Abstract: With the growth of sound processing and intelligent systems technologies, it has become possible to endow robots and machines with human-like auditive capabilities. In this context, binaural audition emerges as a biologically-inspired and low-complexity sound processing domain, relying on signals captured by microphones emulating two ears. In this seminar, the focus will be on sound source...

Title: 
Causal discovery with functional causal models: Different types of "independence"

Abstract: 
Recently a class of causal discovery methods based on functional causal models has been proposed, which, under certain conditions, is able to fully identify the causal structure. Generally speaking, those methods make use of additional properties of a causal system other than conditional...

Title: Human and robot binaural sound source localization

Abstract:
With the growth of sound processing and intelligent systems technologies, it has become possible to endow robots and machines with human-like auditive capabilities. In this context, binaural audition emerges as a biologically-inspired and low-complexity sound processing domain, relying on signals...

Abstract

The talk deals with the computation of repetitions occurring in a string. It first shows an optimal O(n log n)-time solution for computing factors having an exponent at least 2 in a string on an infinite alphabet.

Then it shows how to design an algorithm to compute the maximal exponent of factors of an overlap-free string. The algorithm runs in linear-time on a fixed-size alphabet, while a naive...

The University of Helsinki and the PROSECCO Network for Promoting the Scientific Exploration of Computational Creativity will organize an international autumn school on computational creativity. We cordially invite PhD and MSc students and interested researchers to participate in the school.

Abstract
Understanding complex phenomena and solving difficult problems often requires knowledge from different domains to be combined and cross-domain associations to be taken into account. These kinds of context-crossing associations are called bisociations (Koestler, 1964) and are often needed for creative, innovative discoveries. The ability of text mining...

Mobile ad hoc networks (MANET) are useful tools for many purposes, e.g. for pervasive social networking. They may be used to complement social media tools available over the Internet. In addition to more traditional security threats, issues with privacy and trust constitute a major challenge in this kind...
