Guest lecture
R030/T6, Computer Science Building, Konemiehentie 2, 02150, Espoo, FIAbstract:
The most general data format in real world is a table or matrix, where columns are instance and rows are their features, and vice versa. Matrix factorization is useful to extract essential low-rank structures from a given matrix and has been increasing interest in data mining and machine learning. A typical example of matrix factorization is non-...

Exploring the diversity and quality in cluster ensemble and cluster ensemble selection (HIIT Events)23.02.2015 13:15–14:00
HIIT seminar
Lecture hall T2,Computer Science building, Konemiehentie 2, 02150, EspooAbstract:
Cluster ensemble first generates a large library of different clustering solutions and then combines them into a more accurate consensus clustering. It is commonly accepted that for cluster ensemble to work well the member partitions should be different from each other, and meanwhile the quality of each partition should remain at an acceptable level. Many...

Sequential Monte Carlo methods for Graphical Models
Prof. Thomas Schön, Uppsala University, Sweden
Abstract:In this talk I will introduce our new methods for inference in general probabilistic graphical models (PGMs). The key is a sequential decomposition of the PGM which provides a sequence of auxiliary distributions defined on a monotonically increasing sequence of probability spaces. By targeting these auxiliary distributions using Sequential Monte Carlo (SMC) methods we are able...

Cooperative Navigation for Robot Swarms
Prof. Sándor P. Fekete, TU Braunschweig, Germany
Abstract:In recent years, the field of robotics has achieved progress by increasing the capabilities of individual robots. This has produced good results, but keeps the cost of state-of-art machines relatively high. An alternative approach is to develop simpler, cheaper (and, with additional challenges and possibilities: smaller) platforms in large numbers, at the expense of reducing the...
