HIIT seminar
Exactum, B119TitleKnowledge Discovery in High Dimensional DataAbstractWhile 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...

HIIT seminar
Exactum, B119TitleLinear forms over semirings: algorithmic applications and complexity resultsAbstractBased 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...

Guest lecture
OIH, Otaniementie 19, EspooAbstract: 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... -

Exactum, B119TitleExploration and retrieval of whole-metagenome sequencing samplesAbstractOver 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...
