New Approaches for Analyzing Multivariate and Infinite Dimensional Data
Pauliina Ilmonen, Assistant Professor, Statistics, Department of Mathematics and Systems Analysis, Aalto University
In modern data analysis, we often have to deal with very complicated observations. Dimensions can be very large and contain complicated dependency structures. Observation may be e.g. images, bits, colors, or functions. Classical statistical methods that rely on normality and i.i.d. observations can give faulty results or are at least inefficient for analyzing modern data. We approach this problem in three ways:
We develop new methods for modelling multivariate extreme values. We provide new estimators for multivariate tail indices and multivariate extreme quantiles.
We consider general location-scatter-models and invariant coordinate selection – methods that do not rely on normality assumptions and can be applied for analyzing multivariate and even tensor-valued observations.
We develop new nonparametric methods for analyzing infinite dimensional – functional – observations. We consider outlier detection and different types of classification and clustering problems.
Attentive Futures: Cognition under Control

It is estimated that most of the information ever produced by mankind is just a few years old. This change in the amount of available, and also potentially relevant information has been incredibly fast, while our brain and its very limited ability to handle new information has gradually developed during evolution under very different circumstances. The limitations in attention and executive skills are exacerbated in various clinical conditions (ADHD, autism, burn-out, depression, dementias) with rapidly increasing prevalence rates. Current health care relies on effortful, expensive, subjective, and inaccurate methods that cannot be provided for everybody in the need. I will introduce some new clinically and neuroscientifically motivated health tech solutions (online testing, mobile apps, VR games) that aim to advance the assessment and treatment of attention deficits in multiple ways. These systems provide massive amounts of reliable cognitive testing data, but unlike in other fields in computational psychiatry (symptoms data, digital phenotyping), neuroimaging or neurogenetics, there are only few researchers developing advanced computational methods for cognitive testing purposes. Cognitive testing data might be even particularly for data mining purposes because it is reliable and objectively measured (unlike symptoms data), and directly measures actual behavior (unlike neuroimaging and genetics data). Could we build together the road for individualized treatments supporting attentive futures?
NB! The talks begin at 9:30. Breakfast is served on a first-come-first-serve basis at 9:15. No need to pre-register. The event is free of charge
