    Abstract:

    The hands are our primary means to manipulate the environment. Due to the large number of degrees of freedom and tremendous connection to neural system, hands can perform skilled movements and are a common input channel in human-computer interfaces. Mobile contexts, however, introduce immense number of physiological and cognitive tasks that affect manual...

    Title: Fast sequence segmentation using log-linear models

    Abstract:
    Sequence segmentation is a well-studied classic problem, where given a sequence of
    elements, an integer K, and some measure of homogeneity, the task is to split
    the sequence into K contiguous segments that are maximally homogenous.  A
    classic approach to find the...

  • Nyquist barrier - not for all!

    Dr. Jaan Pelt, Tartu Observatory, Estonia

    Abstract:

    Nyquist-Shannon-Kotelnikov-Whittaker theorem states that if a function does not contain frequencies higher than B Hz then it is completely determined by giving its ordinates at a series of points spaced 1/(2B) seconds apart. It is this barrier frequency B that is the topic of this talk. I will approach the barrier from both sides. First I will talk about randomly spaced measurement series. This is the...

    Title
    Towards understanding of the three-dimensional chromosomal organization. A Bayesian model-based approach to analyze Hi-C data
     
    Abstract
    Understanding how chromosomes fold provides insights into transcription regulation and hence functional state of the cell. Recently, chromosomal...
