Title: Geometric-topological tools for shape description

Lecturer: Barbara DI FABIO

Abstract: In shape comparison a widely used scheme is to measure the dissimilarity between signatures associated with each shape rather than matching shapes. In this context, computational topology plays an important role, offering a series of techniques and measures with an extremely high abstraction power. Persistent homology and Reeb graphs provide signatures able to describe shapes from topological and geometrical perspectives, being approaches grounding in the classical Morse Theory. The common idea underlying these methods, indeed, is to perform a topological exploration of the shape according to some quantitative geometric properties provided by a real-valued function defined on the shape and chosen to extract shape features. This seminar  provides an overview of these shape descriptors with related comparison methods, their main properties and drawbacks, some of the main theoretical and experimental results, recent developments, open issues and future perspectives.

Biography: Barbara DI FABIO is born in Lanciano (Italy) in 1977. In 2004, she graduated cum laude and, in 2009, received her Ph.D. degree in Mathematics at the University of Bologna with a work on the enhancement of geometrical tools for pattern recognition. Since then, she has been post-doctoral fellow at the excellence centre ARCES ”E. De Castro” (University of Bologna) and at the Department of Mathematics (Prof. Massimo FERRI, University of Bologna). Barbaras main research interests are focused on computational geometry and topology and include problems of shape analysis and understanding with related applications in computer vision, computer graphics and pattern recognition – highly relevant for machine learning and knowledge discovery. She attended several postgraduate schools and workshops, participated in and was author of several communications in national and international scientific conferences. She is author of 9 peer-reviewed papers, 5 proceedings and 1 preprint. She is a referee for several international journals. Since 2005 she has been teaching in undergraduate courses in Engineering and Economics, University of Bologna. At present, supported by an ESF exchange visit grant, she is working with Professor Neza Mramor Kosta at the Faculty of Computer and Information Science, University of Ljubljana.

*****************

Brain research is rapidly advancing with the application of big data technology to neuroscience as can be seen in major international initiatives in the US, Europe and Asia. BIH’15 reflects that brain informatics has emerged as a distinct field and crosses the disciplines of neuroscience, cognitive science, computer science, signal processing, and neuroimaging technologies as well as data science. Following the success of past conferences in this series, BIH’15 will take place at Imperial College London, in UK, gathers the researchers from major international brain research projects, and plans an industrial exhibition.

BIH’15 draws special attention to informatics for brain science, human behavior and brain health. BIH’15 will address big data approaches to both the brain and behaviour, with a strong emphasis on emerging trends of big data analysis and management technology for BI, active media technology in behavior learning, and real-world applications for brain and mental health.

BIH’15 welcomes paper submissions (full paper and abstract submissions). Both research and application papers are solicited. All submitted papers will be reviewed on the basis of technical quality, relevance, significance and clarity. Accepted full papers will be included in the proceedings by Springer LNCS/LNAI.

Banff Meeting approved

We just received the message from the Scientific Director of the BIRS – Banff International Research Station for Mathematical Discovery, that our 7th International Meeting of the expert group HCI-KDD “Advances in interactive Knowledge Discovery and Data Mining in complex and big data sets” (BIRS Approval Nr. 15w2181) has been approved by the scientific committee for the dates July 24 – July 26, 2015. So, the Holzinger Group has now the possibility of being at the holy grail of computational mathematics 🙂
http://www.birs.ca/

NB.: The area around Banff is the world’s most dense area of paleontological findings.
Banff is 78 miles west of Calgary at a hight of approx. 5000 ft. with subarctic climate,
temperatures during our meeting end of July are the highest of the year, in average 21 degrees Celsius.
Morning temperatures can go as low as 7 degrees Celsius – so pullovers are recommended 🙂
Those who are afraid of bears should not attend this meeting, as the Research Center is directly located within deep forest and in the morning Grizzly bears are usually foraging the trash bins.

The papers will be collected in a Springer Volume Lecture Notes in Artificial Intelligence (LNAI),
which is a more mathematical oriented topical subseries of the Lecture Notes in Computer Science (LNCS):

hci4all.at is now hci-kdd.org

Our website appears in a new light!

We welcome our visitors to our new hci-kdd.org website. In order to keep pace with time, our website is now responsive with a fresh design.

HCI4ALL is now HCI-KDD

Our digital world, full of mobile computing devices and ubiquitous sensor networks produce increasingly large, complex, high-dimensional and weakly structured data sets, and increasing volumes of unstructured information. These enormous amounts of data require novel, efficient and interactive solutions for knowledge discovery/data mining.  A synergistic combination of methodologies and approaches of two areas offer ideal conditions towards unraveling such problems: Human-Computer Interaction (HCI) and Knowledge Discovery/Data Mining (KDD), with the goal of supporting human intelligence with machine learning, putting the “human-in-the-loop “. Our goal is to interactively discover new, previously unknown insights into the data and we are passionate on extending advanced methods including time (e.g. information entropy) and space (e.g. computational topology), along with user-centered software engineering methods to create interactive software for mobile applications & content analytics techniques.

Science is to test crazy ideas – Engineering is to put these ideas into Business!
