STATISTICAL MACHINE LEARNING AND BIOINFORMATICS
The research group is based in Helsinki University of Technology
(Laboratory of Computer and
Information Science), and partly in
University of Helsinki (Department
of Computer Science). We are members of AIRC
(Adaptive Informatics Research
Centre, national CoE), HIIT (Helsinki
Institute for Information Technology), and PASCAL
(Pattern Analysis,
Statistical Modelling and Computational Learning, EU FP6 NoE).
The group develops machine learning methods for statistical data
mining, information visualization, exploratory data analysis, and in
general for probabilistic modeling of data. By machine learning we
mean flexible statistical models usable in several applications.
The methods are being developed in bioinformatics and information
retrieval projects, where we collaborate with groups of the
application areas. The idea is to use the applications as testbenches
for the methods, and the methods for solving research problems
in the application area.
Our current methodological foci include discriminative generative
modeling, data fusion by modeling dependencies between data sets,
supervised unsupervised learning, and models for defining and
extracting "relevant" signals from data.
