    In many fields of science, researchers are keen to learn causal connections among quantities of interest. For instance, in medical studies doctors want to infer the effect of a new drug on the recovery from a particular disease, or economists may be interested in the effect of education on income.

    The preferred approach to causal inference is to carry...

  • Human and robot binaural sound source localization

    Karim Youssef

    Abstract:

    Abstract: With the growth of sound processing and intelligent systems technologies, it has become possible to endow robots and machines with human-like auditive capabilities. In this context, binaural audition emerges as a biologically-inspired and low-complexity sound processing domain, relying on signals captured by microphones emulating two ears. In this seminar, the focus will be on sound source...

    Title: 
    Causal discovery with functional causal models: Different types of "independence"
     
    Abstract: 
    Recently a class of causal discovery methods based on functional causal models has been proposed, which, under certain conditions, is able to fully identify the causal structure. Generally speaking, those methods make use of additional...

    Title
    Learning Chordal Markov Networks by Constraint Satisfaction
     
    Abstract
    We have investigated reducing the structure learning problem for Markov networks to various constraint satisfaction problems, and shown the resulting method to be competitive with an earlier stochastic local search method in finding good networks and also being capable of showing the...

    Title
    Knowledge Discovery in High Dimensional Data
     
    Abstract
    While data clustering has a long history and a large amount of research has been devoted to the development of numerous clustering techniques, significant challenges still remain. One of the most important of them is associated with high data dimensionality. A particular class of clustering algorithms...
  • Big data analytics for economic development

    Sunandan Chakraborty, New York University, US

    Abstract:

    The Web is a collection of vast and diverse datasets, like news articles, user posted articles, (e.g. blogs), social media (e.g. twitter), images, in addition to different governmental and non-governmental organization post structured data on their websites. My research is focused on building a generic big data analytics engine that can analyze parallel streams of diverse and noisy...

    Title
    Linear forms over semirings: algorithmic applications and complexity results
     
    Abstract
    Based on work included in my upcoming PhD thesis, I will discuss various topics related to the evaluation of linear transformations (or equivalently, matrix-vector multiplications) over different types of rings and semirings. The work is motivated by applications in...
  • 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...
